F-Root sites
ISC F-Root Sites
ISC sites are named after the nearest IATA airport code, followed by a number.
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.
