Can a computer have multiple domain names?

3.5. Can a computer have multiple domain names?

Yes. It is common for a site to have multiple names that are assigned to the same IP address. For instance, the following names

beetle.big-bug.com
ftp.big-bug.com
big.bug.com
stink.bug.com
volkswagen.bug-lovers-association.org could all point to a single computer with one IP address.
It would be very unusual for different top level domains to point to a single host, however. I think it more likely that big-bug.com_ could point to the same address as ftp.big-bug.com, stink.big-bug.com,_ and such. It's incredibly unlikely that a host would show up in both .com and .org, that's for sure! --DT
