what is a static ip used for
Static and Dynamic IP Address Properties. As the name implies Static IP addresses are the same every time you connect or send a message. Static IP Addresses are used by all major web sites, email services, FTP services and so on. There are no exceptions to this. You will, however, pay handsomely for static IP addresses. Dynamic IP addresses may change each time you connect to the Internet or even, in extreme cases, every time you send a message. Dynamic IP addresses are the normal customer access method used by most ISPs or Service Providers.
