挂vpn后dns

"挂vpn after DNS" refers to a method of configuring a VPN using DNS to determine the IP address assigned to it. The process involves ensuring that the assigned IP address does not fall into a restricted network by checking against DNS records. This method provides a more flexible and secure alternative to traditional VPNs, allowing the VPN to connect to a domain without falling into restricted networks, thus bypassing IP filtering or managing traffic through different networks.
