ubuntu16.0.4 setting a fixed IP address and DNS

Because the company's computer every time the power-on reset assigned IP address is different, which leads to a lot of inconvenient things, so simply lock a fixed IP address, the following is the steps I lock the IP address:

1. Set the IP address

Vi/etc/network/interfaces

Add the following content:

# The Primary network interface

# ENP2S0 is your computer's network card, do not know what kind of network card, you can use the command ifconfig view
Auto Enp2s0
Iface Enp2s0 inet Static

# 192.168.2.83 is the IP address you want to fix
Address 192.168.2.83

# subnets and gateways can be viewed through route-n
Netmask 255.255.255.0
Gateway 192.168.2.1

2. Set up DNS

Vi/etc/resolvconf/resolv.conf.d/base
NameServer 114.114.114.114
NameServer 8.8.8.8

3. Refresh the configuration file

Resolvconf-u

4. Restart the Network Service

/etc/init.d/networking restart

5. Then restart the shutdown:

Using the Ifconfig command, you can see that the IP address is fixed.
