Italc connection via hostname

Has anyone gotten iTalc to connect using hostnames under Linux? I can connect with mu opensuse master machine using IPs, which necessitates static IPs. I’d like to be able to use hostnames allowing me to go back to using dynamic IPs.

I have a mixture of XP, 2k and various Linux based workstations. The Windows machines authenticate via Active Directory logons.

Any and all help appreciated.
