Checks

  • ✓ 4 nameservers #6
    Delegated to nsa.scaleway.com, nsb.scaleway.com, nsc.scaleway.com, nsd.scaleway.com.
  • ✓ Parent and zone agree #7
    The parent delegation and the zone's NS records list the same nameservers.
  • ✓ Glue present and correct #8
    Glue is published for the nameservers inside the zone: nsa.scaleway.com, nsb.scaleway.com, nsc.scaleway.com, nsd.scaleway.com.
  • ✓ All names resolve #9
    Every nameserver name has an address and is not an alias.
  • ✓ Nameservers in different networks #10
    The nameservers are spread over 4 IPv4 /24s and 3 IPv6 /48s.
  • i
    All nameservers in one AS
    All nameserver addresses are announced by one network operator (AS12876 (AS12876 - Scaleway SAS, FR): 8 addresses). An outage or attack on that network affects all nameservers; large anycast providers mitigate this, but a secondary DNS provider adds independence.
    #11
  • 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.
    #12
  • ✓ All reachable over IPv6 #13
    Every nameserver has an IPv6 address.

    Very low TTLs
    These records have a TTL below 5m, causing extra queries and slower lookups: A (1m22s), AAAA (1m25s). Low TTLs are useful just before a planned change. The NS TTL at the parent is 2d and in the zone 4h; resolvers may use either.
