How to keep my Dedicated IP unchanged when renewing my service?
If you wish to keep your current dedicated IP unchanged, then you have to purchase next VPN period at anytime before the date when your Dedicated IP VPN service expires. For example let's say that your Dedicated VPN service expires on 2009-09-10. So you can log in to the Members Area anytime before this date and make a purchase of next period (31, 93, 186, 365 days). The new VPN period will continue to your currently running period (it will start from 2009-09-11), so you will not loose any day of your VPN service and IP address will remain assigned to your account.
In case that your VPN service would expire without any purchase of next period, then your currently used Dedicated IP will be freed for the other users.
