Domain Blacklist: Block specific email domains, preventing users from registering or logging in with email addresses associated with those blacklisted domains.
IP Blacklist: Block access to the entire website by blacklisting specific IP addresses. Users with blacklisted IP addresses will receive a message stating that access is denied when attempting to visit the site. This feature is highly efficient and should be used carefully because it can block access for all users, including administrators, if their IP address is among those listed in the blacklist.
IP Whitelist: Whitelist certain IP addresses, giving them priority over blacklisted IP addresses. If IP addresses are added to this list, only admin users with matching IP addresses will be able to access the admin panel. If the list is empty, there will be no restrictions for any assigned administrators to access the admin panel.
