No-IP with Raspberry PI

We're gonna be setting up a DDNS service with automatic updates from our RaspberryPi!

No-IP service at, provides up to 3 hostnames for free. The only caveat is that they need to be confirmed every 30 days, for a small fee all those limitations are lifted.

Register a new account (or use your existing one) and setup a new hostname under the hostnames section. Once this is done come back here and we're gonna setup automatic updates!

SHH into you RaspberryPi and let's get started. (You can do a new installation following the guide here.)


I like to use VIM to edit files, which doesn't come by default with
Raspbian Stretch Lite.
Type the following to install it:
$ sudo apt-get install vim

Feel free to use whatever editor you know and it's comfortable to you.

Install Dynamic Update Client

We're gonna be downloading the DUC from no-ip website.
$ cd /usr/local/src
$ sudo wget
$ sudo tar xzf noip-duc-linux.tar.gz

At this point you need to ls to check what version is the one you downloaded. At the time of writing the latest version is noip-2.1.9-1.

We need to build the sources now:
$ cd noip-2.1.9-1
$ sudo make
$ sudo make install

At this point you will be prompted by the installer for a few things:
Please enter the login/email string for
Please enter the password for user ''

This section only apply if you have multiple hosts for the same account.
2 hosts are registered to this account.
Do you wish to have them all updated?[N] (y/N)
Do you wish to have host [] updated?[N] (y/N)

Please enter an update interval:[30]
This is the interval which you want the service to update your IP address. I find 5 minutes to be frequent enough.

Do you wish to run something at successful update?[N] (y/N)
Unless you have specific needs, you don't need to run anything after the update so you can just say no to this one.

Run DUC as a service

We need to create a service to run the DUC in background.
Create the following file:
$ sudo vim /etc/systemd/system/noip2.service

Paste the following into the newly created file:

# Simple Dynamic DNS Updater
# By Nathan Giesbrecht (
# 1) Install binary as described in's source file (assuming results in /usr/local/bin)
# 2) Run sudo /usr/local/bin/noip2 -C to generate configuration file
# 3) Copy this file noip2.service to /etc/systemd/system/
# 4) Execute `sudo systemctl enable noip2`
# 5) Execute `sudo systemctl start noip2`
# systemd supports lots of fancy features, look here (and linked docs) for a full list:

[Unit] dynamic IP address updater


# Start main service

You can find Nathan's gist here.
(Thank you!!)

Save the file.

Enable the service (This will guarantee that it will restart after reboots.):
$ sudo systemctl enable noip2

Start the service:
$ sudo systemctl start noip2

Verify the DDNS gets updated

To verify that the DUC is updating the DDNS correctly you can go in the dashboard and verify that the "Last Update" field in Dynamic DNS -> Hostnames changed.

Additionally you can see the status of the service by typing:
$ sudo service noip2 status
This will output the last few lines of logs. You should be able to see something like this:

Jun 02 14:12:28 pi systemd[1]: Starting dynamic IP address updater...
Jun 02 14:12:28 pi noip2[833]: v2.1.9 daemon started with NAT enabled
Jun 02 14:12:28 pi systemd[1]: Started dynamic IP address updater.
Jun 02 14:12:28 pi noip2[833]: was already set to

Please note that the update only occurs if the IP changes. If you setup your IP when you created the new hostname it will not update until your IP differs.
Usually I set it to a different IP manually and restart the DUC to validate everything is working fine!

To restart the service type:
$ sudo service noip2 stop
$ sudo service noip2 start

Now, when we look at the status again, you can see that the IP has been updated.

Jun 02 14:29:11 pi systemd[1]: Starting dynamic IP address updater...
Jun 02 14:29:11 pi noip2[1173]: v2.1.9 daemon started with NAT enabled
Jun 02 14:29:11 pi systemd[1]: Started dynamic IP address updater.
Jun 02 14:29:11 pi noip2[1173]: set to


Hope I saved you some time and headache.
