Abstract: 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.
