Every device connected to the public internet is assigned an IP address. It's like a phone number for each device. To be able to connect to the internet, each device needs such an address.The term "dynamic IP address" means that when a device connects to the internet, it's given an IP address taken from a pool of available addresses. While it's possible to get the same IP address on multiple connections, generally, each time you connect, you'll get a different address.If you want to hide your address from the web applications you're connecting to; you'll want a VPN service that provides dynamic IP addresses. In our directory, we list the number of IP addresses each service offers. By using a service with more available IP addresses, the chances of you getting a repeated IP are quite small.There are some minor disadvantages to using a dynamic IP. If someone who previously had the IP address you've been assigned did something nefarious on a service you use, the IP address might be banned. Usually, VPN providers are cautious about checking their IP addresses against blacklists, so the chances of this being a problem for you are slim.By contrast, a static IP address is an address that's assigned to you and only you. Most often, this is needed if you're running a server. Usually, static IP addresses are used in corporate situations and are generally not practical for general remote access, like from a hotel or coffee shop.Unless you have a specific application that you know needs a static IP, you'll want to be assigned a new dynamic IP address for each VPN session you initiate.
