Similarly, I did a presentation on this a while ago. This may be of some use. http://www.nanog.org/meetings/nanog31/abstracts.php?pt=NjExJm5hbm9nMzE=&nm=nanog31 (also: http://tinyurl.com/cuqv5e ) The details of the presentation are more geared to a multi-campus enterprise network (i.e. a university), but the two larger lessons that came out of moving the university over to a more standard naming scheme were: Derivability: Being able to synthesize the name with a few pieces of data makes naming and debugging easier. Longer is okay: Barring software limitations on name length, a longer name is not a problem if a person knows that they're going to get it right on the first try. We used CNAMEs if we wanted abbreviations. YMMV ....Matt
