Facebook's public IPv6 address.

Notice the face:b00c?

That's pretty awesome :D (I wonder how much they've had to pay for that hehe)

Wow, no kidding 🤑

Yeah that's neat. thing is I don't think they even had to pay for it cause they were one of the first adopters they probably just kept disassociating and reconnecting until one of them showed face. script wise it wouldn't be that hard to do but I wouldn't do it unless you want to tick off your isp

Whatsapp is the same. I believe the have a /32 ipv6 pool, they can chose any ip in their authoritative name server to be resolved
