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. On most networks, each computer has its own IP address. An IP address is not the same as a domain name or an email address. To see the IP address of the computer you are using right now, look at the bottom of the feedback page.

To activate your subscription to Society for Endocrinology journals, you will need to give us those IP addresses which both uniquely identify the eligible machines on your network and allow access only to authorized users of your subscription. All IP addresses contain 4 numeric segments, separated by periods. A segment is either a number, an asterisk (wildcard), or a range specified by a dash (-). See example below.

Please make sure you've correctly identified ALL needed IP addresses. Those using addresses not registered will not have access to Society for Endocrinology journals.

Some institutions use proxy servers to network their environment. This means that all the IP addresses of the computers people are using appear to our server as a single IP address.
