Re: UDP packet/DNS server

  • From: Christopher Neill

Allowable characters in hostnames are:

a-zA-Z0-9

I think / is also allowable, and there is an RFC on this subject. Go to
ftp://nic.ddn.mil/pub/rfc to check.

On a side note, some DNS implementations do not adhere to this standard,
for instance Lose9[5|8] and other microsuck "products".

BIND 8 will not load a zone containing illegal characters. Jamie is absolutely
right (suprise!).

PS: jamie.. o-line baby..
