Why static ip use

The main reason for having a static IP address is that you can only use SSL encryption (the stuff that makes e-commerce happen) on a static IP address. In order for a person to transmit sensitive data over the internet at times this data must be encrypted to prevent someone from intercepting the information. You can only use this encryption (called SSL) when the web site has its own IP address (static IP). It doesn’t work on a shared IP. So when takes in order with a person’s credit card it needs to encrypt this data and it uses SSL with its static IP. Another reason for having a static IP address is that if a web site wanted to have anonymous ftp transfers (basically where anyone can download files off a site) the site needs to have a static IP address to handle the anonymous ftp transfer. Other than these two reasons there is no need for a site to have its own IP address.
