If you searched for “opendns servers ip”, you probably want two things at once: the correct public resolver addresses and a fix for a connection problem on your own network. This troubleshooting guide covers both, with a clear focus on solving common OpenDNS problems rather than repeating a basic setup walkthrough. The public OpenDNS resolver addresses are 208.67.222.222 and 208.67.220.220, and those are the only resolver addresses you need for the checks in this guide. Everything here applies to your own home or small-office network, your own router, and your own devices. You should never change DNS settings on a network you do not own or manage, and you should never copy settings from someone else’s network. Work through the steps in order, test after each change, and keep a note of what you changed so you can undo it. That is the practical meaning of a search for opendns servers ip: not just the numbers, but a working fix for opendns servers ip problems on your own equipment.
Before you change anything, it helps to understand what the phrase “opendns servers ip” actually points to. In everyday language, people use it to mean the IP addresses of the OpenDNS public resolvers, the servers that turn domain names such as website names into IP addresses your devices can connect to. When those resolvers are working, browsing feels normal. When they are not reachable, or when a device is pointed at the wrong address, you can see errors such as pages that never load, a browser message saying the DNS address could not be found, or some apps working while others fail. The troubleshooting angle matters here because most OpenDNS problems are not caused by the public resolvers being down. They are usually caused by a typo in an address, a setting applied in two places that conflict, a cached old result, or a router that overrides what you set on a single device.
What “opendns servers ip” Means for Your Network
When people search for “opendns servers ip”, they are usually asking for the numeric addresses to enter in a router or device. The two well-known public OpenDNS resolver addresses are 208.67.222.222 and 208.67.220.220. Use the first as the primary address and the second as the secondary address. If you enter only one, your devices have no fallback when the first is briefly unreachable. If you enter a wrong digit, for example by swapping two numbers, your device will send queries to an address that is not a resolver, and lookups will fail even though your internet connection itself is fine. That distinction is important: a DNS failure can look exactly like having no internet at all, even when the line, the Wi-Fi signal, and the router are all working. Many readers who search for opendns servers ip are in exactly this confusing position, and checking opendns servers ip settings first saves a long detour into router replacement.
Another common source of confusion is the difference between a resolver address and your own network address. The “opendns servers ip” values above are public addresses owned by the resolver service. They are not your router address, not your computer address, and not a private address on your home network. Your router usually has a private address for local administration, and your devices receive private addresses from the router. Those local addresses and the public resolver addresses play different roles, and mixing them up is a frequent cause of trouble. Keep the public resolver addresses in the DNS fields only, and leave the local network addresses where your router manages them automatically unless you have a specific reason to change them. If you keep that separation clear, most opendns servers ip troubleshooting becomes a short checklist rather than a guessing game about opendns servers ip values.
First Checks When “opendns servers ip” Stops Working
Start with the simplest checks, because they solve a surprising number of problems. First, confirm whether the problem affects one device or every device on your network. If only one phone or laptop fails while others browse normally, the fault is almost certainly on that device, not on the resolver service. If every device fails at the same time, look at the router and the connection to your internet provider. Second, check whether some websites load and others do not. A single site failing usually points to that site or to a cached result, while every site failing points to DNS or to the connection itself. Third, restart the affected device and, if the problem is network-wide, restart the router as well, allowing it a full minute to come back up before testing again.
Next, verify the addresses you actually entered. Open the DNS settings on the device or router you changed, and read each number digit by digit against 208.67.222.222 and 208.67.220.220. Typing errors are easy to miss because the numbers look similar at a glance. Check that you have not accidentally entered the same address twice, left the secondary field blank on a device that needs both, or added extra spaces or dots. If you set DNS on both the router and a device, make sure they agree. A device setting usually overrides the router setting on that device, so a stale or mistyped device entry can keep failing even after you fix the router. For a clean test, set DNS in one place at a time and test before changing the other.
