OARnet provides a fully managed authoritative and recursive Domain Name Service (DNS) utilizing geo-redundant carrier-grade DNS servers. Our engineering team can assist clients with domain name registration, design, implementation, and troubleshooting.

Customers can utilize the OARnet DNS service as any combination of fully managed primary and secondary, redundant load-sharing secondary, blind primary, recursive, or as forwarders for campus resolvers.

Utilizing OARnet DNS service in combination with our Distributed Denial of Service (DDoS) mitigation service can eliminate the risk of common DNS-based volumetric DDoS events impacting your organization.

Most DNS requests can be completed in one to two business days, depending on complexity.

Need to Modify an Existing Domain?

DNS requests must be submitted by an Administrative, Technical or DNS contact from the OARnet Gateway, and they must be sent in writing. The written request avoids errors that can occur when trying to collect host names or IP addresses over the telephone. Once the Service Desk receives a request, we open a ticket on this issue and assign it for processing. Individual organizations are responsible for updating domain registration records with their registrar.

Please see the OARnet DNS Policy for further information.

Higher Education Clients

EDUCAUSE is the sole registrar for names in the .EDU domain. Requests for new names in the .EDU domain are accepted on a first-come, first-served basis from eligible institutions that do not have any other previously registered .EDU domain names. At this time, there are no registration fees associated with valid registrations in the .EDU top-level domain.

Eligibility for registering a domain in the .EDU top-level domain is limited to degree-granting institutions of higher education, including two-year community colleges and four-year colleges and universities. .EDU domains registered before October 29, 2001 are grandfathered into .EDU, regardless of compliance.
