NAT vs PAT, Static vs Dynamic -- demystified! -- Network Address Translation

If you've read anything about NAT, you've likely come across these terms: Static NAT, Static PAT, Dynamic NAT, Dynamic PAT. These terms are made up of two sets of two terms: Static vs Dynamic, and NAT vs PAT.
In this lesson, we simply and clearly illustrate and explain what each of these terms mean, so that you have a clear idea of what it means when you combine them.

[@traktion9]

Question, why have a range of IPs to translate out to? We have dozens of devices behind our home router which all use the same 1 IP even if they're all using port 80 for the web. As I understand it NAT knows the difference for which host sent a port 80 destined packet by assigning different return ports. Isn't this adjusting the layer 4 header making it a PAT in reality?

[@PracticalNetworking]

The type of translation your home router is doing is a Dynamic PAT. Details here: kzbin.info/www/bejne/aKWbXoqIj7x2p5o

[@ayradizem2770]

Thank you

[@PracticalNetworking]

You're welcome, Ayrad!

[@hoppingturtles]

Wow, did not know that dynamic NAT existed. So you're telling me I can choose which public IP address I want my computer (behind a router) to take? So my router can essentially have many IP addresses associated with it?

[@PracticalNetworking]

If you control the Router, then yes, you can choose the IP. You'll have to consider Routing (meaning, if you use IP you don't actually own, the traffic won't actually be directed to you).

[@CCNABatais]

ausome 👌

[@davidsmithson7806]

I thought PAT uses the same Public IP address but just assigns different port numbers to the devices using the IP address?

[@PracticalNetworking]

Yes, you're thinking of Dynamic PAT =) Details here --> kzbin.info/www/bejne/aKWbXoqIj7x2p5o

[@tsap0015]

Sorry I am a complete newbie. Why those layer headers need to be modified? (around [1:31])

[@PracticalNetworking]

That's explained in the previous video of the series: kzbin.info/www/bejne/eJjXgIWBd5WfotU

[@LulzChicken]

You rock.
