What is IP Recognition?
IP recognition is an authenticating process that some websites use to filter out unwanted users. The IP address is usually expressed in dot notation, e.g. 128.121.4.5. The address can be split into a network number (or network address) and a host number unique to each host on the network and sometimes also a subnet address. Institutions such as libraries or corporations with many terminals operating on one site usually have an IP range. To find out what is the IP range of your institution contact your IT department.
