One of the features you may have seen is the offer of a Dedicated IP.
VPN providers can have millions of customers but may only have a few hundred or thousand servers.
Obviously not all VPN users are active at once, but there are still way more users than servers.
This creates an issue where each user must share a server and IP address with many other users.
This comes with some potential advantages and disadvantages.
As such it doesnt take too long for VPN servers to be identified and blacklisted from the web link.
Getting a dedicated IP address means that no other users are using your assigned IP address.
If youve got a dedicated IP address from your VPN provider, you dont need to worry about this.
As youre the only one using the IP address, there are no suspicious patterns of activity.
Cost
Unfortunately, dedicated IP options will cost money.
Partly this is a standard business decision to charge you for an extra feature.
