Frequently asked questions

What are the CenturyLink DNS server addresses?

The IPv4 addresses are 205.171.3.65 and 205.171.2.65. No IPv6 addresses are listed for this service.

Do I need to be a CenturyLink customer to use them?

The live test on this page shows that they answer from outside the CenturyLink network. They are meant for subscribers, so they may be slower for others, and the provider can restrict them at any time.

Why is it slower from my location?

ISP resolvers sit near the ISP's own customers. From other regions the round trip is longer than for global resolvers such as Google or Cloudflare, which have servers in many countries.

Does CenturyLink DNS support encrypted DNS?

CenturyLink DNS does not document DNS over HTTPS or DNS over TLS support. Pick a provider that lists it if you want encrypted lookups.
