I did a Lookup on the IP address, and it's my ISP's (attbi.com -- now merged with Comcast). Mathematica still seems to work normally even if I just deny the permission manually when ZoneAlarm pops up with the query whether to allow the access. Naturally, I wondered whether some rogue program had somehow worked its way into Mathematica! John Fultz wrote: > No, it shouldn't.
