On Tue, 30 Jun 1998 13:22:34 +0200, you said:
RFC 1035, "DOMAIN NAMES - IMPLEMENTATION AND SPECIFICATION":

[...]
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.
                             ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

As amended by RFC1123, section 2.1:

      Host software MUST handle host names of up to 63 characters and
      SHOULD handle host names of up to 255 characters.

So if you're dicking with the code, make sure you get the limit *right*. ;)
