Floating IPs for added flexibility to develop your applications
Our OVHcloud dedicated servers, VPS or Public Cloud instances, include an IPv4 (/32) pre-configured and IPv6 IP block (/64).
For incredible flexibility, users can attach up to 256 additional IPs.
What is a floating IP? Floating IP is an additional IP that can be switched from one service to another in the same datacentre.
The key benefits of Floating IPs are
- Enable IP blocks so you can configure multiple IP addresses to your services
- Allow for failover so you can switch between services effortlessly
- Assign additional geolocated IPs to expand your global audiences
Adding IP blocks allows you to configure multiple IP addresses to your services. It’s possible to assign IPs into groups of 4, 8, 16, or up to 256 per server, with unlimited block publications. Via the API, blocks can be separated to allow for easy management of your applications. This makes upgrades simple, as you can reroute your IP to new hardware rather than having to reconfigure the static IP. With multiple IPs, grouped into Blocks, you can manage your platforms more efficiently – upgrading and migrating from one service to another with ease. IP blocks increase your control and speed for quick execution of business strategies and response.
Failover IPs, also named Floating IPs, can be switched from one service to another in a few seconds. This provides you with an uninterrupted hosting solution and helps you overcome the headache of hardware failure, system overruns and all kinds of infrastructure problems. This way, if you switch from one service to another, you can keep the entire configuration linked to that IP. Floating IPs provide a solution which removes interruption or downtime if servers are overrun and can be utilised in this way for “Always On” availability.
Floating IPs to meet your needs
Developing complex infrastructures that are resilient to issues is no easy feat. It requires hardware to be networked in a way that can respond to breakdowns, services overload, and maintenance issues.
With Floating IPs, also known as failover IPs, it is possible to create complex infrastructures that can withstand a wide variety of problems. For example, it is possible to switch your existing infrastructure to a load balancer without disrupting or interrupting your customer services. Workloads can be balanced autonomously, while your online space continues as normal. There will be no noticeable IP address changes as you will always use Floating IP, which means no DNS propagation delay.
For most online projects, hosting more than one site is a business essential. For any kind of dynamic web page – such as blog, online store, or membership portal – it is likely that you will need an admin page as well as a public-facing site to deal with ongoing changes. Or if you support multiple languages, you will need multiple webpages. Floating IPs allow you to keep your websites on the server but without the risk of excessive downtime or website crashes due to overloads.
You can host multiple websites on a primary server by using two Floating IPs. Some of your websites can be hosted on one Floating IP and the rest on another. When one server isn’t powerful enough to host the website for both the Floating IPs, you can get a new server, then switch the routing of one Floating IP to the new server. This relieves the primary server of the heavy workload, so it can be operational again.
Growing your storage, expanding clusters and other changes that promote business growth come with a risk of downtime, which can cost your business dearly in sales and reputation. With Floating IPs, it is possible to curb the risk of downtime altogether. By following the steps to integrate a Failover IP system for your projects, it is possible to grow infrastructure while at the same time executing uninterrupted performance on each of your sites
Importantly, floating IPs are highly customizable and therefore can be utilised to solve business goals. For example, with IP Announcement services it is possible to announce multiple geo-locations for your IP addresses. This is incredibly important for SEO optimization, as it considerably improves the referencing of your projects in the main search engines.
What is failover IP / ARIN IP ?
What is failover IP ?
A failover IP, also called a Floating IP, enhances the continuity of services (“failover”) for your applications and systems. The failover IP technology allows you to switch the IP addresses from one service to another in less than a minute, with almost no interruption to services for your users. This mechanism can be used during service migrations; moving projects from development to production environment and switching services to the backup server in case of failure.
How to get an IP address?
To take advantage of both a failover IP setup and ARIN IP you will need to know how to get an IP address. With OVHcloud, getting an IP address is simple: login to the control panel and take the appropriate steps. With a dedicated server, IPs can be configured in alias or bridge mode for virtualisation purposes.
What is a ARIN IP address?
ARIN IP address is a IP address managed and distributed by the American Registry for Internet Numbers. One of the main activities of ARIN is to allocate the IP blocks to ISPs (Internet Service Providers) and register the data in a public database. ARIN IP addresses can be assigned to IP blocks or used as failover IPs.
