About IP addresses

An IP address is the numeric address of a computer connected to the Internet. The IP address is sometimes also known as the Internet address. The IP address allows websites and routers to know where to send requested pages. On most networks each computer has its own IP address. All IP addresses contain 4 numeric segments, separated by periods. A segment is either a number, an asterisk or a range specified by a dash (-). See example below. An IP address is not the same as a domain name or an email address.


Please enter the IP addresses in the following manner:


Single address (proxy server): e.g. 123.123.123.123:

low: 123.123.123.123
high: 123.123.123.123


Consecutive ranges of addresses: e.g. 123.123.123.1-254 - 123.123.124.1-254 or 123.123.123-124.*:

low: 123.123.123.1
high: 123.123.124.254


Once you have entered all of the required IP addresses or ranges select 'I have no more IP ranges to enter'.


Please also enter a description for the IP address, this can be anything from the name of the library where the computers are located to simply 'IP address'. However, you must complete this section otherwise you will be unable to complete the registration process.

You will then be presented with a summary of your online account.
