Introduction to Domain Name Service (DNS)
Domain Name Service, often referred to as DNS, performs a mapping
between names and ip addresses for machines using the TCP/IP protocol.
All TCP/IP machines have an individual address, or ip number, such
as 150.203.2.15, or 203.10.76.34. This address is used when your computer
contacts another computer which is also using TCP/IP. Because these
numbers are difficult for humans to remember each machine also has
an individual name, such as 'leonard.anu.edu.au' or 'supreme.pcug.org.au'.
Domain Name Service is the method used to match up names to the correct
ip number.
Computers on the ANU campus will normally be configured by the local
IT support to automatically use DNS.
The Australian National University uses the domain name "anu.edu.au" Hosts
in the ANU campus have an IP address in one of the following blocks:
Network Location
150.203.xxx.yyy
Most Hosts on the ANU campus and observatories
130.56.xxx.yyy
Chancelry and ns4.anu.edu.au
203.0.19.yyy
Addresses at the Northern Australian Research Unit
DNS Name Requirements
The following principles for Internet domain naming and for the allocation
of addresses within the University’s public IP address space
apply:
- The University has licensed the 3rd Level Domain (3LD) anu.edu.au
which is registered with auDA under the Closed .edu.au 2nd Level
Domain (2LD).
- The University has been allocated public IP address ranges by APNIC
and adheres to APNIC policies and guidelines.
- The University allocates IP addresses to the University Community
and to non-ANU Entities in conformance with APNIC principles of uniqueness,
area aggregation, conservation and fairness.
- All servers supporting one or more services that are provided by
members of the University Community as part of their official functions
and as part of the business of the University must have domain names
registered within the anu.edu.au domain for each service offered.
- Domain names within the anu.edu.au domain are to be registered
with the University’s DNS name server either as a 5th Level
Domain name (5LD) or, in some cases, a 4th Level Domain name (4LD)
depending on the scope of services being offered.
- Budget Unit network connecting devices have domain names allocated
at the 5LD in the general form “[hostname].[budget unit identifier].anu.edu.au”,
where [budget unit identifier] can be College, Research School, Centre
or Administration Division identifiers and, where applicable, use generally
accepted Internet community conventions, such as “www.[ budget
unit identifier].anu.edu.au” or “ftp.[ budget unit identifier].anu.edu.au”.
- Wherever possible, the auDA principle of “first come, first
serve” allocation of domain names will be applied by the University’s
Hostmaster within the anu.edu.au domain and other approved domain
names.
- Approved domain names must conform to auDA’s naming rules
for unacceptable names and must not contravene trademarks or copyrights.
- The University reserves the right to rescind and reuse domain names
for new and more appropriate University purposes.
- 4LD domain names which are of the form “[hostname].anu.edu.au” are
approved by the University subject to the following criteria:
- services are general to the University or common to the
University Community, eg “www.anu.edu.au”.
- The proposed name is for a consortium of many different groups within
the University.
- The proposed name is the name of a service and not the name of a
Budget Unit.
- Existing 4LD’s which do not meet these criteria are
grandfathered for the life of the particular service only.
- The University allows the use of domain names outside the anu.edu.au
domain, subject to the following criteria:
- The domain name must be registered with a domain registrar within
the open 2LD at the 3rd Level which satisfies the auDA 2LD criteria
([hostname].com.au, [hostname].net.au or [hostname].org.au).
- Any hosts supporting services that are provided by members
of the University Community, but that are outside their official
functions or outside the business of the University must use
domain names outside the anu.edu.au domain, however, within
the University’s allocated IP address ranges.
- The proposed name is not likely to be confused with the name of a University Budget Unit.
- The proposed name
- signifies an organization or venture, commercial or
non-commercial, that is not explicitly part of the University;
or
- is for a project with external funding which is obligated to show this identification for Internet access; or
- is used by many people from many different organizations outside the University.
- The University approves the use of the ANU’s ABN
for the registration.
- Individual members of the University community are not allocated
University IP addresses for the purposes of registering domain names
in the .id.au open domain (or in attempting to register in any other
open 2LD).
- Further registration in overseas domains, in particular, the .com
domain are allowed where the naming is for commercially strategic use
or for international recognition.
- All domain names requiring registration by auDA are to satisfy both
auDA naming rules and the Use of the University Name and Insignia Policy.
- All host names and aliases are to conform to the auDA’s
naming rules for unacceptable names and are not to contravene
trademarks or copyrights.
- CNAME records for virtual domain naming of virtual hosts
or the customised naming of URL’s on University or Budget Unit main servers must
have alias names aligned to the naming hierarchy of the main server’s
domain name.
- In some instances, the University may determine a need to register
domains, including those in the .com top-level domain, 2LD, to protect
the ANU brand to prevent cybersquatting.
- The University allows the sub-delegation of DNS services to Budget
Units where workstation management at the 5LD requires local name servicing.
- Non-ANU Entities which are allocated University IP Addresses must
register separate domain names outside the anu.edu.au domain.
The complete policy on Internet Domain Naming and IP Addressing
Please Note: The Director DoI reserves the right to deregister or
refuse to register any name that is considered inappropriate or unsuitable.
Registering an ANU IP Address
Before registering a domain name please read DNS Name RequirementsIn
general, IP addresses are issued to local IT support people (LITSS).
The normal procedure is to send e-mail to hostmaster@anu.edu.au stating: The subnet on which the address is required (eg 150.203.23).
The unique name(s) required. Please use lowercase characters when
submitting request. NOTE: The _ character is NOT permitted in the
DNS.
Business area (ie SDS, RSES, CECS, etc.)
The equipment type (ie PC, Mac, Sun, etc.)
The operating system (ie VISTA, XP, MACOS, OSX, SUNOS, SOLARIS, LINUX
etc.)
Any aliases (cnames) required for the machine
Any mail exchange information required for the machine (only for
Unix hosts, name of machine which handles mail).
Alternatively, this information can be submitted by logging a Request
via the DoI
Helpdesk (Link will open in new window/tab) system;
1. Click the "Register a Request" tab.
2. Click the drop arrow in "Topic" and select "Network".
3. Click the drop arrow in the selection box directly under "Topic" and
select "IP Address Change".
Please ensure that you enter ALL details.
The required entry field entitled "Category should be set to "All
other Support".
