If you searched for “opendns servers ip“, you may have found a pair of numbers and wondered what they actually are, why there are two of them, and whether they are safe to use. This guide answers those questions from the behind-the-scenes side: what OpenDNS resolver addresses mean, how they fit into the way the internet works, and which public addresses exist. The public OpenDNS resolver addresses are 208.67.222.222 and 208.67.220.220, and the rest of this article explains what those numbers do and why they matter.
OpenDNS is a public Domain Name System resolver service, now part of Cisco. Its job is to answer one question, billions of times a day: when a device asks for a website by name, what numeric address should it connect to? Every device on the internet has a numeric address, but humans remember names, so a translator is needed between the two. That translator is the DNS resolver, and OpenDNS offers its resolvers for anyone to use on their own devices.
What “Opendns Servers Ip” Means
The phrase “opendns servers ip” breaks down into three parts. “OpenDNS” is the name of the service. “Servers” refers to the computers that answer DNS questions. “IP” stands for Internet Protocol, the system of numeric addresses that identifies every device on the internet. Put together, the phrase asks for the IP addresses of the OpenDNS servers that answer DNS questions.
Those addresses are 208.67.222.222 and 208.67.220.220. They are written in the familiar dotted format used by IPv4, the older and still most widely used version of the internet addressing system. Each number between the dots ranges from zero to 255, and the four groups together identify one specific server or, in the case of a large service like OpenDNS, a global network of servers that all answer at the same address.
That last point surprises many people. When you send a question to 208.67.222.222, you are not necessarily reaching one single computer in one building. Large DNS providers use a technique called anycast, in which the same address is announced from many locations around the world, and your question is routed to the nearest one. The result is a faster answer and a service that keeps working even if one location has a problem.
How DNS Resolution Works Behind the Scenes
DNS resolution happens in milliseconds and usually without you noticing, which is why a search for opendns servers ip rarely explains what happens after you type the numbers in. When you type a website name, your device first checks its own memory, called a cache, to see if it already knows the answer from a recent visit. If not, it asks the resolver you have configured, which might be your internet provider’s server or a public resolver like OpenDNS.
The resolver then does the detective work. If it already knows the answer from its own cache, it replies immediately. If not, it asks a chain of authoritative servers, starting from the root of the naming system, then the servers responsible for the ending of the name, and finally the servers responsible for the specific domain. Each step narrows the search until the correct numeric address is found, and the answer is passed back to your device. Your browser then connects to that numeric address and loads the page.
This chain is why DNS matters for both speed and reliability, and why the opendns servers ip pair points at a global network rather than one machine. A slow or distant resolver adds a delay to every new website you visit, while a fast, well-distributed resolver answers quickly. It is also why a DNS outage feels like the whole internet is broken: your connection may be fine, but without the address book lookup, your browser does not know where to go.
Primary and Secondary: Why Two OpenDNS Addresses Exist
OpenDNS publishes two addresses because redundancy is a core principle of internet design, and anyone who looks up opendns servers ip will find the same matched pair. The primary address, 208.67.222.222, is the first server your device asks. The secondary address, 208.67.220.220, is the backup it asks if the primary does not answer promptly. Devices are designed to try the primary first and fall back to the secondary without you noticing, which keeps browsing working through brief server problems or network hiccups.
It is important to enter both addresses whenever a setup screen offers two fields, which is the practical lesson behind every opendns servers ip list. Entering only the primary leaves you with a single point of failure, while entering only the secondary works but ignores the intended order. The pair is designed to be used together, and every setup guide for OpenDNS, including a router setup, lists them as a matched set.
Some users ask whether the two addresses do different things. They do not. Both answer the same DNS questions from the same global network. The difference is only one of priority: primary first, secondary as backup. Think of them as two doors into the same building rather than two different buildings.
