    NS sets differ
    The nameservers at the parent and in the zone should be the same. Only at the parent: a.zeit-world.co.uk, b.zeit-world.org, c.zeit-world.com, f.zeit-world.net; only in the zone: ns1.vercel-dns.com, ns2.vercel-dns.com. a.zeit-world.co.uk, b.zeit-world.org, c.zeit-world.com, f.zeit-world.net, ns1.vercel-dns.com, ns2.vercel-dns.com report NS ns1.vercel-dns.com ns2.vercel-dns.com.
    #7
  • ✓ No glue needed #8
    All nameservers are outside the zone, so no glue records are needed.
  • ✓ 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 2 IPv4 /24s and 2 IPv6 /48s.
  • i
    All nameservers in one AS
    All nameserver addresses are announced by one network operator (AS62597 (NSONE - NSONE Inc, US): 11 addresses). An outage or attack on that network affects all nameservers; large anycast providers mitigate this, but a secondary DNS provider adds independence.
    #11
  • ✓ Nameserver names under 4 TLDs #12
    Nameserver names use the TLDs .com, .net, .org, .uk.
  • i
    Partly IPv6
    These nameservers have no IPv6 address: f.zeit-world.net.

    Very low TTLs
    These records have a TTL below 5m, causing extra queries and slower lookups: MX (1m). Low TTLs are useful just before a planned change. The NS TTL at the parent is 1h and in the zone 1d; resolvers may use either.
    #32
  • ✓ No CNAME at the apex #33
    The zone apex has no CNAME record.
  • i
    Wildcard record
    A random name under the zone resolves, so there is a wildcard (*) record. Typos and non-existent hosts resolve too, which can confuse mail and certificate checks.

  • ✓ CAA restricts issuance #35
