[AG-TECH] [Fwd: Argonne bridge machine IP change 1/26]

[Thomas D. Uram]

The Argonne bridge machine has now been moved to its
new IP address.  It will take some time (perhaps as long
as two days) for the new IP address to propagate over
DNS. 

Please update your firewall rules accordingly, if you had
configured for the earlier IP address (which was 140.221.9.16).

If you have any questions, let us know.

In order to provide better multicast service to the Argonne bridge machine,
the machine will be relocated to a different segment of the Argonne network.
The hostname of the Argonne bridge machine is milton.mcs.anl.gov. 
Currently, the IP address of the host is 140.221.9.16.  On Friday,
January 26, at 6pm, the machine will be moved to the new network
segment, where it will have the IP address 140.221.34.12. 

If you rely on the Argonne bridge, you may have to update your firewall
configuration to allow traffic from the new IP address.  If you're not sure,
share this information with your network administrators.  And a general
note:  information about the hostnames and port ranges used by bridges
can always be obtained in the VenueClient by selecting Tools->Preferences,
then Network.

If you have any questions about this move, please ask.
