If you have a specific question about VPNs or international IPs,feel free to ask!

VPN (Virtual Private Network) is a software tool that allows users to connect to the internet from a remote location while controlling access to the internet. It is commonly used for remote work, video conferencing, and other online activities that require a private network. The VPNs you mentioned are types of software applications that enable users to access the internet over a private network, often for purposes such as remote work, video conferencing, or online gaming. If you're asking about international public IP addresses, it refers to the use of public IP addresses for the purpose of connecting to the internet over a private network, rather than using a public IP address directly. For example, NordVPN uses a private tunnel over a public IP address, while Bitly uses a private tunnel over a public IP address. If you're asking about international private IP addresses, it refers to the use of private IP addresses, such as those used in VPNs, to access the internet. These private IP addresses are often used to control access to the internet over a private network, such as a VPN.
