I still don’t understand how I would be able to connect to my Plex server without having a DNS or static public IP address

Question

Before I posted her I asked AI a bit..
It told me that plex doesn’t act as the middle man by using your account, and that it instead uses NAT traversal techniques…
Now im even more confused because i know to connect to any device over the internet youd need an ip address, which changes constantly.

> it instead uses NAT traversal techniques…

NAT hole punching! It’s a super weird trick that relies on abusing how connections are established through firewalls/NAT. It relies on the fact that firewalls must allow the responses for outgoing requests back in (or it would be pointless to send requests).

Both parties connect to a third party mediator server which pairs them up and sends the other machine’s external IP and port to them. When each of them have the other party’s external address and a valid port, the old switcheroo happens: both of them send a connection request to each other. This causes the firewalls to temporarily open a path back in through that port from that IP address – just in time for the other side’s connection request to arrive.
