Floating IPs: Failover IPs, Geo IPs & IP blocks

OVHcloud Floating IPs

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. You can also switch IPs between different datacentres, if the datacentres are located in the same country.

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

IP blocks

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 Capabilites

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.

IP Geolocation

With our announcement IP service, you are able to expand your project for a global audience. OVHcloud allows you to link to additional geolocated IPs. Additional IPs can be geolocated in 14 available destinations. This considerably improves the referencing of your projects in the main search engines, infinitely improving your webpages SEO status.   

Floating IPs to meet your needs

complex OVHcloud infrastructures
Create complex infrastructures without single points of failure

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.

Host multiple websites OVHcloud
Host multiple websites on the same instance

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 OVHcloud storage
Grow your business

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 customisable and therefore can be utilised to solve business goals. For example, with IP Announcement services it is possible to announce multiple geolocations for your IP addresses. This is incredibly important for SEO optimisation, as it considerably improves the referencing of your projects in the main search engines.

What is failover IP / RIPE 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 RIPE 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 RIPE IP address?

RIPE IP address is a European IP address managed and distributed by European IP Networks (in French Réseaux IP Européens). It is an open community that ensures administrative and technical conditions to maintain and develop the Internet. One of the main activities of RIPE is to allocate the IP blocks to ISPs (Internet Service Providers) and register the data in a public database, including information, such as country’s IP blocks ranges, current IP allocation and IP geolocation.

At OVHcloud you can choose the geolocation of your RIPE IP block, and choose between 13 European countries: France, Ireland, Portugal, the United Kingdom, Italy, Spain, Poland, Czech Republic, the Netherlands, Finland, Lithuania, Germany and Belgium. With RIPE IP blocks it is possible to tailor your addressing plan to your needs, choosing blocks from 4 to 256 IPs and managing their reverse DNS (PTR) in your control panel.

For IPs geolocated in Canada or the United States, ARIN – the American Registry for Internet Numbers – oversees the management and distribution of IP addresses. ARIN IP addresses can be utilised in the same way as other RIPE IPs and can be assigned to IP blocks or used as failover IPs.
