Imagine you live in a huge apartment building, but instead of each unit having its own street address, the whole building shares one main address. When mail arrives, the front desk sorts it and makes sure it gets to the right unit inside.<\/p>\n
That’s kind of how CG-NAT (Carrier-Grade Network Address Translation) works for the internet!<\/p>\n
The internet needs something called an IP address to know where to send information (like websites, videos, or emails). But because there aren’t enough IP addresses for everyone, CG-NAT lets multiple customers share a single public IP \u2013 just like an apartment building sharing one main address.<\/p>\n
