9.57 Domain Name Service Policy
Purpose:
To create a policy delineating how domain names shall be assigned at
the University. This policy is intended to:
a. provide consistency in naming the network domains for services and
organizations at the University of Northern Iowa, and
b. provide clarity and consistency to users of the UNI network.
Policy Statement:
Domain Name Service (DNS) is a mechanism used by the Internet community
to associate organizations with their electronic sites by assigning names
and associated IP addresses to specific computers on the Internet. DNS
is also used to provide the organizational affiliation and location of
service associated with a specific address.
The first two designations of a domain name are assigned on a national
basis. The University of Northern Iowa manages its presence on the Internet
under the domain name of "uni.edu". UNI is responsible for assigning
subordinate domain names (such as "calendar" in "calendar.uni.edu")
to specific Internet protocol (IP) address ranges. While there are no
published rules for domain name system implementation, agreement has evolved
within the Internet community on how names should be assigned. This agreement
assists users and network administrators in navigating an extremely (and
increasingly) complicated volume of Internet nodes.
Network Services (NS) in Information Technology Services (ITS) shall
be responsible for Domain Name Services (DNS) of the uni.edu domain (IP
address space 134.161.xxx.xxx) assigned to the University of Northern
Iowa. All uses of both uni.edu domain space and UNI IP address space shall
be in support of UNI and its mission. University faculty, staff, students
and component organizations desiring to use the university network must
register within the uni.edu domain. No domain names other than "uni.edu"
may be used by faculty, staff or university entities for university-related
business unless approved by the Vice President of the area and the Office
of Public Relations who will report all exceptions to the Cabinet.
Procedure:
1. Domain Name Format.
Domain names within uni.edu will follow a standard format and will automatically
be assigned when new machines are connected to UNI-NET. The format for
Standard DNS services entries is "L4.L3.uni.edu" where:
- The name structure follows the University’s organizational
structure.
- L3 (level 3) sub-domains will be University colleges, divisions,
schools, institutes, or departments that are officially recognized by
the university or campus-wide technology that serves the entire campus.
For example: "chaos.cns.uni.edu" for a college specific (CNS)
resource or "admin.uni.edu" for a campus-wide technology.
Assignment of Level3 sub-domains will be made by ITS with approval from
affected administrative units, and if exceptions are requested, in consultation
with the Office of Public Relations (OPR).
- L4 (level 4) sub-domains should reflect the specific service being
offered or follow a naming scheme within the department. For example:
cdrom.lib.uni.edu.
- L3 and L4 sub-domain names must not be trademarked, copyrighted,
distasteful, or misrepresent their function. Length limit for combined
names is 63 valid characters.
- Existing hosts or sub-domains registered under uni.edu that do not
conform to this policy will be reviewed to bring them into conformity.
2. Requesting a Domain Name Alias
A University vice president, dean, director, or department head may
request a domain name alias. DNS aliases provide a second, perhaps functional,
name for a specific computer. These names must be registered within the
uni.edu domain and adhere to standard layout for domain names (e.g. calendar.uni.edu
is an alias pointing to the computer that is actually named gecko.uni.edu).
In addition, a DNS alias may be used as a convenient mechanism for accessing
a specific WWW site. For example, the Mathematics department home page
physically located at spider.cns.uni.edu/math is also accessible using
the DNS alias of www.math.uni.edu.
University affiliates who have been approved to have a University web
site (see 9.58, World Wide Web policy) may be registered within the UNI
domain. University affiliates may also choose to register outside the
uni.edu domain (e.g. The Iowa Research and Education Network server, maple.iren.net,
is served from UNI-NET). DNS services will be provided to affiliate domain
names only if they are consonant with the mission of University.
Affiliate domain name aliases may be maintained by the University and
allowed to resolve to machines on the University’s network if both
of the following conditions are present:
- A significant number of people from different organizations inside
or outside the University will use the proposed name.
- The proposed name is not likely to be confused with the name of a
University of Northern Iowa department, function, service, or other
unit.
ITS will consult with OPR if there is a question over the proposed name.
