Dynamic DNS
Keep a changing address up to date, without a third-party service.
Dynamic DNS lets a device update a record when its public address changes, for example a home router or a gateway on a residential line. Patchvia DNS runs the update endpoints itself, so the record stays under your control.
Per-zone tokens
Create a dynamic DNS record in a zone and the console issues a token for it. The token is shown once, so copy it into the device before you leave the page. Each token can only update the record it was created for.
Protocols that devices already speak
The server accepts update requests in the formats that common routers and gateways send, so most devices work without custom software. The TTL for a dynamic record is set when you create it and can be changed later, between one second and one day.
Current limits
Dynamic updates authenticate with the per-record token. TSIG-signed dynamic updates are not supported yet.
Set up a dynamic record
Create a record for your home address, then point the router’s dynamic DNS settings at this server.
