A VPN server address is the hostname or IP address a remote user enters to reach a virtual private network gateway. It tells the VPN client where to build the encrypted tunnel before authentication starts, and it is often saved in client profiles or setup instructions.
In cyber security, this detail matters because it helps point a user to the correct access point and can also help attackers impersonate one. Phishing pages and fake support portals may ask for the server address along with usernames and passwords, then use that information to make credential-harvesting look more believable or to identify the real VPN target. Defenders reduce this risk with phishing-resistant MFA, verified bookmarks, and user training that emphasizes checking the full domain before entering any access details.
