What Is My IP Address?

Your public IP address is the digital equivalent of your home address for the internet. Every device connected to the web is assigned one, a unique string of numbers that identifies you to every website, service, and peer-to-peer connection. For an Australian online casino player, this isn't just technical trivia. It's the foundational layer of your digital identity, affecting everything from game access and bonus eligibility to the security of your deposits and the scrutiny of your play. Knowing your IP is the first step in taking control of your online presence.

The tool on this page reads the connection request from your browser. It doesn't access your device. It simply reports back the IP address your traffic appears to be coming from, along with the inferred location, the Internet Service Provider (ISP) associated with that IP block, and details about your browser and system. It's a mirror held up to your internet connection.

IPv4 vs. IPv6: The Two Languages of the Internet

The internet is undergoing a silent, massive transition. IPv4, the old system, has about 4.3 billion addresses. We ran out. IANA allocated the final IPv4 blocks to regional registries back in 2011. IPv6 is the replacement, with a near-infinite pool: 340 undecillion addresses. That's a 34 followed by 37 zeros. For context, it's more than enough for every grain of sand on Earth to have its own unique IP. Australia's adoption is middling—around 30-40% as of 2024 according to APNIC stats—but it's climbing as the old system creaks.

Definition & Principle

An IPv4 address looks like 203.219.121.45. Four numbers from 0 to 255, separated by dots. An IPv6 address is more complex: 2001:0db8:85a3:0000:0000:8a2e:0370:7334. Eight groups of four hexadecimal digits, separated by colons. The core principle is the same: a unique identifier. But IPv6 isn't just more addresses; it's designed for a modern internet with built-in security features like IPsec and more efficient routing, which can mean lower latency. That matters for live-bet sports or real-time poker.

Comparative Analysis

For the average user, the difference is often invisible until it causes a problem. Most home networks and casinos are "dual-stack," meaning they handle both. But issues arise. Some older gaming clients or casino back-end systems might have poor IPv6 support. If your ISP (like many in regional Australia) has you behind CGNAT for IPv4 but gives you a native IPv6 address, your device might choose the IPv6 path by default. If the casino server you're connecting to in Malta or Curaçao has a flaky IPv6 route, your connection could be unstable. You might experience laggy spins or a dropped blackjack hand. Conversely, a pure IPv6 connection can sometimes bypass simplistic IPv4-based geo-blocks or throttling rules that an ISP hasn't updated.

Practical Application for Australian Players

Check which address our tool shows. If you see only an IPv4, your connection is legacy. If you see both, you're dual-stack. Here’s the scenario: You're in a Perth share house with five other people. Your ISP uses CGNAT. All six of you, plus all your devices, share one public IPv4 address. If two of you sign up to the same online casino from the same IP, their fraud system will likely flag it as potential multi-accounting. Your bonuses could be confiscated, accounts frozen. The solution? A quality VPN with Australian servers gives each of you a distinct IP, separating your traffic. But you must ensure the VPN supports IPv6 leak protection if the casino does, otherwise your real IPv6 might give you away. Frankly, for casino play, I often recommend disabling IPv6 on your device when using a VPN that doesn't explicitly handle it. It's one less variable.

Geolocation & ISP: Why Your Digital Suburb Matters

The geolocation data tied to your IP is not GPS. It's not pinpoint accurate. It's a best guess based on commercial databases that map IP blocks to a city, sometimes a postcode. These databases are updated from information provided by ISPs, user-submitted data, and network routing tables. The accuracy in major Australian cities can be within 50km. In regional or rural areas—think outback Queensland or the Kimberley—it can be off by hundreds of kilometres. Your ISP is the company that owns the block of IPs and provides you access. In Australia, that's typically Telstra, Optus, TPG, or a reseller.

Definition & Principle

When you connect, the casino or any website receives your IP. It then performs a reverse lookup against a geolocation database like MaxMind or IP2Location. These databases return a latitude/longitude, city, region, and often an ISP name. The site uses this to customise content, enforce licensing, and assess risk. It's a passive, constant check.

Comparative Analysis

Compared to other tracking methods like browser fingerprinting or cookie tracking, IP geolocation is relatively coarse and transient. Your IP can change if you reboot your home router (a dynamic IP) or if your ISP re-assigns blocks. Browser fingerprinting is far more persistent and unique. However, for regulatory compliance, IP geolocation is the first and most critical line of defence for casinos. A bookmaker licensed in the Northern Territory cannot legally offer live-betting to someone whose IP appears to be in Victoria, where the law differs. They will block you instantly. The alternative to IP-based blocking is manual document checks, which are too slow for real-time play.

Practical Application for Australian Players

You live in Albury, on the NSW/Victoria border. You sign up with a casino licensed in NSW. Our tool shows your IP geolocating to Wodonga, Victoria, because your ISP's network hub is there. The casino's geofence blocks you. This is a common headache. The fix isn't to argue with the casino's support. They use a third-party database; they won't change it for you. The fix is to use a VPN server located firmly within NSW. But caution: using a VPN to circumvent geolocation checks may violate the casino's terms of service. For accessing Australian-licensed sites from within Australia, it's generally low risk if you're simply correcting a database error. Using a VPN to appear from a different country to access a site not licensed here is a clear breach and will void any player protections. Dr Charles Livingstone, a leading Australian gambling researcher, notes the tension: "The enforcement of jurisdictional boundaries via IP address is crude but necessary under current licensing models. It creates friction for legitimate users while being trivially bypassed by determined actors." This friction is what you experience.

