    2 nameservers
    Two nameservers meet the minimum; RFC 2182 recommends three or more for important zones: ns1.a20.com, ns2.a20.com.
    #6
  • !
    NS sets differ
    The nameservers at the parent and in the zone should be the same. Only at the parent: ns1.a20.com, ns2.a20.com; only in the zone: ns1.50-6-174-130.www.hostgator.com, ns2.50-6-174-130.www.hostgator.com. ns1.a20.com, ns2.a20.com report NS ns1.50-6-174-130.www.hostgator.com ns2.50-6-174-130.www.hostgator.com.
    #7
  • ✓ No glue needed #8
    All nameservers are outside the zone, so no glue records are needed.
  • ✗
    Nameserver names don't resolve
    These nameservers have no A or AAAA record, so they can't be reached (lame delegation): ns1.50-6-174-130.www.hostgator.com, ns2.50-6-174-130.www.hostgator.com.
    #9
  • !
    Nameservers in one network
    all IPv4 addresses are in 50.6.174.0/24. A single network failure takes all nameservers down; RFC 2182 recommends topologically separate networks (anycast setups are an exception).
    #10
  • i
    All nameservers in one AS
    All nameserver addresses are announced by one network operator (AS19871 (NETWORK-SOLUTIONS-HOSTING - Network Solutions, LLC, US): 2 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
  • i
    Partly IPv6
    These nameservers have no IPv6 address: ns1.a20.com, ns2.a20.com.

    Software version disclosed
    These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: ns1.a20.com: "PowerDNS Authoritative Server 5.1.4 (built Aug 10 2026 00:00:00 by root@bh-centos-9.dev.cpanel.net)"; ns2.a20.com: "PowerDNS Authoritative Server 5.1.4 (built Aug 10 2026 00:00:00 by root@bh-centos-9.dev.cpanel.net)". Hide or replace the version string.
    #17
  • ✓ Zone transfers refused #18
    No nameserver allows a zone transfer to the public.
  • ✓ TCP supported #19
    All nameservers answer over TCP.
  • ✓ EDNS supported #20
    All nameservers support EDNS(0).
  • ✓ Public addresses #21
    All nameserver addresses are publicly routable.
