March 9, 2009

in Microsoft, OCS

Looks like MS will be adding some new IP addresses to support Windows Live Messenger PIC & Federation.  In case you missed the original posting these changes go into effect Friday May 9, 2009 so you have some time.  If your firewall restricts access on a port by port basis then you will want to add these to your access list before the deadline.

New IP Addresses

  • 65.54.227.249
  • 64.4.9.181
  • 64.4.9.245
  • 65.54.52.53
  • 65.54.52.245

Check out article 897567 for a complete listing of IP addresses and host names.
