That 7£ /48 is a PA assignment, you can't take it home with you. https://en.m.wikipedia.org/wiki/Provider-aggregatable_addres...

You can. I have some PA address space, assigned by an LIR, that I announce out of my own AS. All "PA" means is it comes out of their parent block and, if you stop paying, they'll probably want it back.

Exactly. I have a PA /32 of IPv6 that I can sub-allocate and announce however I want. Or even lease to other people. It's my space, as long as I'm paying my LIR for it.

You can do whatever you want with that PA assignment. PA means that it's the provider's address space, not yours. You can announce it wherever you want though.

The Wikipedia explanation is flat-out wrong.

How would announcing it elsewhere help with the "Aggregatable" part? Are people accepting advertisements for small PA subnets?

Yes. A /48 of v6 is perfectly announcable.

There is no functional difference between PA and PI.
