    all IPv6 addresses are in 2001:330:a::/48, while the other address family is spread over several networks.

    The nameservers are spread over: AS16509 (AMAZON-02 - Amazon.com, Inc., US): 1 address; AS6619 (SAMSUNGSDS-AS-KR-KR - SamsungSDS Inc., KR): 12 addresses.
  • i
    All nameserver names under .com
    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.
