A static IP address is an address that does not change over time unless changed manually. It is used when you need the IP address or network location to remain the same consistently. A good example of this is for a web server.
If you go to www.google.com you are really going to the IP address of 66.102.7.99.
If this were to change suddenly you would not be able to get to Google unless you knew the new IP address or until Google updated their DNS records.
A Dynamic IP address is an address that keeps on changing. It is mostly used when having a consistent
IP address is not necessary. An example of this would be the IP address your ISP (internet service provider) assigns you when you log on to the internet. You must have an IP address to surf the web but once you disconnect you loose that address. Then the next time you sign on you are assigned a new one. This is done using DHCP.
