DynDNS on Aruba Instant: step-by-step setup
Aruba Instant access points support Dynamic DNS profiles with a custom update URL. With DNS Beacon your site stays reachable under a permanent hostname even when your WAN IP changes. Here's how to configure the DDNS profile.
Step by step
- Open the admin interface of your Aruba Instant and go to Configuration → Services → Dynamic DNS.
- 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.

- Provider:
- DynDNS
- URL:
- https://api.dnsbeacon.com/nic/update?hostname=<h>&myip=<a>
- Hostname:
- myhouse.dnsfollowme.uk
- Username:
- your email address
- Password:
- your API key
- IPv6:
- IPv4 only – Aruba Instant On does not support DDNS with IPv6. For IPv6, run the DNS Beacon client directly on the target device.
Aruba Instant (ArubaOS 8.x+) supports custom Dynamic DNS profiles. In the Web UI or via CLI (`dynamic-dns` / `ddns-profile`), set the provider to "DynDNS" and override the URL so updates go to the DNS Beacon API. Aruba substitutes <h> with the hostname and <a> with the current IP.
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.
