Restrict Role Login by IP

This is a minimalistic version of Restrict By IP module .

Restrict By IP module checks for IP restriction for every user on every page load. This module instead checks for such restriction only on login.

Use this module only if you have performance concerns over validating every request against whitelisted IPs.

Unlike its parent module, this module does not allow separate whitelists per role, or per user.

What does this module provide:
Allows login for selected roles only from Whitelisted IP addresses or range of IPs. (Ex: If site admin wants the site staff to be able to login only from office premises or only via their VPN).

NOTE: Once logged in, the user can still access the site by moving outside of the whitelisted IP address. If you wish to restrict such a thing, consider Restrict By IP module.
