Each time that you connect to the internet, your provider will generally provide you with a dynamic IP address that is valid while connected or for a period of 24 hours. This tutorial will show you how you can have a fixed IP address that corresponds to your computer name when your provider issues you with a dynamic address. This means that you will actually have two 'addresses', the dynamic that is issued to you and your personalised 'fixed' one. This new address will be permanent and will automatically update each time your dynamic address changes. You can also host a web or FTP server using this method without any problems.
