Carrier-grade NAT (CGNAT), also known as large-scale NAT (LSN), is a type of NAT that is used by Internet service providers (ISPs) to allow multiple customers to share a single public IP address. This is done to conserve IPv4 addresses, as the number of available IPv4 addresses is limited. CGNAT introduces an extra layer of NAT between the customer's network and the public internet. While it helps alleviate IPv4 address exhaustion, it can also introduce complexities for certain applications and protocols that rely on end-to-end connectivity.
