Find out what you interface is labeled using either the ifconfig or "ip a" command.
Example using ifconfig:
enp3s0f0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 1.1.1.1 netmask 255.255.255.0 broadcast 1.1.1.255
ether 5c:b9:01:79:7e:18 txqueuelen 1000 (Ethernet)
RX packets 272893777 bytes 85125059397 (79.2 GiB)
RX errors 411 dropped 20 overruns 0 frame 0
TX packets 163007862 bytes 85194460331 (79.3 GiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
Example using "ip a":
root@194:~# ip a | more
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
valid_lft forever preferred_lft forever
2: eno1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000
link/ether 34:17:eb:e7:d4:ee brd ff:ff:ff:ff:ff:ff
3: enp3s0f0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
link/ether 5c:b9:01:79:7e:18 brd ff:ff:ff:ff:ff:ff
inet 1.1.1.1/24 brd 194.34.107.255 scope global enp3s0f0
valid_lft forever preferred_lft forever
You can see the interface is labeled "enp3s0f0".
So to bind an ip to this interface, you simply need to do:
ip a a 2.2.2.2/32 dev enp3s0f0
To make the ip binding persistent across reboots, make sure to add that to /etc/rc.local so it would look like this:
#!/bin/bash
ip a a 2.2.2.2/32 dev enp3s0f0
