Thanks. That will solve the purpose.

Right. I think I should have framed my question more appropriately. I
am developing a generic library (.dll) that has to do communication
between all the machines that run that library at various points of
time. At different times, different set of machines might be connected
and running the library.In that case, its not possible to know what
all ip addresses will be involved in the communication? So, its not
possible to specify the ip addresses in the .conf file. Is there any
way around that? How do I make sure that all the participating
machines at any point of time are part of the network?
