Web Security
Accessing the Internet is a security risk.
When you are connected to the Internet, an IP address is used to identify your PC. If you don’t protect yourself, this IP address can be used to access your computer from the outside world.
A fixed IP address is a larger security risk.
If you’re using a modem with a dial-up connection, you will get a new IP address every time you connect to Internet, but if you have a fixed Internet connection (cable, ADSL, fixed line), your IP address will never change. If you have a fixed IP address, you give potential Internet crackers all the time they need to search for entrances to your computer, and to store and share (with other crackers) information they might find about your unprotected private data. -Source
