[TriLUG] resolving hostnames

If I have multiple IP addresses aliased to a single adapter (i.e. eth0:0
and eth0:1, etc) and have then assigned to the same hostname in /etc/hosts:
192.168.1.51 testhost
192.168.1.52 testhost
192.168.1.53 testhost
how can I verify that testhost is 'registered' to all those addresses
within the Linux networking config?
In more detail: There is a Java API to get the list of addresses that
are associated with a hostname. On our RH box, this correctly returns
a list of IP addresses...on another it does not (a customer's box, of
course). I'm trying to verify that the customer has properly configured
the addresses. Other than looking at /etc/hosts, is there a way to
get this information. For instance, IFCONFIG tells me exactly what
configuration the network service is using, rather than what's in the
config files.
I hope that made sense...
TIA,
Chris
