Do police really catch a hacker if you have their ip address?

[027]

What is the use of having the ip address of a hacker? Many ask what next, which means, its useless having the ip address of a remote hacker. Has anybody tried going to the police with the ip address just for hacking?
Here is the ip address of my Indian creep, 117.212.37.121, who keeps hacking my account. He has BSNL connection, and is from Bengaluru.

well how many hackers have been caught? not alot at all. when trying to track down a hacker, the trackers need to bypass the ip adress to get the location but out of a 75million other streams on the internet, its really hard to know what stream the fish is in.

Tracking a hacker is like trying to find a single piece of salt in a 10pound bag of sugar. having an ip adress only means nothing, it can lead to over 1000 or even a million different locations and which tracker is going to go knocking on millions of doors? lol none really unless you higher a pro hacker to hack the hacker.

The police can use the IP address to figure out whose Internet connection the hacker or proxy server was using and the address of the area that the Internet connection serves. So if the hacker was at home at the time of the crime, they can use the IP address to determine either that he or she was in his or her neighborhood, or he or she used a proxy server.
