Assign multiple ip addresses to single network card in linux
It’s apparent which i have assigned class A kind IP series i.e 192.168.1. to my network card. Let’s Say I want an different series, for instance 192.168.2.?
Just run the next command to create an additional IP.
$ sudo ip addr add 192.168.2.105/24 dev enp0s3
Here 24 signifies the netmask i.e 255.255.255..
Now, let’s see if the brand new IP continues to be assigned or otherwise.
$ ip addr
Sample output:
1: lo: mtu 65536 qdisc noqueue condition UNKNOWN group default qlen 1
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127…1/8 scope host lo
valid_lft forever preferred_lft forever
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
2: enp0s3: mtu 1500 qdisc pfifo_fast condition UP group default qlen 1000
link/ether 08:00:27:12:f8:c1 brd ff:ff:ff:ff:ff:ff
inet 192.168.1.105/24 brd 192.168.1.255 scope global enp0s3
valid_lft forever preferred_lft forever
inet 192.168.2.105/24 scope global enp0s3
valid_lft forever preferred_lft forever
inet6 fe80::a00:27ff:fe12:f8c1/64 scope link
valid_lft forever preferred_lft forever
As you can see within the above output, my network card has two IP i.e 192.168.1.105 and 192.168.2.105. Similarly you are able to assign as numerous additional IPs as you desire i.e 192.168.3.105, 192.168.4.105 etc.
Let’s ping the brand new Ip:
$ sudo ping -c 3 192.168.2.105
Sample output:
PING 192.168.2.105 (192.168.2.105) 56(84) bytes of information.
64 bytes from 192.168.2.105: icmp_seq=1 ttl=64 time=.040 ms

64 bytes from 192.168.2.105: icmp_seq=3 ttl=64 time=.066 ms

rtt min/avg/max/mdev = .040/.057/.067/.015 ms
Congratulations! It’s working!!
Wait, I haven’t finished yet. What we should did to date is we assigned the brand new IP temporarily. Once you reboot the machine, the brand new IP will disappear. How can you allow it to be permanently? It’s simple too.
Assign multiple IP addresses permanently:
Edit /etc/network/interfaces file:
$ sudo nano /etc/network/interfaces
Now, add some additional Ip as proven below:
iface enp0s3 inet static
address 192.168.2.105/24
Save and shut the file.
Run the next command to consider effect the saved changes.
$ sudo ifdown enp0s3 && sudo ifup enp0s3

Now, let’s run the next command to check on if the new Ip continues to be assigned or otherwise.
$ ip addr

- Imran Qureshi: Helpfull, but when i added ips range, ips are pinging but not showing on ifconfig / ip a command
- Tommy TBones Cramer: thank you, I was able to complete the first of several tasks on my Radio Server. I needed an extra ipaddress so I could run CentovaCast on port 80. I did have a bit of trouble understanding your english partly because you are very soft spoken. Tommy
