Intresting.
IP stands for Internet Protocol
Depends on whose has your IP
Lets says. a Bad Guy has your IP, a Hacker or some miscreant
Then can possibly steal your data, break in2 your computer. Install Ad-ware , Spy-ware
and install Key-loggers(software which notes every keys types and mails it back to the hacker)
So the bad guy can do lotta things if he has your IP
and say your friend of any-1 has your IP, who letz assume as a good guy. Then you can Share files .. which is called P2P (Peer-2-peer) and Play Cool Board Games via internet and lotta nice stuff
The next question is, whether you have Static IP or Dynamic IP.
Static IP is a IP, which once assigned to your Computer by your ISP will be same all the time.
Dynamic IP is one, where your IP changes everytime you LOGON to the internet
Most of the ISP's provide Dynamic IP, which has several advantages compared to STATIC IP. if your ISP provides one. You can surely OPT for Dynamic IP
