Australia Internet Overview
The Australian internet is built around the National Broadband Network (NBN), a wholesale network. Retail Service Providers (RSPs) buy access to this setup and sell it to consumers. Because traffic routes through main exchange hubs in capital cities like Sydney, Melbourne, and Brisbane, users in regional areas might sometimes show up as being located in a nearby capital city.
Does Your IP Address Change?
Most home broadband and mobile connections in Australia get a dynamic public IP address, so it can change when your router reconnects or your provider reassigns it. Many mobile networks also put customers behind carrier-grade NAT, where one public address is shared. Static addresses are usually a paid business option.

Australia IP Address Space in Numbers
As of 25 September 2026, the regional internet registries list 46.1 million IPv4 addresses (46,089,216) as delegated to 2,785 organisations in Australia: 1.25% of all delegated IPv4 space, the 12th-largest share of any country. Organisations there also hold 1,739 IPv6 blocks and 3,000 autonomous system numbers (ASNs).

How to read these numbers
The registry figures count addresses delegated to organisations based in Australia. The network and city figures count the 56.9 millionIPv4 addresses that geolocate there, which is why the two totals differ. Large address blocks usually geolocate to the owner's headquarters or data centres, so a city's share reflects where networks are registered and hosted, not how many people are online there. Some big holders, such as government, university or corporate networks, are not consumer ISPs at all.

IPv6 Transition & Adoption
Next Generation Protocol Deployment
IPv6 adoption in Australia is growing but uneven between providers. RSPs like Telstra and Aussie Broadband have pushed native IPv6 support to new customers. For technical insights into how this interacts with global CDN networks, see our post on how CDNs work. Older residential networks and rural fixed-wireless setups are still transitioning from IPv4.
How to Use the Location Finder
Type the Australian IP address into the lookup box and run the search. The tool will display the state (such as NSW, VIC, or QLD), city, retail ISP, ASN, and coordinates. To look up your own connection, just click search with the box empty, or run a quick speed test to check connection throughput.
Submit IP/Domain
Type any valid IP or site domain in the input above.
Verify Details
Analyze ISP, geolocation state/city, coordinates and timezone records.
Audit Network
Utilize the returned metrics to troubleshoot latency or perform compliance checks.
Benefits of Australia IP Lookup
- Route users to the closest CDN server to lower latency across the Pacific and see network latency explained.
- Stay compliant with local laws, including the Australian Privacy Act, and understand what CGNAT is.
- Localize content for state-specific time zones and holidays using the state returned by the IP lookup, then check responsiveness from your servers with our ping checker.
- Trace and block out-of-country transactions to reduce credit card fraud.
