IP stands for Internet Protocol. Every computer on your institution's network will have a unique IP address. IP addresses are represented by a series of four numbers (bytes) each separated by a full stop (period). Each number can be anything from 0 to 255.
The Internet Assigned Numbers Authority (IANA) has reserved the following three blocks of the IP address space which may be used for constructing 'private internets', i.e. networks which are strictly local to an organization and whose traffic is not routed over the global Internet. Any network using private addresses must not be directly connected to the Internet but must rather be linked to it by some device capable of address translation: such a device will hide the individual hosts on the private network from the Internet. A host cannot send an IP packet to a private address unless it is on the same private network as that address.
10.0.0.0 - 10.255.255.255
172.16.0.0 - 172.31.255.255
192.168.0.0 - 192.168.255.255
The block 127.*.*.* is reserved for local software loopback testing
127.0.0.0 - 127.255.255.255
The block 224 - 239.*.*.* is reserved for IP multicasting
220.127.116.11 - 18.104.22.168
The block 240 - 255.*.*.* is reserved
240.0.0.0 - 255.255.255.255
Addresses from within these ranges must not be visible from the global Internet. You must not use addresses from within these ranges when entering your own details.
Some institutions gain access to the Internet via a server which is not on their site. These servers are known as 'proxy servers'. If your institution uses a proxy server, you will need to by-pass it in order to get access to our online journals. The same can apply if your institution uses a firewall.
There are some exceptions. If the proxy server or firewall has been set up to service your institution or department only, you may be able to get access to the online journals without by-passing it.
Your Computing Officer/IT Department should be able to tell you whether your institution uses a proxy server/firewall and, if so, how to bypass it. If not, please contact OUP Journals help desk.
After adding an institutional subscriber number to your Oxford Journals account, you will be taken to an Institutional Details screen where you will be asked to enter your IP addresses.
If you are returning to your account and wish to update your IP details select 'Institutional Details Edit' from the main Details and Subscription page.
Simply add your IP address in the box provided and select 'Update'
You can add up to 100 IP addresses in this way.
To enter a range of IP addresses:
Click on 'Edit IP addresses'. Enter the IP addresses as a range. You can enter up to 40 ranges.
IP(1): 192.168.12.35 - 200
IP(1): 192.168.12 - 14.*
Once you have finished entering your IP details, select 'Continue' to return to your Details and Subscription page
Note: The IP addresses given in the instructions above are for example only and you must not use them when entering your own details. Please contact your Computing Officer/IT Department for the IP addresses of the computers at your institution.
Sometimes a range of IP addresses may be represented by using a *. The * is used to represent any number between 0 and 255 and is known as a 'wildcard'. For example, 192.168.13.* would represent a range of IP address from 192.168.13.0 to 192.168.13.255.
Wildcards can also appear in the third position (byte) of the IP address. For example 22.214.171.124 would be entered as:
You may be given a range of addresses where the number (byte) in the first or second position is variable.
For example, 127.12-14.*.*. This would need to be entered as shown below:
If you need to block certain IPs from your range, then rather than using wildcards to enter the entire range, you should enter sub-ranges of IPs and omit those that you wish to block.
For example you would need to enter:
IP(1): 129.10.1 - 9.*
IP(2): 129.10.11 - 255.*
to block 129.10.10.* from your range, rather than entering 129.10.*.*
