In the past, I’ve posted about my DuckDNS dynamic DNS settings, and mentioned I use Dyn as well. My Dyn setup is documented below.

I should mention, however, that Dyn no longer offers free dynamic DNS (it was discontinued in 2014). They now charge $40/year for 30 hostnames.

Dyn setup

Web setup

Head over to the Dyn website and setup an account. Create a new hostname, choosing the TLD from the available options. For this setup, just click Your current location’s IP address to continue through to this process.

Go to your Account Settings page and make note of the Updater Client Key. If you don’t have one, generate one.

Router setup

EdgeOS only supports a handful of pre-configured DNS service providers by default (shown below).

ubnt@erl# set service dns dynamic interface eth0 service
afraid       dslreports   easydns      noip         zoneedit
dnspark      dyndns       namecheap    sitelutions

Luckily, Dyn is one of the providers.

set service dns dynamic interface eth0 service dyndns
set service dns dynamic interface eth0 service dyndns host-name loganmarchione.dyndns.org
set service dns dynamic interface eth0 service dyndns login username
set service dns dynamic interface eth0 service dyndns password updater-client-key
set service dns dynamic interface eth0 service dyndns protocol dyndns2
set service dns dynamic interface eth0 service dyndns server members.dyndns.org

A couple notes on the options:

  • the hostname is the entire domain (e.g., loganmarchione.dyndns.org)
  • the username is your account name
  • the password is your updater client key (that long string of numbers/letters)

Verify setup

Trigger a manual update. EdgeOS will only update the dynamic DNS provider when your IP address actually changes.

update dns dynamic interface eth0

You can show the status with the command below.

show dns dynamic status

Here, you can see the successful update.

interface    : eth0
ip address   : XX.XX.XX.XX
host-name    : loganmarchione.dyndns.org
last update  : Tue Apr 25 22:13:09 2017
update-status: good

SSL settings

Also, just so you know, EdgeOS uses ddclient for the dynamic DNS updates. The configuration file is located at /etc/ddclient.conf, but there is a directory at /etc/ddclient with a configuration file for each interface. By default, ddclient is setup to use SSL, as shown below.

root@erl:~# grep ssl /etc/ddclient/ddclient_eth*.conf

Hope this helps!
