Re: Server naming conventions

a wise man long ago decided to decouple the server purpose from the server name.
physical servers get retasked confusing inventory and tracking and management.

physical servers use tree names...
  fig / elm / oak / catalpa / pine / cedar / ...
then DNS CNAMEs pointing the purpose to the host.
  smtps -=> catalpa

our sister group used to use rocks/mineral. oak is easier to spell than tsavorite. (:
other groups on campus use cartoon characters and movie characters.


today with virtual servers, virtual servers are named based on purpose.
... a VM wouldn't be retasked. you'd simply create a new VM.

distinct names makes things easier to remember:
  catalpa is part of smtps
as opposed to:
  srv## is part of smtps

can't remember what this server does?
we have a file on each server with it's purpose.
login and cat a file.

What kinds of naming conventions do everyone follow when building new

Currently, our Windows hosts are named following the pattern 'its-w2ks#'
or similar, where the # is the next in the sequence, and the names are
published in DNS. What are the potential drawbacks or using a scheme
like this? Do you think it is any better or worse from a security
perspective than using something like 'its-oracle-1' which has the
service right in the name? We're concerned about disclosing the purpose
of the machine via its name, and are trying to get an idea of what other
schools do for their machines. Thanks in advance.