Your ISP matters too. Some casinos and game providers silently blacklist IP ranges from certain ISPs known for high fraud or originating from countries they don't service. If your Australian ISP uses an IP block previously assigned to, say, Southeast Asia, you might find certain game providers' content simply won't load. A quick VPN speed test and connection through a different network can diagnose this.

The VPN & Proxy Check: Is Your Disguise Working?

You've subscribed to a VPN for privacy, or maybe to access an overseas poker site. You hit connect, choose "Sydney Server," and feel secure. But are you? VPN leaks are common. An IPv6 leak, a WebRTC leak, or a DNS request going outside the encrypted tunnel can all reveal your true IP and location to a casino's website. This tool is your litmus test. The moment you activate your VPN, refresh this page. The IP, geolocation, and ISP should change completely. If you still see your real Melbourne ISP, your VPN has failed.

Definition & Principle

A VPN (Virtual Private Network) encrypts your traffic and routes it through a server in a location of your choice, masking your real IP. A proxy server acts as a relay but often without full encryption. When working correctly, this page will show the IP of the VPN's exit server, not yours. The principle is substitution. You're borrowing a digital address for the session.

Comparative Analysis

Not all VPNs are equal for casino play. Free VPNs are a disaster. They have tiny server lists, are slow, and their IP addresses are often publicly listed in "VPN detector" databases used by casinos to block access. Premium VPNs with dedicated IP options or large, rotating IP pools are harder to detect. Compared to other privacy tools like the Tor browser, a VPN offers a better speed-to-anonymity ratio for real-time gaming. Tor introduces massive latency, making it useless for pokies or live casino. A proxy is even less suitable; it offers no meaningful encryption and is easily spotted.

Practical Application for Australian Players

You're an Australian player who also enjoys poker on an offshore site not licensed here. You use a VPN to connect via Singapore. You make a large withdrawal. The site's compliance team runs a check. They see your account is constantly accessed from a known commercial VPN IP range. This is a red flag for money laundering or bonus abuse. They may delay your payout, demand additional KYC, or even confiscate funds citing terms violation. Professor Sally Gainsbury of the University of Sydney's Gambling Treatment and Research Clinic highlights the risk: "Players using technical means to access prohibited sites are operating outside the consumer protection frameworks. Any dispute becomes immensely difficult to resolve, and the financial loss can be total." The VPN check isn't just about functionality; it's about understanding the risk profile you adopt when you mask your IP from a gambling provider.

To properly check: Enable your VPN. Refresh this page. Verify the IP and location changed. Then, go to a site like "ipleak.net" which performs more aggressive tests for WebRTC and DNS leaks. Only then should you log into a casino. And frankly, if you're playing on a properly licensed Australian site, you shouldn't need a VPN for privacy from the casino itself. Their license requires data protection. You're using it for privacy from your ISP or other third parties.

User Agent & Connection Details: Your Browser's Fingerprint

Alongside your IP, every request your browser sends includes a "User Agent" string. It's a dense line of text identifying your browser, its version, your operating system, and sometimes device model. It looks like technical gibberish but is used for compatibility. A casino site uses it to serve you a mobile-optimised version if you're on iPhone, or a desktop client if you're on Windows. But in the hands of fraud prevention systems, it becomes one more data point to build a unique fingerprint of your device.

Definition & Principle

The User Agent is sent in the HTTP header. It's passive and automatic. Our tool decodes it to show you what you're broadcasting. Connection details inferred from your IP (like the potential presence of a proxy) are based on known network characteristics and lists of suspicious IPs.

Comparative Analysis

Compared to your IP, which can change, your User Agent is more stable but also easier to spoof. Browser extensions can change it. However, advanced fingerprinting looks at dozens of attributes: screen resolution, installed fonts, timezone, hardware concurrency. Changing just your User Agent is like putting on a fake moustache while your height, gait, and voice remain the same. It's a superficial change. For casinos, mismatches raise flags. If your IP is from a Sydney VPN, but your User Agent reports a timezone of GMT+2 (South Africa), their system will note the anomaly.

Practical Application for Australian Players

You have two accounts—one for sports betting, one for casino—at the same licensed Australian operator. This is allowed. But you use the same laptop for both. You log into the sports account, place a bet. An hour later, you log into the casino account to claim a deposit bonus. Their fraud system doesn't just check IP. It creates a device fingerprint from your User Agent, screen specs, and other browser data. It sees the same device accessing two accounts. This could trigger a review to ensure you're not circumulating bonus wagering requirements across accounts, which is prohibited. It's not an instant ban, but it adds to your risk profile. If you were to then connect via a VPN from a different country on the same device, the fingerprint remains consistent while the IP jumps continents. That's a major red flag.

My advice? Be consistent. If you're going to use a VPN for privacy, use it all the time with that site. Don't flip-flop between your real IP and a VPN IP on the same account. It looks like account sharing or selling. And clear your browser cache or use separate browser profiles if you genuinely manage multiple legitimate accounts within a household. It helps differentiate the device fingerprints.
