In the hosting world this is very common, how many of those plesk boxes
out there with A,www-A and mail-A/MX point to same IP, tens of thousands
yielding hundreds upon hundreds of thousands of domains I'd say :)
Of course ISP's and large ASP/OSP's using internal prorietory setups
with separate servers for WWW/MX, and most businesses above SOHO,
would of course use separate servers and IP's.
Many of us techie types use SOHO/NAT etc (because we appreciate the pure
waste of IPv4 space carried out by many others) and other private systems,
just like hobbyists.
