CGNAT is a method used by internet providers, like Belong, of sharing a single unique public IP address with multiple users. This allows them to access the internet without interruption.
Why would you use CGNAT?
We're running out of IPv4 addresses, and are planning on moving all our customers over to IPv6 addresses. Until we get there, though, we’ve decided to use the CGNAT method as it has the least impact on a majority of Belong customers.
What this means for you
This means your modem or router will use a private IP address, but when you access the internet, we’ll transfer you across to a shared public IP address.
While this won’t affect most of our customers, there’s a small group it might affect; customers who use services that depend on NAT (Network Address Translation) and could include:
Web, email and file servers
Security cameras, printers and some home automation
Remote access to computers or devices