How to tell a DNS problem from a connection problem
A useful test is to compare a name-based connection with a number-based one, using only public and well-known test targets you already know. If a familiar website name fails but your router admin page still opens, the local network is working and name resolution is the likely fault. If nothing loads at all, including the router page, the problem is more likely local Wi-Fi, cabling, or the link to your provider. Also try a different browser or app on the same device. If one browser fails and another works, clear the failing browser cache or check its proxy settings, because the network itself may be fine. Record what each test shows, since that pattern is exactly what helps you narrow the fault instead of changing settings at random. A short written note of your opendns servers ip entries, before and after each change, is the single habit that prevents repeated opendns servers ip mistakes.
Common “opendns servers ip” Problems and Their Fixes
The most common problem is a mistyped resolver address. The fix is straightforward: re-enter 208.67.222.222 as primary and 208.67.220.220 as secondary, save, and then flush or refresh the DNS cache on the device so it stops using the old failed result. On many systems this happens automatically after a restart, which is why a restart sometimes appears to fix the problem on its own. If you changed the router, restart the devices as well, because devices can hold on to the old DNS information until their network lease renews. Do not change three settings at once. Change one, test, and only then move on, so you know which change actually fixed it. This one-change rule applies to every opendns servers ip fix, from a simple typo to a full opendns servers ip reconfiguration on the router.
The second common problem is a stale cache. Devices and browsers remember past lookups to save time, but a remembered failure can linger after the underlying problem is fixed. If a site worked yesterday and fails today after a settings change, clearing the browser cache and restarting the device is a sensible next step. The third common problem is a conflict between settings: DNS set on the router, different DNS set on the device, and a VPN or security app adding its own DNS on top. If you use a VPN, test with it disconnected, because many VPN tools route DNS through their own resolvers while connected, which can override your OpenDNS settings entirely. That is not a fault, but it does mean your OpenDNS test results will not be meaningful until the VPN is off.
The fourth common problem is filtering or parental controls that block more than expected. Some OpenDNS-based setups use filtering profiles that block categories of sites. If ordinary, safe sites fail while a search engine loads, check whether a filtering profile is active on your account or router and whether the device is assigned to a filtered profile. Test from a device that should be unfiltered, if your own setup has one, and review the blocked categories. The fifth common problem is an internet provider or local firewall that intercepts DNS traffic. In that case, changing the resolver address alone may not help, because queries are redirected before they leave the network. If you suspect this, check your router firewall settings and any security software on the device, and test on a different network you own, such as a phone hotspot you control, to see whether the same settings work there. That comparison test is the fastest way to tell whether an opendns servers ip fault lives in your router or in the wider opendns servers ip path to the resolver.
| Symptom on your network | Likely cause | First fix to try |
|---|---|---|
| Every site fails on every device | Wrong resolver address on the router, or provider outage | Re-enter 208.67.222.222 and 208.67.220.220, restart router and devices |
| One device fails, others work | Mistyped or stale DNS on that device | Correct the device DNS, restart the device |
| One site fails, others load | Stale cached result or site-side issue | Clear browser cache, restart device, retry later |
| Sites fail only with VPN on | VPN DNS overriding your settings | Disconnect VPN and retest before changing DNS |
| Safe sites blocked unexpectedly | Filtering profile active | Review the filtering profile assigned to that device |
| Settings look right but nothing resolves | Firewall or provider DNS interception | Check firewall rules, test on another network you own |
Router and Device Checklist for “opendns servers ip”
Work through this checklist slowly, and tick off each item before moving to the next. First, confirm the router is connected to your provider and that its status lights show a normal connection. Second, confirm the DNS fields on the router contain 208.67.222.222 and 208.67.220.220 with no typos, and that you saved the change. Some routers need a restart or a reconnection before new DNS settings take effect. Third, check one device at a time: confirm it is connected to your own network, confirm its DNS setting matches the router or is set to obtain DNS automatically from the router, and restart it. Fourth, test with a plain browser visit to a well-known site. If it loads, the core problem is solved, even if one app still needs its own cache cleared.
