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.

In 2014 we added new nodes in Kuala Lumpur and Chennai, India, and updated several others to IPv6. We also developed a new, smaller (less expensive) F-root node design, suitable for sites with less traffic. We welcome inquiries from sites interested in hosting and sponsoring a new F Root node.  Read our Network Operations Report for 2014.

As of February 18th, 2015, we have just added our newest F-root node, in Luanda, Angola.
