When sending request to the Men & Mice support team about DNS name resolution issues, please be aware that the Men & Mice team does not know your network internals.


DNS name resolution can be complicated, and the problem might be in a little detail. The Men & Mice support team needs to know which path a DNS query takes from a DNS client to the authoritative DNS Server that answers for this query.


Please provide as much information as possible in your request. Information on the topics listed below is helpful:

  • DNS Server products (unbound, BIND, MS DNS, PowerDNS ...) and versions being used
  • Operating systems used
  • configuration of the local "stub" resolver in the client operating system (TCP/IP Settings on Windows, /etc/resolv.conf on Unix)
  • authoritative zones configured on the DNS Servers
  • sub-zones configured on the DNS Servers (please provide information on the stub zones content)
  • forward-zones configured on the DNS Servers (aka "conditional forwarding" on Windows DNS)
  • global forwarding configured, including the level of forwarding ("forward-first", "forward-only", ...)
  • ROOT-Hint configured
  • Information on IPv6 and IPv4 connectivity
  • any DNS rewriting systems (like DNS64)
  • Information on DNSSEC validation and DNSSEC signed zones
  • a DNS name resolution diagram like the one below is always helpful and should exist for every DNS system
