To quote Marty on this:  "Snort will never do DNS resolution."

It really doesn't make sense to do it.  Extra CPU cycles, by doing the lookup
you might clue Mr. Hax0r that an IDS just saw him, denial of service, etc...

If you can't live without hostnames, then do some sort of post-processing.
Use a Perl script to parse the logs and convert into hostnames.  Snort-stat.pl
from the http://snort.sourcefire.com/ site will do this.
