DynDNS on DrayTek Vigor: step-by-step setup
DrayTek Vigor routers offer a freely configurable DDNS client for any DynDNS2 provider via the "User-Defined" option. With DNS Beacon your network stays reachable under a permanent hostname even when your WAN IP changes. Here's how to set it up.
Step by step
- Open the admin interface of your DrayTek Vigor and go to Applications → Dynamic DNS Setup.
- Enter the values below. Your username is your account email, your password is an API key from the dashboard.
- Save the settings. Your hostname now updates automatically whenever your IP changes — usually within a minute.

- Service Provider:
- User-Defined
- Provider Host:
- api.dnsbeacon.com
- Service API:
- /nic/update?hostname=myhouse.dnsfollowme.uk&myip=###IP###
- Domain Name:
- myhouse.dnsfollowme.uk
- Login Account:
- your email address
- Password:
- your API key
- IPv6:
- IPv4 only – Customized DDNS only provides the WAN IPv4 via ###IP###. For IPv6, run the DNS Beacon client directly on the target device.
Pick "User-Defined" as the Service Provider. DrayTek substitutes ###IP### with the current WAN IP automatically; the Login Account and Password are sent as HTTP basic auth to /nic/update. Set "Determine Real WAN IP" to "WAN IP" if the router is connected directly to the internet.
IPv4 or IPv6?
The values above update the IPv4 address (A record) — the normal case on connections with their own public IPv4. For IPv6 (AAAA record) the device sends the parameter &myipv6=<IPv6> in addition or instead. How to do that on this device is in the "IPv6" row of the table.
DS-Lite or CGNAT (many cable and fibre connections): the router then has no public IPv4, and the service rejects a private WAN address with "abuse". In that case send only myipv6 — or use the DNS Beacon client directly on the target device, which detects both address families itself.
Need a free hostname first?
Create a free DNS Beacon account, add a hostname and generate an API key — then come back and finish the setup above.
