What is CGNAT ?

CGNAT (Carrier-Grade Network Address Translation) is a system used by internet providers to share multiple internet addresses among many customers.

Sharing an IP address can sometimes cause issues, like trouble with Backup Box, online gaming, remote access, or some apps, because the system might confuse who the data is meant for.

It's like sharing one mailbox with your neighbors—letters will get mixed up!

Why is it used by some ISP's ?

Simple. It saves money.
