F Root

ISC has operated F-Root, one of the world’s thirteen root name servers, since 1994. We also provide secondary DNS hosting for 50 ccTLDs around the world.

F-Root is distributed using “anycast” technology with 57 operational locations carrying ~25% of all root name server traffic, and operating an average 16,000 queries per second.

We welcome inquiries from sites interested in hosting and/or sponsoring a new F Root node.  Read our Network Operations Report for 2014.

We added our newest F-root node, in Luanda, Angola, in February, 2015. We promoted our Amsterdam node to be our first Global node outside the US in early March. F-root nodes in Santiago, Chile and Rome, Italy have fresh new hardware.


These organizations are among those supporting ISC’s Open Source mission through their ISC open source support subscriptions.
