RFC 1035
The labels must follow the rules for ARPANET host names. They must
start with a letter, end with a letter or digit, and have as interior
characters only letters, digits, and hyphen. There are also some
restrictions on the length. Labels must be 63 characters or less.
//RFC 1035
I've also noticed 1and1.com doesn't fit this bill either. Most programs
should be able to handle labels starting with digits, however since it
is contrary to an active RFC which we as internet users are meant to be
using as a standard, it is obviously not best practice.
Just another example of the rules slipping so much that it's hard to
tell the good from the bad these days.
