are however permitted to hold membership in such entities set up to hold a CGDN. As of November 2009, the auCD site claims 91 active CGDNs across Australia, with a further 115 either approved or awaiting approval. Third-level domains The use of ".gov.au" as a second level domain is for Australian Federal government and for its initiatives, while the use of a third-level domain, being an Australian state abbreviation, is an identifier that the domain belongs to either the relevant state government or a local government inside the state. The ".edu.au" is also split up into state-based categories in most cases. auDA has delegated responsibility of the .edu.au domain to Australian Information and Communications Technology in Education Committee (AICTEC), which formed a specialist sub-committee, .edu.au Domain Administration Committee (eDAC). Schools use a domain name that reflect their locale, and these state-based third-level domains are managed independently by the states. For example, a school in Western Australia would register "schoolname.wa.edu.au". Similarly, replacing the bold part of these domains, Victoria would use ".vic", Queensland would use ".qld", South Australia would use ".sa", Tasmania would use ".tas", Northern Territory would use ".nt" and the Australian Capital Territory would use ".act". However, after a change of internet services in Queensland State Schools their domain names were changed from "schoolname.qld.edu.au" to "schoolname.eq.edu.au" ("eq" is an abbreviation of the government department name "Education Queensland"). This is not the case for private schools in Queensland. Often, domains can even contain a fourth level: for instance, a NSW public school might have the domain "schoolname.schools.nsw.edu.au". Tertiary institutions are typically exempt from requiring state-based distinctions. For example, Edith Cowan University in Western Australia has a domain of "ecu.edu.au" rather than "ecu.wa.edu.au", Monash University in Victoria uses "monash.edu.au" rather than "monash.vic.edu.au". This difference can be associated with states having responsibility for primary and secondary education while the Commonwealth has responsibility for tertiary education; tertiary institutions often having a presence in multiple states. Historic second-level domains Some second-level domain names are no longer actively used. Whilst registrations are grandfathered for some, no new registrations are accepted. .archie.au – Host of the Archie information service of the early 1990s. Has since been deleted .conf.au – Conferences and other short-lived events, now only exists for linux.conf.au. .gw.au – Gateways and miscellaneous AARNet routing equipment. Has since been deleted .info.au – General information. Has since been deleted .otc.au – A mapping domain for X.400
