What Are OpenDNS DNS Server Addresses and Who Owns OpenDNS?

OpenDNS's public DNS server addresses are 208.67.222.222 and 208.67.220.220, and OpenDNS is now part of Cisco. You can use these two addresses to configure a device or router to route DNS queries through OpenDNS, and you can verify ownership and current product direction through the OpenDNS site's About, Support, and Dashboard links.

OpenDNS DNS server addresses

The OpenDNS site lists two public resolver addresses:

These are the addresses to enter when a device or router asks for primary and secondary DNS servers. The site presents them as the public-facing addresses for the service, not as a private or enterprise-only endpoint.

How to use them

1. Open the network or device settings where DNS servers are configured (router WAN/DHCP settings, or a computer's network adapter settings).
2. Enter 208.67.222.222 as the primary DNS server.
3. Enter 208.67.220.220 as the secondary DNS server.
4. Save the settings and reconnect the device or renew the DHCP lease so the new resolvers take effect.
5. Verify by checking the device's active DNS servers, or by visiting a DNS test page that reports which resolver answered the query.

Expected result: DNS lookups for devices on that network go through OpenDNS instead of the ISP's default resolvers. If the change does not appear to take effect, the common causes are a router that overrides manually set DNS, a device still holding an old DHCP lease, or a second network adapter with its own DNS settings.

Who owns OpenDNS

OpenDNS is now part of Cisco. The OpenDNS homepage states this directly and links to Cisco for more information. Practically, that means:

• The OpenDNS brand and consumer product suite continue to exist.
• Enterprise security capabilities are presented under Cisco Secure Access, which the site describes as providing protection against threats such as malware, phishing, and ransomware.
• The OpenDNS site still serves as an entry point for consumer products, support, and the dashboard.

What OpenDNS offers today

The site splits its offerings into two tracks:

Enterprise security

Cisco Secure Access is the enterprise-facing product, positioned as cloud-delivered protection against internet threats including malware, phishing, and ransomware. Organizations looking for the enterprise security capability should follow the Cisco Secure Access path rather than the consumer DNS addresses.

Consumer products

OpenDNS describes a suite of consumer products aimed at making internet faster, safer, and more reliable. The stated benefits are:

• Faster, more reliable home internet — the site attributes this to global data centers and peering partnerships that shorten routes between networks and OpenDNS data centers.
• Safer web browsing — filtering or pre-configured protection can block adult content and similar material, adding parental and content filtering controls to every device in the home.
• Easy setup — the site says setup is quick and does not require advanced technical knowledge, with guides and a knowledge base available.

Where to go for more information

The OpenDNS site provides several entry points:

• About Us — company and ownership information.
• Support — help guides and knowledge base.
• Dashboard — account and configuration management.
• Login — access to the dashboard for existing users.

If your goal is simply to point a home network at OpenDNS resolvers, the two addresses above are all you need. If your goal is enterprise threat protection, the relevant product is Cisco Secure Access, and the OpenDNS site is the starting point for reaching it.
