IP addresses mean nothing, back in the days of dialup, sure because your machine was connected directly to the internet.
Unless you are still on dialup, you are most likely using a router, which means your internal addresses (the actual computers, tablets, smart phones etc), use private address space (RFC1918), which are not directly addressable unless the individual setup static NAT (network address translation) routes.. which I seriously doubt is being done.
So, all you are going to get is the outside interface of the users router, which in most cases, means all an attacker will see.. if the external interface of the router, and not much will be done (unless of course you have a really old one with known external facing vulnerabilities, and there are not too many of those, as the management interface is not accessible from the outside world, only the internal private network, unless the user explicitly enabled it.. in which case he is an idiot and deserves to be owned).

You IP address is not like your phone number.... it is already public for the most part... ISPs use DHCP, so the address will change periodically depending on the lease length configuration on the ISP side. A better analogy would be it is your address, if you want to keep it unlisted you can (in computer terms, you would be proxying or using a vpn to hide your origin).
And to prove the point.. here you go
208.86.225.146 (vps.vanbrecht.com)
74.96.213.139 (pool-74-96-213-139.washdc.fios.verizon.net)
... go have some fun
ps.. I do vulnerability assessments and penetration testing (yes yes.. go ahead and make your jokes..) for a living.. so I know what can and cannot be done with an IP. In general, just knowing it will do very little unless you are truly dumb enough to connect a computer directly to your cable/dsl bridge (router != bridge, most devices these days are all in one, back in the day you needed a separate modem/bridge and then a router).
