What are the differences between public and private IP addresses? Public IP addresses are registered on the internet. It’s what gives you access to the world wide web. Private IP addresses are not publicly registered on the internet. So you can’t access the internet using a private IP address.

From someone that had little to no knowledge regarding the topic, this has been rather educating. Thank you!

A few points. Some ISPs hand out private addresses, which mean customers are already behind NAT and so cannot connect to their own network from elsewhere. NAT also breaks some protocols. Also, address classes are obsolete, replaced with classless addresses, where a base address and subnet mask are specified.
BTW, according to Vint Cerf, the guy who invented this, 32 bit addresses were only intended to be used for proof of concept, with the final version having a much larger address space. Unfortunately, IPv4 escaped, leaving the world trying to get by with only 32 bits addresses.

This is an extremely helpful video. I work in IT and regularly get questions from clients about their employees'/family members' internet activities. I do the best I can in explaining public/private IP addresses in layman's terms and will supplement my tutorials with this video in the future.

I am taking the cisco courses and thanks to you it all becomes clear and easy to connect the dots, most of all no waste of time but right at the point.

I have looked for many explanations on IP addressing. This is by far the best!

[gwgux]

A couple things:
Most Linux computers these days use "ip a" to get their ip address instead of "ifconfig". The old command can be installed, but is not always there by default. Also, at some point you may want to do a video on specific IP addresses used for multicast, loopback, and broadcast if you haven't done so already.
