IPV4 Setting up in Linux OS–Easier Than Imagined

When it comes to networking, IPV4 (Internet Protocol Version 4) helps connect one or more computer devices to the Internet. Setting up IPV4 in Linux OS can be a tough task, but with the right steps in place, it is easier than imagined.

When setting up IPV4, it involves configuring the network interface using a static IP address or DHCP (Dynamic Host Configuration Protocol).

If you choose to use a static IP address, you will need to create a file in etc/sysconfig/netork-scripts, which would be named ifcfg-etho or ifcfg-eno1 depending on which Linux version you have.

In this file, you will configure the network interface to monitor your IP address. This includes entering the following information:

DEVICE=eth0

BOOTPROTO=none

ONBOOT=yes

IPADDR=…

NETMASK=255.255.255.0

GATEWAY=yyy.yyy.yyy.yyy

DNS1=zzz.zzz.zzz.zzz

Once you have entered all the necessary information, you can then save the file and restart the network interface by running the command ‘ service network restart’.

If you choose to use DHCP, you will need to configure the DHCP server, using the following commands:

#ifconfig eth0 up

#dhclient eth0

Once the server is running, the IPV4 configuration is complete and the device should now have internet access.

Regardless of which method you choose, setting up IPV4 in Linux OS is quite easy and can save you time and energy when it comes to networking. It is important to note that if you choose to use a static IP address, you need to make sure that the address is not assigned to any other device, otherwise it could cause conflicts when connecting to the network.

Overall, setting up IPV4 in Linux OS is an easy task with the right steps in place. You can either configure the network interface using a static IP address or setup DHCP, depending on the needs of your device. As long as you are aware of the rules and regulations when it comes to IPV4 addressing, setting it up in Linux OS should cause any issues while establishing an internet connection.
