Carrier Grade NAT (CGNAT) or Large-Scale NAT (LSN) is used within carrier and ISP networks to enable those service providers to assign IPv4 addresses (out of their privately owned pool) to broadband subscribers and have those translated to a public IP address/port combination for packets going out to the public Internet.
Benu Networks’ CGNAT solution enables a smooth transition to IPv6 while allowing service providers to extend the breadth and life of their IPv4 networks. Carrier networks and ISPs require far more sophisticated CGNAT capabilities than consumer or small business networks.
