I guess we'll see what happens...
I do have a client who was told to do this, but was hosting their webserver on 2
different IP's and the 3rd party hosting company wants the domain A record to
point to them. I told my client, so how are people every supposed to connect to
your webserver without the www on the front now?
I just remember reading the RFC saying it's perfectly legit and workable...
In between the lines I read, "don't be surprised if strange things happen though".
Thanks for everyone comments. I realize this is a little OT for here.. but this
email list has some of the best admin-thinkers I'm on. So I appreciate the
thoughts. (and for Dave putting up with the post)
