Content Providers:

As AT&T continues to refine WAP services, we have found it necessary to revise the IP address range of the Next Generation Gateway (NGG) in our VTC data center. Please note the revised IP range for this gateway ("VTC Internet Advertised Ranges NGG") listed in red below.

Failure to open firewalls to this new range of addresses may result in a failure to connect your application or service to our network. Please configure your firewalls to allow the revised range by February 13, 2009.

For additional details, please review the updated MEdia Net Network Specifications on the devCentral Web site.
