It is a technology for dispersing servers that have the same IP address across multiple sites. By dispersing servers around the world, not only will the round-trip delay of packets be shorter, but you will have an advantage in terms of the failure resistance because the servers that could be attacked in a DDoS are diversified and localized.

In addition to Anycast sites provided by IIJ, hundreds of sites provided by business operators with a tie-up arrangement with IIJ’s DNS are available with the premium plan for this service.
