Lot's of very useful information to solve your problems as far as dealing with many of the typical problems and some not so typical problems that we run into when working on a computer.
If you use a home router to connect to the Internet, the IP address shown will be the address of your router or company's proxy. Your IP Address - Internet Protocol Address is a specific number that identifies your computer and allows it to communicate with other computers and devices on a computer network.
This is your computer's address.
A dynamic IP Address is not static and could change at any time as it is controlled by your ISP or it is used for running a DHCP (Dynamic Host Configuration Pool) server. This typically could be used for dial-up, wireless and also high speed connections. Every time you dial up or log on, you get q new IP, for that time you are logged in or on-line. When you connect to the internet through your ISP (internet service provider) such as AOL, etc., or a Local Area Network (LAN) connection, you are assigned an IP address.
This address identifies your computer from the other computers on the internet.
Static IP Address always stays the same.
