No, it shouldn't. There is some code in Mathematica that accesses the network for support of the license manager; it is possible that some of this code is being unnecessarily executed (most likely code which simply verifies the machine's IP address and/or hostname, or perhaps the code which initializes the Windows network libraries) and thus making spurious calls to the network. I don't know what the IP address is you've listed, but I wouldn't be surprised if it's your own machine, your gateway, or your DNS server. I'm curious whether you can simply suppress the communication via ZoneAlarm and still have Mathematica work. We'll add some tests to run a single-user license Mathematica with ZoneAlarm on its strictest settings for future versions of Mathematica, but I'm afraid there's not much that can be done for you right now.
