IIRC, legal hostnames used to require a letter as their first character.
Not sure that's true any more, but the plugins are act as if it is.
Here's the comment in utils.c:
/* from 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. */
Now I'll have to go and find what RFC has superceded 1035, and read
that.