OpenDNS Addresses Compared With Your Provider’s DNS
By default, most home connections use the DNS servers provided by the internet service provider. A search for opendns servers ip is usually the first step away from that default. Those servers work perfectly well for most people, and there is nothing wrong with using them. Public resolvers like OpenDNS exist as an alternative, not a replacement that everyone must adopt. The reasons people switch are usually practical: a provider’s servers may be slow, unreliable, or difficult to reach from certain locations, while a global anycast resolver may answer faster.
OpenDNS also offers additional services built on top of its resolvers, including optional content filtering and security features that block known malicious domains. Those extras are separate from the basic opendns servers ip pair itself. Those features belong to separate OpenDNS products and accounts, and they are not switched on simply by typing in the public addresses. The public addresses on their own provide standard resolution, which is the baseline service most home users want when they look up opendns servers ip.
Choosing between your provider’s DNS and a public resolver is a matter of preference and testing. Some users measure a small speed improvement, others notice no difference, and a few prefer to stay with their provider for simplicity. Because the change is reversible, there is little risk in trying a public resolver on your own network and switching back if you see no benefit.
Public Addresses, Private Addresses, and What Not to Share
It is worth drawing a clear line between public resolver addresses and private network details, because an opendns servers ip list should never include your own household addresses. The OpenDNS addresses in this article are public by design: they are published by the service for anyone to use, and sharing them is harmless. Your own home network details are different. The addresses of your router’s admin page, your personal devices, and any custom server you run at home are private to your household and should not be published or shared with strangers.
The same principle applies in reverse. When you read a guide that lists DNS addresses, check that the addresses come from the provider’s own public documentation or a reputable source, and be wary of any opendns servers ip page that adds unexplained extra numbers., and be cautious of lists that mix public resolvers with addresses belonging to unknown third parties. A trustworthy public resolver list names the provider, gives a primary and a secondary address, and explains what the service does. The OpenDNS pair meets all three tests.
Opendns Servers Ip: The Public Resolver Address List
| Address | Role | Format | Use |
|---|---|---|---|
| 208.67.222.222 | Primary resolver | IPv4 | First DNS server field on your own router or device |
| 208.67.220.220 | Secondary resolver | IPv4 | Second DNS server field, as backup |
That short table is the complete public list most home users need, and it answers the opendns servers ip question without extra clutter. OpenDNS operates a much larger network behind those two addresses, with servers in many cities, but the anycast design means you never need to know the individual server locations. The two addresses are your doorway into the whole network, wherever you are.

Frequently Asked Questions About OpenDNS IP Addresses
What are the OpenDNS server IP addresses?
The public OpenDNS resolver addresses are 208.67.222.222 as the primary server and 208.67.220.220 as the secondary server. Both are IPv4 addresses operated as a global anycast network.
Why does OpenDNS have two IP addresses?
Redundancy. Your device asks the primary address first and falls back to the secondary if the primary does not answer. Using both avoids a single point of failure in the address lookup step.
Are OpenDNS IP addresses free to use?
Yes. The public resolver addresses are offered for anyone to configure on their own devices, which is the whole point of publishing an opendns servers ip pair. Separate OpenDNS products with filtering and business features may have their own accounts and terms, but the basic public resolvers are free to use.
Do OpenDNS addresses hide my browsing from my provider?
No. Changing DNS changes only which server translates names into addresses, so an opendns servers ip change alone does not make browsing private. It does not encrypt your traffic or hide your activity from your internet provider, and it is not a substitute for a VPN.
What happens if I enter the addresses in the wrong order?
Very little. Both addresses answer the same questions, so swapping them still works. The recommended order is 208.67.222.222 first and 208.67.220.220 second, matching the primary and secondary roles.
Conclusion
Behind the simple search phrase opendns servers ip sits a piece of internet infrastructure most people never see: a global network of resolvers that turns the names we remember into the numbers computers need. The public doorway into that network is just two addresses, 208.67.222.222 and 208.67.220.220, working as a primary and secondary pair so that a brief problem with one never stops your browsing. Whether you use them or stay with your provider’s servers, understanding what those numbers mean puts you in control of a small but fundamental part of how your own devices reach the internet.
