Which IPs retrieve slave zones by AXFR?
In general, our DNS servers ns1 and ns3 retrieve slave-type zones by AXFR. For this, the following IPs are used:
- 134.0.30.178
- 194.126.196.2
- 2a03:2900:3:1::2
- 2a03:2902:3:1::2
ns2 does not retrieve the zones itself. Ns2 is our free Anycast DNS. Ns2 automatically synchronizes with one of the other two DNS servers as soon as they have updated the corresponding zone. Therefore, it is not necessary to send notifications to ns2. Notifications are rejected by ns2.
