This is included at no cost.
IP Account Lock works at the account level to let you determine which computers or computer networks are able to access your domain account. Found in your Account link under Security, this advanced feature shows you any current addresses that are allowed and provides means to add new ones. After you log out, your next login attempt can only be made from one of the registered IP addresses. When used with the 101domain VIP Security Card, you gain superior protection for your account.
Good for limiting employees to log in from the office and not from home, allowing access to only your trusted network(s), or preventing someone from gaining access through your computer on an untrusted network or public wireless network.
Note: Only works for STATIC IP Addresses. If you have a DYNAMIC IP Address, you will not be able to use this feature. If you are unsure of your settings, contact your internet service provider.
