Jimmy, I'd like to point out that it is NOT possible to calculate the netmask. (at best you can calculate the network class). The problem is that you can't tell if there is some sub (or super) networking going on. so your only option is to *ask* the provider. (see ip-subnetworking howto)

Hi Daniel, I used a network calculator to get the following information. According to it you should use a netmask of 255.255.255.0.
