sshr

sshr DDNS

Dynamic DNS on dyn.sshr.uk

Create a hostname on dyn.sshr.uk, then update its IPv4 A record with a token URL from your router, NAS, or any small client.

Create a hostname

Pick a short label like home-lab. If you leave it blank, sshr generates one for you.

Update from a client

curl "https://www.sshr.uk/api/ddns/update?hostname=home-lab.dyn.sshr.uk&token=YOUR_TOKEN"

If you omit ip, sshr uses the caller IP. You can also send &ip=1.2.3.4 or &myip=1.2.3.4.

Notes

  • Only IPv4 A records are supported in this first version.
  • Each hostname uses one label under the delegated zone.
  • Record creation is limited to 20 requests per minute per IP.
  • Record updates are limited to 120 requests per minute per IP.
  • Records that are not updated for 60 days are deleted automatically.
  • The update token is the only credential for changing a hostname. Keep it private.
