ARIN IP Failover block

Additional personalized IPs for your server


With an ARIN IP Failover block, you can assign a block of 4 to 256 additional IP addresses to the dedicated servers and virtual machines of your choice.

The ARIN IP Failover block is an ideal solution to enhance the continuity of services for your applications ("fail over"). It allows you to optimize your SEO and geolocate your IPs to Canada or the USA.