If the router settings are correct but a single device still fails, inspect that device more closely. Check for a manually set DNS entry left over from an earlier setup, a proxy setting that is still enabled, or security software with its own DNS protection feature. Mobile devices can also hold separate DNS settings for Wi-Fi and for mobile data, so test on Wi-Fi with mobile data off to isolate the Wi-Fi path. On a laptop, check whether the problem follows the device to another network you own. If it works elsewhere, the fault is in your home router configuration. If it fails everywhere, the fault is on the device itself, and a network settings reset on that device is a reasonable next step, noting that it will forget saved Wi-Fi networks and you will need to reconnect.
For more background on local network terms, see our guide to another name for a network, and if you work on Linux systems, our guide to the command to know the IP address in Linux can help you check what address a machine is actually using. A further useful reference is our walkthrough for a Debian static IP address setup, which explains how manual address settings interact with DNS. These internal references are useful because DNS problems often turn out to be address problems in disguise: a device with the wrong local address, an expired lease, or a manual setting that conflicts with the router will fail in ways that look like resolver trouble.
When to Revert Your “opendns servers ip” Settings
Not every problem should be solved by pushing forward. If you have checked the addresses, restarted the router and devices, ruled out VPN and filtering issues, and name resolution still fails on your network while it works on another network you own, reverting to automatic DNS from your provider is a sensible diagnostic step. Set the router and device DNS back to automatic, restart, and test. If browsing returns to normal, the fault lies in how the custom resolver settings interact with your provider or router, and you can reapply the OpenDNS addresses one device at a time to find where the conflict appears. If browsing still fails on automatic DNS, the fault is not the resolver choice at all, and you should focus on the connection, cabling, Wi-Fi, and provider status instead.
Keep a simple log as you go: what you changed, the old value, the new value, and the test result. This habit saves a great deal of time, especially when a problem returns weeks later or when someone else in the household changes a setting. It also prevents the classic troubleshooting trap of changing the same setting twice in opposite directions without realising it. Once the network is stable, leave the settings alone. Repeatedly switching resolvers in search of a speed gain rarely produces a noticeable difference for everyday browsing, and each switch introduces a new chance for a typo or a stale cache. Stability, correct addresses, and a clean test after each change are worth more than constant tweaking.
Frequently Asked Questions About “opendns servers ip”
What are the public OpenDNS resolver addresses?
The public OpenDNS resolver addresses are 208.67.222.222 as the primary address and 208.67.220.220 as the secondary address. Enter them exactly, with no extra digits, spaces, or dots, in the DNS fields of your router or device.
Why does one device fail while others work?
That pattern usually means the failing device has its own mistyped, stale, or overridden DNS setting. Check that device individually, correct its DNS entries, clear its browser cache if needed, and restart it before changing anything on the router.
Does restarting the router really help?
Yes, often. A restart forces devices to renew their network information and drop stale cached results. Allow the router a full minute to come back up, then restart the test device as well, so both ends are using the new settings.
Can a VPN break OpenDNS settings?
A VPN can override DNS while it is connected, routing lookups through its own resolvers instead. Disconnect the VPN and retest before concluding that your OpenDNS settings are at fault.
Should I set DNS on the router, the device, or both?
Setting it on the router covers every device at once and is usually the cleanest choice. Setting it on one device is useful for testing. Avoid setting different values in both places, because the device value will override the router value on that device and can hide a router-side fix.
Conclusion
Most problems behind a search for “opendns servers ip” come down to a small set of causes: a mistyped address, a stale cache, a conflict between router and device settings, a VPN override, or a filtering profile doing more than expected. By confirming the correct public addresses, 208.67.222.222 and 208.67.220.220, testing one device and one change at a time, and reverting to automatic DNS as a diagnostic step when needed, you can isolate the fault on your own network without guessing. Keep a note of every change, test after each step, and leave the settings stable once browsing is working again. If the fault persists on automatic DNS and on other networks you own, the next step is to check the connection itself and your provider status rather than continuing to adjust resolver settings.
