Floating IP Address
Posted on July 25th, 2023
In today’s fast-paced and dynamic cloud computing landscape, the ability to adapt quickly to changing infrastructure demands is crucial. Floating IPs have emerged as a valuable solution, offering a single static IP address that can be moved seamlessly to any destination within the same region. In this blog post, we will delve into the concept of floating IPs, explore their practical applications, and demonstrate how to manage them efficiently through our platform.
What is a Floating IP?
A floating IP is a fixed public IP address that can be re-assigned and moved between different servers or instances within the same geographical region. This allows you to decouple your IP address from any specific physical server, providing unparalleled flexibility and versatility for your infrastructure.
Seamless Failover and High Availability
One of the primary use cases of floating IPs is achieving high availability and redundancy for your applications. In the event of a server failure, you can quickly reassign the floating IP to a standby server, minimizing downtime and ensuring uninterrupted service for your users.
Floating IPs are an essential component of load balancing setups. By distributing incoming traffic across multiple servers, you can optimize resource utilization and improve overall system performance.
When you need to migrate your applications or data from one server to another, a floating IP streamlines the process. Instead of updating DNS records or waiting for propagation, you can effortlessly redirect users to the new server.
Managing Floating IPs
At InterServer, we provide a user-friendly control panel to manage your floating IPs effectively. By following these simple steps, you can make the most of this feature:
Accessing the Control Panel
To begin, log in to your InterServer account and navigate to our control panel at https://my.interserver.net/view_floating_ips_list.
Ordering a New Floating IP
If you require an additional floating IP, click on “ORDER” at the top of the control panel. You’ll be prompted to input a valid destination IP address, which must be currently assigned to one of your servers.
Configuring the Floating IP
After obtaining your floating IP, you need to configure it on your server’s interface. Utilize the following example command to add the floating IP (in this case, 22.214.171.124) to the network interface ‘enp0s3’:
ip addr add 126.96.36.199/32 dev enp0s3
Using the API
For users who prefer automation, InterServer offers an API to manage floating IPs programmatically. The API documentation can be accessed on our website, providing you with full control over your floating IPs.
Floating IPs represent a powerful tool for modern cloud infrastructure management, granting you the flexibility to adapt to changing requirements with ease. Whether it’s ensuring high availability, load balancing, or simplifying server migrations, floating IPs offer a seamless and efficient solution. By managing your floating IPs through our user-friendly control panel or API, InterServer empowers you to harness the true potential of this remarkable technology, taking your infrastructure to new heights.
