Dial-up modem users
If you are connecting to the Internet using a modem, each time you connect to the Internet, you’ll be assigned an IP address that’s available. Although you may get the same IP address as a previous connection, often you’ll be assigned a different IP address each time you connect. If you want a static (address that doesn’t change) IP address, you’ll need to connect to the Internet using a broadband connection.
Broadband users
Unlike a dial-up modem, when connecting to the Internet with broadband, you are given a static IP address that will be the same each time. However, this address can still change, below are a few of the reasons why this may change.
- Your DHCP lease time given to your IP address has expired.
- Your ISP changes their network infrastructure. Causing how IP addresses are assigned to change.
- ISP changes the center or router responsible for your address.
- ISP has encountered a network failure causing routing tables to rebuild or other network related issues.
