4. Server address
The server address is a fundamental element within Virtual Private Network configuration on iOS, representing the destination endpoint to which the device establishes a secure connection. It is essential for directing network traffic through the VPN tunnel, ensuring data protection and anonymity.
-
IP Address or Domain Name
The server address can be specified as either an IP address (e.g., 192.168.1.1) or a domain name (e.g., vpn.example.com). A domain name offers the advantage of abstraction, allowing the VPN provider to change the underlying IP address without requiring users to update their configuration. The domain name is resolved to an IP address by DNS servers. For example, a mobile workforce relies on a consistent VPN connection to access internal resources. If the VPN server’s IP address changes due to maintenance, using a domain name ensures uninterrupted connectivity without requiring device reconfiguration.
-
Importance of Accuracy
An accurate server address is imperative for establishing a functional VPN connection. An incorrect address will result in the device being unable to connect to the VPN server, preventing secure tunneling. Manual configuration errors are a common source of connectivity problems. For instance, a single mistyped digit in the IP address can prevent a user from connecting to their corporate VPN, hindering their ability to access essential work resources.
