Learning Python Networking - Second Edition

NAT

This mechanism makes the traffic from the private network appear to be coming from a single valid public internet address, which effectively hides the private addresses from the internet. If you inspect the output of ip addr or ipconfig/all commands, then you will find that your devices are using private range addresses, which would have been assigned to them by your DHCP server or by your router through DHCP address dynamic assignment.

The private address ranges that are usually assigned are as follows:

• 10.0.0.0 to 10.255.255.255
• 172.16.0.0 to 172.31.255.255
• 192.168.0.0 to 192.168.255.255

The idea is simple: make computer networks use a range of private IP addresses and connect to the internet using a single public IP address. Thanks ...
