Recursive DNS servers

The struck-through names in the tables below are old names that are being deprecated as part of our renaming and renumbering project.

Default resolvers

These are the usual recommended DNS servers; for example, you will be using these servers if you connect to Wi-Fi / eduroam.

They implement DNS RPZ blocks and encrypted queries.

server names IPv4 IPv6 2001:630:212:8::d:0 2001:630:212:12::d:1

Pass-through resolvers

There are alternative DNS server addresses hosted on the same hardware as the default resolvers. These are available if you need un-blocked access to the DNS. They also provide encrypted queries.

If a legitimate site is blocked and this is causing problems for you, please report the error to CamCERT rather than switching to the pass-through resolvers.
