Solution 1

I suggest you amend the file /etc/network/interfaces to read:

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto enp2s0
    iface enp2s0 inet static
    address 192.168.0.10
    netmask 255.255.255.0  
    gateway 192.168.0.181
    dns-nameservers 8.8.8.8

Get the system to re-read and use the changes:

sudo ifdown enp2s0 && sudo ifup -v enp2s0

The -v for verbose should produce some output that tells us if the address was given successfully. Test:

ping -c3 192.168.0.181
ping -c3 8.8.8.8
ping -c3 www.ubuntu.com

If you get ping returns, you are all set.

Solution 2

You can use the following

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto enp2s0
    iface enp2s0 inet static
    address 192.168.0.10
    netmask 255.255.255.0  #depends on your network class of address
    gateway 192.168.0.1    #address of the server that allow you to connect internet or other networks.
    dns-nameservers 8.8.8.8     #domain names resolver 8.8.8.8 it's google's public dns

then

$ sudo touch /etc/network/interfaces.d/enp2s0

then

$ sudo ifdown enp2s0 && sudo ifup enp2s0

I am totally new to ubuntu server(did not work with any server before). I have installed LAMP(apache2, mysql, php) on ubuntu server(16.04.1 LTS). It works all correctly. It has 192.168.0.22 Ip.

On other computers, there are windows 7 installed(192.168.0.45).

When i write ubuntu server's ip in windows browser, it works but when i write localhost on windows browser it does not work but it does work on ubuntu server.

So now I want to set custom/static ip on ubuntu server this 192.168.0.11 its totally does not work neither in ubuntu server browser or neither ping neither ping www.google.com

my /etc/network/interfaces is something like this
```
source /etc/network/interfaces.d/*

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto enp2s0
iface enp2s0 inet dhcp
```
I dont have eth0. I did everything to find it but did not find

How i tried to change ubuntu server ip to static
```
# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto enp2s0
iface enp2s0 inet static
   address 192.168.0.11
   netmask 255.255.255.0  #<-- random i dont know what should i have to write here
   gateway 192.168.0.1    #<-- random i dont know what should i have to write here
   network 192.168.0.10   #<-- random i dont know what should i have to write here
   broadcast 192.168.0.12 #<-- random i dont know what should i have to write here
   nameserver 8.8.8.8     #<-- random i dont know what should i have to write here
```
my /etc/hosts
```
127.0.0.1  localhost
127.0.1.1  web

#The following lines are desirable for IPv6 capable host
::1       localhost ip6-localhost ip6-loopback
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
```
Repeat I dont have etho

Command :
```
root@web: # ipconfig -a

enp0s25   Link encap:Ethernet hwaddr .......
          broadcast MULTICAST MTU:15000.....
           ... 0... 0...0 ..
           .................................
           .................................

  @Arronical yes i did

  As Arronical notes, your network and broadcast lines are incorrect. network would be 192.168.0.0 and broadcast 192.168.0.255, but you can just omit them instead.

  so should i do like this auto enp2s0 iface enp2s0 inet static address 192.168.0.10 netmask 255.255.255.0 gateway 192.168.0.1 network 192.168.0.0 broadcast 192.168.0.255 nameserver 8.8.8.8 and getway ? should i add ?

  @user4556274 should i configure/etc/hosts ?
- user4556274 almost 8 years
  
  /etc/hosts is used for local name resolution. It is not relevant to the specific question of setting a static IPv4 address.

  ok last thing, i want to be clear should i do like this auto enp2s0 iface enp2s0 inet static address 192.168.0.10 netmask 255.255.255.0 gateway 192.168.0.1 network 192.168.0.0 broadcast 192.168.0.255 nameserver 8.8.8.8

its work but i am not able to connect to the network (ping google.com)
Phoenix almost 8 years

it is not connected to internet now.. what i do ?
user4556274 almost 8 years

Make sure that the gateway line gives your actual gateway IPv4 address. If you don't know your gateway address, but your windows machines have internet connectivity, run ipconfig on one of the windows machines to see what the gateway address is.

gateway predefined 192.168.0.181

I tried everything but does not work :(
chili555 almost 8 years

What do other devices, Windows computers, iPads, iPods, etc., on the same network show as the gateway?
Phoenix almost 8 years

my windows pc shows me 192.168.0.181 and i check on server using netstat -rn it is showing me same 192.168.0.181
Phoenix almost 8 years

server let me use custom ip but it is not acessing the internet... i use command ping www.google.com but does not do anything
chili555 almost 8 years

192.168.0.181 is the gateway address on the Windows PC, Is the correct? The gateway?
Phoenix almost 8 years

It's not needed. Is it working as expected now?

I don't understand. Are you saying that you included -v verbose and an actual part of the command? That's not what I suggested.
Phoenix almost 8 years

oops sorry i convinced that is in code... sorry btw i have solved problem using different address, i do not what problem had with 192.168.0.11. i changed to 192.168.0.50.
Phoenix almost 8 years

ok. i did. ty for helping. i have one more question My server is running on 192.168.0.50 on LAN from my workstation. But now i want to access it from my house
