Set a static IP and netmask:

$ ip addr add 192.168.1.100/32 dev eth0

Remove a IP from an interface:

$ ip addr del 192.168.1.100/32 dev eth0

Remove all IPs from an interface:
```
$ ip address flush dev eth0
```
Display all routes:
```
$ ip route
```
Display all routes for IPv6:
```
$ ip -6 route
```
Add default route via gateway IP:
```
$ ip route add default via 192.168.1.1
```
Add route via interface:
```
$ ip route add 192.168.0.0/24 dev eth0
```
Get the route used for an destination
```
$ ip route get to 8.8.8.8
```

Change your mac address :

$ ip link set dev eth0 address aa:bb:cc:dd:ee:ff

Let's say you have a network, e.g. 192.168.1.0/24, so with the following IP range: 192.168.1.42 to 192.168.1.254.

Now you want to connect to this network with the following address: 192.168.1.42.

Here is how to do it with ip:

Stop the DHCP service:
```
$ sudo systemctl stop dhcpcd.service
```
Check your interfaces:
```
$ ip a
```
Choose an available interface, e.g. enp1s1.
Add an IP address (192.168.1.42) to your interface:
```
$ ip addr add "192.168.1.42/24" dev enp1s1
```
Add a gateway (e.g. 192.168.1.254), if your network has one:
```
$ ip route add default via "192.168.1.254" dev enp1s1
```

Add a DNS (e.g. 192.168.1.1), if your network has one:

$ echo "nameserver 192.168.1.1" >> /etc/resolv.conf
