MCNC manages a distributed set of domain name servers for use in mapping hostnames to IP addresses. Name servers fall into two categories, authoritative and resolvers. Authoritative servers are used to host primary and secondary zone files for reference by the resolving name servers. Resolvers are used by systems to perform address lookups. MCNC currently deploys two authoritative servers and three resolvers for community use.
In addition, MCNC operates a Web GUI to allows our users to manage their own DNS if they desire. Access to recursive queries (lookup of addresses outside MCNC hosted zones) is restricted to systems with NCREN managed IP addresses.
There are no documents available at this time.
MCNC provides this service to the NCREN community without charge. Primary and secondary zone file hosting is available for NCREN customers and owners of location based zones managed by MCNC. If you would like to arrange for use of our DNS for your organization, or if you have questions about the service, please submit a web request.
Availability and Commitments:
Name servers are considered critical systems within MCNC. Multiple servers, on multiple network segments, are available for use, so that failure of a single server should not cause address lookup failures. DNS outages will be responded to within 15 minutes. New service or changes to existing service request will be responded to within one business day. While most changes to zone files are made during business hours, we will work to accommodate requests for changes at other times of the day and on weekends.
