So every time you join a new network, your IP in the others can change?

No, only once if there is a collision, which is 1/4M

That's a "yes"

NO. You will ONLY have to rotate your IP if you join a network in which there is a collision. 1 in 4 million chance. If that happens, it's ok. Ideally you are using magicDNS and don't have to worry about IPs or just use the IPv6.
