new static ip address on ubuntu server

If I have trouble in achieving this I allow my server to obtain an IP address from the router. I then log into the router and reserve this IP on the router for the mac address of my server. Works and never fails.

It is normally your router that will be assigned your public external IP address, not your actual server.

Your server will then be assigned an internal / private IP address, probably something like 192.168.x.x something along those lines.

So long as you have the necessary ports forwarded correctly from your router to your server you should be able to access your server via your new static IP address that has been provided by your new Internet Provider.

The only situation that this MAY be different is if you have your server set up in the DMZ of your router as SOME routers will then directly assign your public / external IP address to whatever single device you have in the DMZ. But it is unlikely / unadvised that you operate in this way

Here try this

####MAKE STATIC IP ADDRESS####

sudo nano /etc/network/interfaces

and make it look like this choosing your own ip address extension

example i am using 150

change the dhcp to static and add these lines so it looks like this Using your configs as 0.1 is for wired and 1.1 is wireless i am using wired in this example

auto eth0:0

iface enp3s0 inet static

address 192.168.0.150

netmask 255.255.255.0

broadcast 192.168.0.255

network 192.168.0.0

gateway 192.168.0.1

dns-nameservers 8.8.8.8

dns-nameservers 8.8.4.4


Now to CTRL-X and then Y to save

and to restart network with new ip type the following and press ENTER

service networking restart or just reboot

sudo reboot (hit enter)

Hope this helps :-)
