A name server's name has no IPv4 or IPv6 address.

NS_UNRESOLVABLE · Severity: Warning

• WarningNS_UNRESOLVABLE

  A name server's name has no IPv4 or IPv6 address.

  Resolvers cannot reach a name server whose name does not resolve, so every query sent its way fails and has to be retried with another server. The evidence names the server; a typing error or an expired domain is the usual cause.

  Recommendation: Fix the name server's address records or remove it from the NS set.
