I'm curious - what's wrong with starting DNS A records off with numbers? dig +short 4test.shephard.org 4.2.2.2

  Illegal according to the RFC syntax for a DNS "label": http://tools.ietf.org/html/rfc1035#section-2.3.1 http://tools.ietf.org/html/rfc1035#section-2.3.1

    One aspect of host name syntax is hereby changed: the restriction on the first character is relaxed to allow either a letter or a digit. Host software MUST support this more liberal syntax. -- http://tools.ietf.org/html/rfc1123#section-2 http://tools.ietf.org/html/rfc1123#section-2
