IPv6 addresses of the CUDN central nameservers

2011-08-23 - News - Chris Thompson

The IPv6 routing prefixes for the vlans on which the CUDN central nameservers are located are being altered. As a result, their IPv6 addresses are changing as follows:

               Old IPv6 address          New IPv6 address
authdns0.csx   2001:630:200:8080::d:a0   2001:630:212:8::d:a0
authdns1.csx   2001:630:200:8120::d:a1   2001:630:212:12::d:a1
recdns0.csx    2001:630:200:8080::d:0    2001:630:212:8::d:0
recdns1.csx    2001:630:200:8120::d:1    2001:630:212:12::d:1

The new addresses are working now, and the old addresses will continue to work as well until Monday 5 September, when they will be removed. If you are using them (e.g. in nameserver or stub resolver configuration files) you should switch to the new addresses (or the IPv4 ones) before then.

The comments in the sample configuration file


about using IPv6 addresses to address the nameservers have been modified appropriately.
