F-Root Sites

If you think your users would benefit from the improved DNS stability that a local F Root Server would bring, but there is no F-Root Server listed for your city or region, let us know. We are in the process of adding more sites.

If you are a researcher and your research involves F.root-servers.net in any way, please contact us at f-root@isc.org and we will be happy to provide you with information on many aspects of F-root, first hand.

Which F-root node am I using?

To ensure that your users have access to an appropriate local root server it can be useful to find out which instance of the F-Root Nameserver you are currently using. If there is a site listed close to you but you do not appear to be using it, ask your ISP to contact us so we can make the local site available to their customers.

To find out which F-Root site is answering your queries, try one or both of the following:

    • traceroute F.ROOT-SERVERS.NET

The route your packets take to reach F should give you some information about which site you are using. The site code used to name the ISC routers at the end of the trace can be looked up in this page.

    • dig +norec @F.ROOT-SERVERS.NET HOSTNAME.BIND CHAOS TXT

This command sends a query to the F root nameserver, asking it to reveal the name of the particular server which answers the query. The hostname will contain a site code, allowing the location of the server to be identified. The dig utility is distributed with ISC BIND 9.
