Why might I get an 169.254.x.x address, but still get internet through that?

I was testing some ethernet jacks today to see if they could access the internet. I ended up with a few that gave me a 169.254.x.x address, but still provided internet. I didn't have internet access prior to plugging in so I'm sure it wasn't the wifi adapter and I kept checking through ipconfig, but it kept the same address.

There were a few other jacks that gave the same IP and no internet access which is what I would expect. I'm also 99% sure these jacks are hooked up to a normal network switch. Maybe I have a misunderstanding about the usage of that address space?
