This safety feature restricts the IP addresses used by the administrator user at login.
When no IP address is entered, administrator users may login to ADAMS from any IP address. When at least one IP address is present, administrator users can login to ADAMS only from one of the addresses present.
Clicking the link shown on the IP address restrictions page brings up the following pop-up window:
You can enter an actual IP address in the textbox, or click my IP to generate your current IP address. A slash and a subnet mask (by default "/32") will be automatically generated if not entered.
You should consider entering all IP addresses from which your administrator username(s) normally login to ADAMS, including wireless networks if any.
Please use caution when planning to use ADAMS in other venues (for example, when you anticipate that your administrator will log in abroad during special events) as a missing or incorrect IP address may keep them from using ADAMS in different locations.
If, after defining a list of IP addresses, you are unable to login as an admin user from a different location, the following error message will be displayed on the ADAMS login page:
Should this condition occur and you cannot login from one of the defined IP addresses, please contact the ADAMS Help Desk to assist you.
You may use your favorite search engine to find out more about IP addresses and subnet mask. To illustrate this, in a nutshell:
- Entering a subnet mask of /24 (first 24 bits) would allow logins from hosts 1 to 254 of the first three decimal octets. For example: entering "18.104.22.168/24" would allow logins from hosts 22.214.171.124 through 126.96.36.199.
- Entering a subnet mask of /32 (all 32 bits) would allow logins only from the specified IP address. For example: entering "188.8.131.52/32" would strictly all admin users to login from IP address 184.108.40.206.
