DNS Services

• Primary Nameserver Service provides a basic DNS service for JANET customers based on high availability primary and secondary nameservers that satisfy DNS queries for the zone data they hold. The servers are situated on the JANET backbone and geographically separated as a precaution against fire or the failure of network connection. The service is ideal for some small organisations which do not have the resources themselves to operate nameservers and maintain DNS information.

• Secondary Nameserver Service is available to any customer with a primary connection to JANET. Under this service JANET(UK) will arrange for a secondary nameserver to be run on the customer's behalf at a remote site on the JANET network. There is currently no charge for this service.

• Off-site Resolver Service provides a DNS resolver service for organisations with very small networks for whom it is inappropriate to use an on-site resolver. Dedicated resolvers located on the core of the JANET network answer queries for domain name resolution that come from client computers on a customer organisation's network. Having sent a DNS query to the appropriate nameserver to find the required IP address, the information is returned to the client enabling the computer to access the remote host machine.
  


• Domain Name Registration provides a service for the registration of .ac.uk and .gov.uk domains.
