message:
  Use IPv6 localhost nameserver on DNS configuration errors
  
  When DNS configuration fails to locate a set of nameservers "localhost"
  is used as the default but has previously only been setting 127.0.0.1
  IPv4 address for localhost. This enables the failover to work as 
  designed on IPv6-only networks.
