To use this feature, you need to be registered as your organisation's Account Administrator and have logged in.
To give members of your organisation access to the journals you have subscribed to, you need to supply the IP addresses that identify the eligible machines on your network. From the 'Account Administrator Links' drop-down menu, click on 'Configure IP Address' to take you to a new page where you can enter new IP addresses and make changes to your existing IP configuration. However, please note that if you are part of a consortium or license agreement with us you will need to email email@example.com to set up or amend your IPs.
Adding, deleting and excluding IP addresses
If you want to add a single IP address or range, enter it into the first text box and click 'Update' at the bottom of the page. If you want to add more than one IP address or range, use the second, larger text box and enter the IP addresses or ranges with a comma (,) between them. Click 'Update' to make the changes.
All of your existing IP addresses or ranges are displayed on the page. If you wish to delete any of these, check the 'Delete' box that appears next to it/them and click 'Update'.
If you wish to exclude any of your listed IP addresses from within ranges, tick the 'Exclude' checkbox and click 'Update'. You can also enter any IP addresses you wish to exclude in the first textbox, tick the 'Exclude' check box next to it and click 'Update'.
IP addresses are made up of four numeric components separated by a full stop (period). Each numeric component ranges from 0 to 255. You can express an IP range by using a hyphen (-) and you can use a wildcard within a range by using an asterisk (*).
About IP addresses
Examples of valid IP address formats (note the numbers are used as examples only):
- 18.104.22.168 = a single IP address
- 121.18.19.* = all IP addresses beginning 121.18.19
- 22.214.171.124-255 = a range of IP addresses from 126.96.36.199 to 188.8.131.52 inclusive (ie the same as the example above)
- 121.18.* = all IP addresses beginning 121.18
- 121.18.0-255. = all IP addresses in the range 121.18.0-255 (ie all addresses beginning 121.18)
- 121.18.0-255.0-255 = all IP addresses beginning 121.18
- 121.* = all IP addresses beginning 121
- 121.0-255.0-255.0-255 = all IP addresses beginning 121
CIDR IP addresses: Cambridge Journals Online now also recognises CIDR (Classless Inter-Domain Routing) IP addresses. CIDR is a new convention for IP syntax which means that a single IP address can designate multiple IP addresses. A CIDR IP address looks like a conventional IP address except that it ends with a forward slash followed by a number called the IP Network Prefix. You can enter CIDR IP addresses in the appropriate boxes as described above.
