Should You Use Another IP Address? Here's How to Add One to Your Linux Server

Your Linux server naturally comes with its own public IP address, but there's a way to add another one to your server if you want. In this article, you will learn the importance of getting a new IP address and how to do it the right way.

Importance of Acquiring a New IP Address

Getting another IP address has many advantages. If you have many IP addresses, you can operate multiple apps in just a single port. Running apps can sometimes be conflicting, especially if they are tied to one IP address. This way, you can avoid this hassle and access them with ease.

If you're having problems with web content servers, you might want to address this through a reverse proxy. This particular server places the content in other locations under one port.

Additionally, Docker goes well with multiple addresses. For those who don't know, Docker is a software platform used in handling apps into portable containers.

What's more is that when you have many external IP addresses, there's nothing to worry about if the apps won't run or not in a machine.

How to Add an Extra IP Address to Linux Server

All over the world, the public IPs have been scattered. However, the internet firms might have already taken hold of some of them. Still, there's a way for you to acquire an additional IP to your Linux server.

You can actually rent them or buy them right away from reputable cloud providers if you have a budget intended for them.

While other companies will only allow you to purchase one IP address, other providers could hand you a nice package of more than two addresses.

As for corporations, they could amass a myriad of blocks through a brokerage. However, it is expected to be much more expensive than the other offers since the IP addresses can cost over $1,000.

There's a need to configure the network interface so the server would positively respond when a new IP address has been placed.

How to Configure Linux to Access Many IP Addresses

Configuring the Linux server can be tricky but some steps can help you deal with that. For instance, Ubuntu's netplan relies on YAML templates, and here's how you can use it.

First, make a template located in /etc/netplan/config.yaml. Then, you can now start the configuration. Below is a sample configuration that you can change later.

network:

version: 2

ethernets:

eno1:

addresses:

- 123.1.2.3/32

After that, make sure to specify the IP addresses as singular /32 blocks. Once you're done, test the netplan through sudo netplan try.

If it is operating on your end, launch the configuration via sudo netplan apply, then run tcpdump to begin the debugging process for the routing.
