[users@httpd] What defines www2?
Perhaps a daft question, but I have Googled and not found an answer. Some
websites start with WWW(?), why is this and where can one instigate this
change and does Apache accept this FQDN as it would any other?

Oh I see. Mmmmmmmmmmm! That's interesting. I have got quite a few FQDN for
mail, ftp and other domains and sub-domains. I just didn't think that the
"www" bit was changeable.

Actually I thought you can't use underscores with DNS? Has to be
dashes, last time I checked (which was a while ago).
Anyways the question may be taken literally as WWW means World Wide Web,
that's why. Most of us know that and started thinking historically,
philosophically and whimsically. ;-)
As others pointed out, the sub-domain names were conventionally used on
a per-server basis. This was possibly more necessary in the past when
multiple servers (either daemon programs or virtual hosts) simply
wouldn't run on a single machine, probably way before the www, so each
was on it's own machine. It's a common convention for organizational
administration. It makes it easier to distinguish between services when
looking at log files. In the current time, a single domain on a single
server could easily be overloaded, so there's often a different daemon
(FTP, mail, www) on differnt boxes. Each box or just each virtual host
might have a different function, so different names are used.
Most of the time, www.domain.com is mapped to domain.com, so a person
can use either. When other services are offered to the internet (mail,
FTP, SSH, and so on) it just makes sense to separate the names, even if
it's on the same box. Maybe at some later time you want to move
services to separate boxes due to resource utilization. Now they MUST
have a separate name. So using sub-domains lends itself to scalability.
Also, it later became a convention to let client programs look at the
host name and take a guess at which port to contact. ftp.domain.com
would be 21, www.domain.com would be 80, and so on. Without those
subdomains, a client can either try nothing, try one thing, or try
multiple things in what amounts to a simple port scan, which is
extremely inefficient and often considered hostile. Most of the time
we're using web browsers, so they try port 80 only.

Server names are completely arbitrary. You can call your server www,
www2, waldo, or happy_fun_dragon. It's entirely up to you. The
convention of naming servers after the service that runs on them makes
sense, but is by no means required.

By and large, this is the naming convention that I was brought up with and
have utilized to this day. It would appear that events have made way for
change. Thanks for the clarification.

This is a good idea for the secure web side of my business.

Hiya
Normally www2 is used where there is more than one server involved with a
website. An example would be where one server is for normal access and
another machine on a different IP is used for secure access.
It doesn't signify anything in particular and is just another subdomain, but
another example is the way I use it - my www (www.zoeballz.tv) is a rented
server and is my "main" server. www2 is actually on a machine in my office
where I can directly edit a live webpage if necessary, or wish to give
someone a download without having to mess about uploading it (in other words
I can just copy file into web area by local net).
I hope this helps.

Back in the day (and still to a lesser extent today) you would name a
host based on by which protocol it would be accessible. So the gopher
host was gopher.example.com, the ftp host was ftp.example.com, the news
host was news.example.com, the smtp host was smtp.example.com, the web
host was www.example.com, etc. The convention is not necessary.
