IBM Connections Cloud is changing IP ranges again

IBM announced that IBM Connections Cloud will be adding new IP ranges and sunsetting previous ones. Here is the announcement

IP Address Changes in February 2015
Action required if your firewalls require IP addresses!


On or after February 07, 2015, IBM will be adding several new IP address ranges to the network supporting the Connections Cloud and SmartCloud Notes services in our United States based data center. We plan to transition to these new ranges, sunsetting some of the current ranges at a later date.

This change will not impact clients who are accessing our services as recommended by using our public DNS names (eg. apps.na.collabserv.com) and is specific to services in our United States based data center.

Clients who utilize firewalls requiring IP addresses, private DNS, or who otherwise filter based on IP addresses are urged to contact Brad Ralphs (ralphs@us.ibm.com) or IBM Connections Cloud Support (support@collabserv.com) to ensure you have the full, current list of required addresses inclusive of those being put in place on or after February 07, 2015.

Seems kind of important for you to know since most enterprises block or restrict ranges. Or need to update DNS cache
