Greetings from sunny Melbourne Australia,

I want to get the subnet mask associated with the local PC's address.

I understand how to use hostname() and gethostbyname() to get a list of one or more addresses for this PC but I need to know whether this PC is on the same network as another address - hence my need for the subnet mask.

Can anybody help ?

Thanks in Advance
