How do I adjust account IP addresses?
Last updated on October 19, 2021
The Admin Tool allows you to adjust your Account's IP addresses. You can edit, remove, and move an IP address range, and split IP address ranges into subsets yourself on the tool.
An IP address is the logical address of a network adapter. The IP address uniquely identifies computers on a network. An IP address can be private, for use on a Local Area Network (LAN), or public, for use on the Internet or other WAN. IP addresses can be determined statically (assigned to a computer by a system administrator) or dynamically (assigned by another device on the network on demand).
IP addresses consist of four bytes (32 bits). Each byte of an IP address is known as an octet. Octets can take any value between 0 and 255, but various rules exist for ensuring IP addresses are valid.
As an administrator or librarian, you are unable to add an IP address range to your account, but you can request for customer support to adjust your account IP addresses. Please contact us via the Email option at the bottom of this page using the following template:
Dear Elsevier Helpdesk,

[List IPs below or attach a document]
IP xx.xx.xx.xx
IP xx.xx.xx.xx
IP xx.xx.xx.xx
IP xx.xx.xx.xx
On behalf of [ORGANIZATION NAME], I [your full name] as a duly authorized representative confirm that the above IPs are assigned to our organization.
I acknowledge that these IP’s will be subject of the terms of our currently active subscription agreement with Elsevier.
Would you please kindly add these IP’s to our organization’s account?
With kind regards,
[Your name]
Please note:
- Requested IPs need to be exclusively dedicated to your institution.
- The following IP ranges cannot be added because they are private IP addresses:
- 10.0.0.0 --- 10.255.255.255
- 172.16.0.0 --- 172.31.255.255
- 192.168.0.0 --- 192.168.255.255
You can edit account IP address ranges on the ‘Edit Account IP Address Ranges’ page. This page displays all IP address ranges assigned to Groups of an Account. You may move, split, remove, or request new IP address ranges for all groups from this page. To use one of the functions, first select an IP address from the Account’s Group list.
Each Account may contain its own network of related Groups, and each Group may be assigned an IP address to allow the Account users to access the entitlements.
Group level Administrators viewing this page at the Account level will only see the IP address ranges that belong to their Group.
A Group may have more than one assigned IP address range.
Consortium, Account, and Group Administrators can remove an IP address range from a Group.
Note: This action will take effect immediately. To retrieve a deleted IP address range and restore it, you should use one of the contact options below to request that the range is restored by our Support team.
Follow these steps to remove an IP address from a Group:
- On the ‘Edit Account IP Address Range’ page, select a check box next to the IP address to be deleted. You may select more than one IP address.
- Click ‘Remove’. The ‘Remove IP Address Ranges’ Confirmation page will display the IP address ranges to be deleted.
- Click ‘Confirm’ to remove single or multiple IP addresses from a Group or click ‘Cancel’ to return to the ‘Edit Account IP Address Range’ page.
An IP address range used by a Group can be split into smaller ranges, which can then be moved from the Group to a different Group, removed, or split further.
Note: Splitting an IP address range takes immediate effect.

Follow these steps to split an IP address:
- On the ‘Edit Account IP Address Ranges’ page, select the IP address range that you would like to split.
- Click ‘Split into subset’. The ‘Split IP Address Range into Subsets’ page will display. This page displays the IP addresses you have selected and provides you with two options:
Option 1 |
To split the IP automatically, the Admin Tool calculates how many subsets will be generated and then splits a selected IP Address range. If you select to automatically split an IP address range, the ‘Confirm Splitting of IP Address Range’ will display. |
Option 2 |
To enter a specific IP address to isolate is based upon your selection of an IP range format followed by the Admin Tool providing the remaining IP address ranges after the split. |
To select an IP address format:
- From the ‘IP Address Formats’ list, select an IP address format to base your IP address split.
- You can then do one of the following:
Click ‘Previous’ to return to the ‘Split IP Address Ranges into Subsets’ page.
Click ‘Next’ to advance to the ‘Split IP Address into Subset – Values’ page that lists the IP address that you wish to split.
Click ‘Cancel’ to return to the ‘Edit Account IP Address Ranges’ page.
To enter an IP address to split:
- In ‘Enter IP Address to split…’, enter the values to base the new IP address on.
Note: Each IP address range box must contain a number between 0 and 255, and the new IP address range must be within the IP address range you are splitting. - You can then do one of the following:
Click ‘Previous’ to return to the ‘Split IP Address Ranges into Subsets – Template’ page where you can select the format for the IP address to be split.
Click ‘Next’ to advance to the ‘Split IP Address into Subset – Confirmation’ page.
Click ‘Cancel’ to return to the ‘Edit Account IP Address Ranges’ page.
