Multiple Hosts using dyndns

[Daron]

Hi,
 
I trying to set up Tomcat 5.5 to respond to multiple host names that I have
configured using dyndns. I am not sure which facility I should be using.
Since my PC which is running tomcat only has one IP address I belive I need
to configure hosts, not virtual hosts. Am I correct? Also I am having
trouble finding information that seems completely related to what I am
trying to do. Can anyone recommend a site that addresses my issue?
 
Regards,
Daron Ryan.
