Disclosed herein are system, method, apparatus, and computer program product embodiments for dynamic mitigation of CGN IPv4 address provisioning for network gateways when adverse conditions are in effect. A network gateway may be provisioned with a shared WAN IP address from a pool of IP addresses designated for Carrier Grade Network Address Translation (CGN) and configured to detect the occurrence of an adverse condition for a connection provisioned the shared WAN IP address. Upon detecting an adverse condition, the network gateway may send a request for a new IP address to a DHCP server configured to recognize flags indicating an adverse condition. The DHCP server may then provision the gateway with a new public IP address.

Mitigation of carrier grade NAT

Disclosed herein are system, method, and computer program product embodiments for identifying a geographical location of an issue in a broadcasting network. An embodiment operates by a server or a headend sending a diagnostic test to a set-top box capable of processing a channel. The diagnostic test informs the first set-top box to have an idle tuner tune to the channel and to determine a performance characteristic of the first set-top box in processing the first channel. After receipt of the performance characteristic, the server or headend performs an analysis of the first characteristic and determines whether there is an issue in the broadcasting network. If there is an issue, the server or headend identifies a geographical location of the issue in the broadcasting network and sends the geographical location to a user for resolution of the issue.
