Domain Name Service (DNS) is an internet service that translates meaningful alphabetic names into numeric IP addresses which are given to computers, services or any resource participating in the Internet. DNS translates hostnames into IP addresses and IP addresses to hostnames. An example is WWW.VANDERBILT.EDU which translates to 18.104.22.168.
This is the current statement on use of Vanderbilt domain name services (which ITS operates for the University) to serve Vanderbilt and certain non-Vanderbilt domain names. Vanderbilt domain names are those registered and owned by Vanderbilt (at large) to represent Vanderbilt's presence in the Internet. Vanderbilt domain names consist of vanderbilt.edu, relevant VU-owned IP network reverse mapping domains, and domains such as vanderbilt.org which have been obtained to protect names associated with Vanderbilt in the Internet domain name space.
DNS Name Servers:
ITS retains official responsibility for maintenance of the top level DNS servers for Vanderbilt University. DNS servers are maintained by system administrators that adhere to University policies and practices related to server administration and security. The DNS servers are highly available (24 hours a day, 7 days a week).
Top Level Domains:
Vanderbilt.Edu is the top level domain.
DNS Requests must contain a sub-domain name as well as the Vanderbilt.edu top level name. (i.e. ITS.VANDERBILT.EDU) In this case, ITS is the sub-domain and VANDERBILT.EDU is the top level name. DNS requests may be requested at https://its.vanderbilt.edu/dns_iprequest.
In order to increase the efficiency of DNS requests, ITS may identify certain departments who are eligible for self-serve DNS. Departments will be identified for self-serve DNS based upon the amount of DNS resource records they possess, the frequency of changes to their resource records, and the pre-existence of DNS sub-domain(s). When identified, authorized users will be granted access to make and modify the DNS resource records applicable to their departments via web interface tools without having to submit requests to ITS. ITS shall provide training for the identified personnel to insure proper resource record maintenance.
DNS Sub-Domain Name Server Delegation:
Domain Name Service depends on designated servers having the proper authority to answer for the resource records within the assigned zones/sub-domains. This authority can reside at the top level zone/domain (i.e. Vanderbilt.edu) or selected zones/sub-domains can be delegated to another server performing DNS resolution (i.e. ds.vanderbilt.edu). Once a zone/sub-domain is delegated, that server becomes responsible for the authoritative name resolution of the resources records pertaining to that sub-domain.
It is the intent of ITS to maintain a centralized Domain Name Service authority to maximize security and appropriate Service Level Agreements.
DNS Naming Conventions:
ITS can provide Domain Name Service for University customers that are outside of Vanderbilt.edu instead of relying on the registrar.s DNS servers. Potential advantages of using the ITS DNS servers include ease and speed of resource record change and localized support through the existing ITS support structure. This service can be applied to both existing and newly created non-Vanderbilt Domains.
Domain name registrations must be explicitly requested by, and registered for the name(s) of appropriate Vanderbilt faculty or administrative staff in their role(s) as Vanderbilt departmental staff in order to maintain proper administrative and billing processes. These Vanderbilt affiliated people and departments are the sponsor(s) of the registering organization's requested use of Vanderbilt's domain name services. The registration should identify the technical contact as the ITS Network Operations Center, via the so-called "NIC handle" (or network identifier), NOC1576-ARIN, in the Network Solutions "WHOIS" database.
The responsible sponsoring person must provide a statement of sponsorship for the requested domain name in Vanderbilt's domain name servers and identify the sponsor's department and role at Vanderbilt. This statement should include assurance of intent to abide by the criteria outlined in this document. (It's suitable to do that by explicit reference to this text as an attachment, or as the ITS "stated criteria for serving a non-VU domain in VU DNS servers".) The statement should also include a short description of the purpose of the requested domain name and of the associated organization, group, or project. The statement should be provided to ITS via the request form at https://its.vanderbilt.edu/dns_iprequest.
If the host is off-site (non-Vanderbilt DNS servers), ITS will not support administration or changes for the off-site service nor will we provide reverse DNS entries or mail exchange configurations. If any of these criteria eventually fail to be met, then a previously justified domain name service registration will be reevaluated for disposal or transfer to another domain name service.
