NS_SINGLE_TLD · Severity: Info

• InfoNS_SINGLE_TLD

  All name servers are under the same top-level domain.

  When every name server's name ends in the same top-level domain, a problem with that TLD's own name servers makes them all hard to resolve. Large providers spread their name servers over several TLDs for this reason.
