[[File:AARNet timeline.svg|thumb|350px|right|Key milestones in the creation of the Internet in Australia]]

AARNet1 (1989–1997): Australia's first Internet:<ref name=Xamax />
* AARNet-operated [[layer 3]] [[Router (computing)|routers]]; one [[point of presence]] (PoP) per capital city
* national backbone: carrier-provided ([[Telstra]]) inter-PoP transmission capacity
* carrier-provided trans-Pacific transmission capacity
* AARNet1 sold to [[Telstra]] in 1995

AARNet2 (1997–2006): Fostered the building of [[Optus]]' [[Asynchronous Transfer Mode|ATM]] and Optus' Internet networks:<ref name=AARNet20YearBook />
* AARNet-operated layer 3 routers; one PoP per capital city
* national backbone: carrier-provided ([[Optus]]) inter-PoP [[Asynchronous Transfer Mode|ATM]] transmission capacity
* carrier-provided trans-Pacific transmission capacity

AARNet3 (2006–2013): The AARNet optical network:<ref>{{cite web|title=AARNet Annual Report 2004 |url=http://www.aarnet.edu.au/library/aarnet_annual_report_2004.pdf |archive-url=https://web.archive.org/web/20070830082729/http://www.aarnet.edu.au/library/aarnet_annual_report_2004.pdf |url-status=dead |archive-date=30 August 2007 |publisher=AARNet |access-date=8 November 2013 }}</ref>
* AARNet-operated layer 3 routers; two physically diverse PoPs in each capital city
* national backbone: AARNet-operated optical fibre transmission capacity
* AARNet-operated international fibre transmission capacity
* Also delivers enduser [[Layer 1]] optical transmission and [[Layer 2]] [[VLAN]] switching services

AARNet4 (2013–present): The AARNet optical network grows:<ref>{{cite web|title=What will AARNet4 enable our customers to do?|url=http://news.aarnet.edu.au/what-will-aarnet4-enable-our-customers-to-do/|publisher=AARNet|access-date=19 October 2014}}</ref>
* entirely AARNet-operated
* national optical backbone: optical fibre transmission capacity ultimately 80&nbsp;wavelengths each at 100&nbsp;Gbit/s (total 8&nbsp;Tbit/s)
* national IP network: 100&nbsp;Gbit/s layer&nbsp;3 routed network via diverse paths
* international connectivity: 240&nbsp;Gbit/s of optical fibre transmission capacity, via six network interconnect points in USA and one in Singapore
* enduser services: layer&nbsp;1 point-to-point optical transmission; layer&nbsp;2 [[Metro Ethernet|metro-Ethernet]] VLAN; layer&nbsp;2 and layer&nbsp;3 [[Multiprotocol Label Switching|MPLS]]-based [[Virtual private network|VPN]] services; high performance layer&nbsp;3 routed access to global research and education (R&E) networks and the public Internet
