If you then attempt to access you site from a different IP address, you will see the following message. Click the 'here' link to reset your IP address.

Choose how long you would like to authorize the current IP address you're using, then click the Authorize! button. A success message displays notifying you of the date this new IP address will expire.
The 'Active Sessions' section displays all IP addresses that have logged into your panel. Your current session is displayed in bold text. You can end any other sessions shown by clicking End all sessions except this one.
