There is no difference between something like "www" and "www2" other 
that they usually signify "www2" (using your example) is a different 
physical server than "www".  There are no "types" to choose from, as 
you could (or, rather, a network/server administrator could), in 
theory, use any combination of letters legal under the DNS.

The use of "www" was completely arbitrary to begin with, but is often 
useful to distinguish a network host running Web-server software at 
"ONE_COMPANY.COM"  from whatever server actually answers the door at 
ONE_COMPANY.COM.
