No ip ubuntu not updating
It used to be called “eth0” or “eth1”, but as from Ubuntu 15.10 the interface name is now allocated based on a few other factors – read more about that here if you’re interested.
Simply comment, remove or edit the line that says ends with “dhcp” and add the following information (here’s an example only): Next you’ll want to add the nameservers by adding the line “dns-nameservers” followed by a list of IP addresses.

In this case, look for the line in the file that says “# The primary network interface” and directly beneath this you’ll see something like (the default DHCP configuration): If you’ve been using previous versions of Ubuntu you might have noticed that the interface name above “ens160” looks a bit odd.
I'm running Ubuntu server so I'm using apt and nano, but this should work on anything POSIX based such as Mac OS X, BSD, any flavor of Linux -- even the Raspberry Pi.
The script can be run as a single instance with command line parameters, as a daemon, using crontabs (a utility for running programs on a schedule) or as a Linux service. This is usually installed by default on most Linux and BSD distros, but if not use your package manager to install it.
There was no output to the console or to a log file either to diagnose the problem that I could find, so I decided to go about writing my own, which really wasn't that hard to do using a bash script and a few simple utilities on my Linux box.
Editing the /etc/network/interfaces file in Ubuntu 16.04 to add a static IP address " data-medium-file="https://mjmckinnon.files.wordpress.com/2016/05/edit-interfaces-file.png?
NO-IP then associates that IP with the domain name so services can be setup against the domain rather than the IP that changes. Many routers have a built in NO-IP client, but my router doesn't support NO-IP, and for whatever reason, I could never get the client that NO-IP recommended for a Linux host to work.
I downloaded the source and compile it following the instructions, and it appeared to be running, but it never updated my IP address.
Runs the script as a daemon with the settings in the config file in the default locaion /etc/no-ip/
The config file uses a simple syntax to define parameters.
