| Ref: IETF RFC2182 (Abstract)
| The Domain Name System requires that multiple servers exist for every
| delegated domain (zone). This document discusses the selection of
| secondary servers for DNS zones. Both the physical and topological
| location of each server are material considerations when selecting
| secondary servers. The number of servers appropriate for a zone is also
| discussed, and some general secondary server maintenance issues
| considered.

f> Server doesn't listen/answer on port 53 for TCP protocol
| Ref: IETF RFC1035 (p.32 4.2. Transport)
| The DNS assumes that messages will be transmitted as datagrams or in
| a byte stream carried by a virtual circuit. While virtual circuits can
| be used for any DNS activity, datagrams are preferred for queries due
| to their lower overhead and better performance.
