One address family in one network

all IPv6 addresses are in 2001:638:d::/48, while the other address family is spread over several networks.

#10
✓ 2 autonomous systems #11

The nameservers are spread over: AS41289 (DWD-AS - Deutscher Wetterdienst, DE): 2 addresses; AS680 (DFN - Verein zur Foerderung eines Deutschen Forschungsnetzes e.V., DE): 6 addresses.
i

All nameserver names under .de

All nameserver names are under one TLD, so a problem with that TLD also makes the nameservers unreachable. Some operators use names under two TLDs for extra resilience.

Partly IPv6
