tracert vs. getHostName

I have written a Java program that retrieves the host name of
a computer when I pass it an IP address. I am using a call
to getHostName() to do the translation. But, the host
name is not always returned. Sometimes I just receive the
same IP address back that I passed in. I would be content
with the fact that all translations are not going to give me an
answer, however, when I do a tracert, I DO get the name of
the computer. Hmmm. Can someone answer the following
two questions:
1) How is tracert getting the information and getHostName
is not.
2) Is there a way that I CAN programmatically get the translation
of the name?
I am running under Windows NT.
Thanks,
Bob Byron
