What a Adelaide IP address tells you
Adelaide is the one Australian city here where colocation outweighs public peering. Twelve facilities hold 117 network presences, led by DigiCo Adelaide ADL2 with 38, NEXTDC A1 with 22, Colocity DC3 with 20 and Equinix AE1 with 13, while the five exchanges together account for 103 peer records. Those exchanges are small and evenly matched, EdgeIX Adelaide on 36 participants and IX Australia Adelaide (SA-IX) on 35, then MegaIX Adelaide on 22, BGP.Exchange Adelaide on nine and HSIX-SA on one. No Australian mobile ASN appears on any of them.
An address that geolocates to Adelaide points at how the block is registered rather than where the equipment sits. Telstra (AS1221), Optus (AS4804) and Vodafone Australia (AS133612) announce address space from registry records that each carry a single published address, and mobile traffic leaves through a limited number of gateways. Geolocation databases take the operator's published location for a prefix, so a block covering South Australia can resolve to Adelaide no matter where the subscriber using it happens to be.
Checking the origin ASN and the netname on the covering prefix answers more than a city lookup. If the prefix originates from one of the three mobile ASNs, the address is subscriber access and the city label is registration detail. If it originates from a network present in DigiCo Adelaide ADL2 or NEXTDC A1, there is a building behind it. The counts on this page describe network presence in Adelaide and carry no information about where a person is.
Mobile carriers in Australia
A mobile address in Adelaide is routed by one of the country's operators. Each entry lists the operator's ASNs, so you can check which network an address belongs to.
Questions
Which internet exchanges are in Adelaide?
PeeringDB lists five. EdgeIX Adelaide has 36 participants, IX Australia Adelaide (SA-IX) 35, MegaIX Adelaide 22 and BGP.Exchange Adelaide nine, with HSIX-SA on one. Adelaide holds 103 peer records, the fewest of the Australian cities covered here.
Do Australian mobile carriers peer in Adelaide?
No Adelaide exchange lists Telstra (AS1221), Optus (AS4804) or Vodafone Australia (AS133612) as a participant. With 117 network presences across twelve facilities against 103 peer records, more of Adelaide's interconnection happens inside buildings than on public exchange fabric.
Does an IP that geolocates to Adelaide mean the device is there?
No. Geolocation databases follow the location an operator publishes for a prefix, and mobile networks route subscribers through a small number of gateways. An Adelaide result tells you which registry record covers the address, and the origin ASN tells you what kind of network runs it.
