CGNAT FAQ – IPv4 Conservation and IPv6 Migration
By contrast, IPv6 addresses are in a 128 bit format. This allows for 340 undecillion numbers. How many is that? It’s 340 followed by 36 zeros. That’s enough to give an IP address to every atom on the surface of the earth and still have enough left over for 100 more earths.
The majority of Internet content is currently available only for IPv4, but all those billions of new devices that are coming will be given IPv6 addresses. So while everyone is waiting for IPv6-based content, your IPv6-only users with those billions of devices will still need to access that IPv4-only content. It won’t be the content providers your subscribers are angry with, it’ll be you. CGNAT provides seamless communication between IPv4 and IPv6 devices and networks.
Also, networks often require different transition technologies to be deployed simultaneously. These solutions allow you to deploy each transition technology concurrently. For example, you could start with CGNAT to immediately mitigate IPv4 address exhaustion, and then phase in NAT64/DNS64 to enable IPv6 clients to access the IPv4 Internet when you are ready.
