Dynamic DNS use case
Dynamic DNS for VPN remote access
When a home or office VPN endpoint sits behind a changing public IP, users can lose access after the address changes. Dynamic DNS gives the VPN a hostname that keeps pointing to the current IP.
VPN endpointUse a hostname instead of a changing numeric public IP.
Remote usersKeep client profiles pointed at one memorable name.
Changing IPLet DNS update when the ISP changes the address.
Why VPNs use DDNS
VPN clients need to know where to connect. If that endpoint is on a residential or small-office connection, the IP can change unexpectedly. Dynamic DNS keeps a hostname current so users do not need a new address every time.
Common VPN scenarios
- Home VPN access while traveling
- Small-office remote access
- Site-to-site links with one changing endpoint
- Router-based VPN setups using hostnames
Typical setup
- 1. Create a hostnameChoose the name VPN clients will use.
- 2. Update the IPUse a router or client to keep DNS current.
- 3. Connect by hostnameConfigure VPN clients with the hostname instead of a raw IP.
