This setting allows you to validate IP addresses for cookie-based logins. Enable this option to deny attackers the ability to capture cPanel session cookies in order to gain access to your server's cPanel and WHM interfaces.

Select one of the following options:

1.disabled Does not validate IP addresses.
2.loose The access IP address and the cookie IP address must be in the same class C subnet.
3.strict The access IP address and the cookie IP address must match exactly. This is the default value.

Note:To use this feature most effectively, disable the Proxy subdomain settings in the Domains section of the Tweak Settings interface.
