The dedicated IP server is a VPN server just like other servers. It just has an additional feature - you can order a dedicated IP address for an additional price and you will be the only person using the assigned IP address.
We offer dedicated IPs in the United States (Buffalo, Dallas), Germany (Frankfurt), United Kingdom (London) and Netherlands (Amsterdam). The dedicated IP in any of these countries costs $70. The price is for one year. Of course, you need to have a valid VPN account to benefit from the dedicated IP (dedicated IP will not work without a valid VPN account).
We recommend to test US #323, 837, 838, Germany #70, UK #46, 89 and Netherlands #15 servers - that’s where dedicated IP addresses are assigned.
