I was just flicking through my new android phone, ended up on my I.P address, and it had 6 addresses?!?

One IPv4
One IPv6
4 IPv6 with single colons

I might be a bit thick, but shouldn't a device have 2 I.P's at max? Or am I wrong?

Job review time,
(just a random pick from the a list).

I need professional advice. Or at least informed opinions.

I recently competed in a hackathon and won. My team wants to commercialize our idea. I'm worried that since we publicly displayed it, that the I.P. rights are a little "in the air". We NEVER verbally gave anyone the rights, and the rules of the hackathon don't even mention the words.

What would a legally savvy person do?
