Victoria · network infrastructure

Melbourne holds the two buildings that account for most of the state's network presences: NEXTDC M1 with 141 networks and Equinix ME1/ME2 with 135. After those the counts drop quickly. NEXTDC M2 in Tullamarine has 34 networks, Vocus Melbourne MEL03 has 24 and the 5GN Melbourne Data Centre has 16, while sites in Derrimut, West Footscray, Mitcham and Deer Park sit in the single digits. All six of the state's exchanges are in Melbourne, so a network with 389 presences to reach can do it inside one metropolitan area.

A Victorian address block is Victorian because the operator holding it published a Victorian address on its registry record. Geolocation databases read the registration, not the cable. Mobile traffic is aggregated further still: Telstra announces its mobile subscribers from AS1221, Optus from AS4804 and Vodafone Australia from AS133612, and each carrier routes handsets through a small number of regional gateways. A device on the edge of the state can appear in Melbourne, and a device in another state can appear in Victoria, without either address being wrong.

The prefix carries better evidence than the country or state field. Look at the origin ASN, which names the network announcing the route, and at the netname and registered address on the object covering that prefix. The state's 389 network presences and 386 peering networks include colocation customers, transit carriers and mobile gateways under the same state label, and the registry object is what separates one from another.
