IPLeak.net vs HackMyIP: Which Finds More Leaks? (2026)
Short answer
For pure leak testing, IPLeak.net checks more. When we checked both sites on 25 October 2026, IPLeak.net ran a real DNS leak test, a torrent client IP test and a WebRTC test on one page. HackMyIP has a WebRTC leak test too, but its DNS leak page only checks that public DNS resolvers are reachable, and it has no torrent tracker. HackMyIP is the broader toolkit: a VPN and proxy check, a browser fingerprint estimate, a real port check, an email breach check and a free no-key API.
Checked on 25 October 2026 with curl: ipleak.net's homepage, its page scripts, its JSON and XML API and its DNS and torrent detection endpoints, plus HackMyIP's own tool pages. Both sites can change, so re-test before relying on a single row.
Feature comparison
| Check | IPLeak.net | HackMyIP |
|---|---|---|
| DNS leak test (which resolvers answer your lookups) | Yes. Lists the resolvers that answered its unique test lookups | No. Its DNS page only checks that DNS-over-HTTPS resolvers are reachable |
| Torrent client IP | Yes. Magnet link with its own tracker, which records what your client announces | No. Browser-level checks only, no tracker |
| WebRTC leak test | Yes | Yes (/webrtc) |
| IPv4 and IPv6 address | Yes (separate IPv4 and IPv6 test hosts) | Yes (the homepage shows your second address when your browser has one) |
| IP details | ISP, ASN, network, country, registered country, city, accuracy radius (partly MaxMind data) | ISP, ASN, city, time zone, IP type |
| VPN / proxy / datacenter verdict | Only whether the IP is an AirVPN server | Yes (/proxy), plus a proxy-header check |
| Tests on alternative ports | Yes (8000 and 62222) | No |
| Browser geolocation (location permission) test | Yes | No (IP-based location only) |
| Browser fingerprint | Shows browser, screen and header details | Yes, with an estimated uniqueness percentage (/fingerprint) |
| Open port check, email breach check, IP blacklist check | No | Yes (/ports, /breach, /blacklist) |
| Free API, no key | Yes. JSON, XML or PHP; IP and domain lookups, DNS detection | Yes. JSON; IP lookup, DNS, WHOIS, reverse DNS, blacklist and more (/api) |
| Third-party analytics on the page | None. Its page loads only its own scripts | Google Analytics |
| Languages | English | English, Simplified Chinese, Traditional Chinese |
Where IPLeak.net is better
A real DNS leak test. IPLeak.net makes your browser look up unique test names and lists every resolver that answered. When we called its detection endpoint, it returned the resolvers our test connection really used, which is what a DNS leak test should show. HackMyIP's DNS page says itself that it cannot tell which resolver your system uses.
Torrent client IP. IPLeak.net gives you a magnet link whose tracker runs on ipleak.net, so it records the IP your torrent client actually announces. HackMyIP's torrent page runs browser-level checks only and says it receives nothing from your client.
More connection angles. The site also answers on ports 8000 and 62222 to catch routing that depends on the destination port, offers a browser geolocation test, and shows the IP's registered country and an accuracy radius.
No third-party analytics. The ipleak.net page loads only its own scripts, and its Content-Security-Policy allows no outside script sources. HackMyIP uses Google Analytics.
Where HackMyIP is better
VPN and proxy verdict. HackMyIP's VPN and proxy check classifies your IP as VPN, datacenter or residential from network data and checks proxy headers. IPLeak.net only tells you whether the IP belongs to AirVPN, the VPN provider behind the site.
Fingerprint estimate. The fingerprint test gives an estimated uniqueness percentage. IPLeak.net lists browser, screen and header details without a score.
Checks IPLeak.net does not have. A real server-side open port check (it reported port 22 open and port 23 closed on scanme.nmap.org in our test), an email breach check, an IP blacklist check against 12 DNSBLs, plus WHOIS and DNS record lookups.
A broader no-key API. Both have a free API without a key. HackMyIP's JSON API also covers DNS, WHOIS, reverse DNS and blacklist checks; IPLeak.net's covers IP and domain lookups and DNS detection, in JSON, XML or PHP.
Chinese versions. HackMyIP's core tools are also available in Simplified and Traditional Chinese.
Which one should you use?
Testing a VPN for leaks: start with IPLeak.net, which covers DNS, torrent and WebRTC leaks on one page. Then use HackMyIP to see whether sites will flag your VPN IP, how unique your browser looks, and whether any ports are open. The two work well together.
Frequently Asked Questions
What is the difference between IPLeak.net and HackMyIP?
IPLeak.net is a one-page leak tester from AirVPN: it checks DNS, WebRTC and torrent client leaks and shows your IP details. HackMyIP is a wider privacy toolkit with a WebRTC leak test, a VPN and proxy check, a fingerprint estimate, port, breach and blacklist checks, and a free JSON API. On 25 October 2026 HackMyIP had no real DNS or torrent leak test.
Is IPLeak.net or HackMyIP better for a DNS leak test?
IPLeak.net. It lists the DNS resolvers that answered its unique test lookups, which is how a DNS leak test works. HackMyIP's DNS page only checks that public DNS-over-HTTPS resolvers are reachable and says it cannot detect a DNS leak.
Can HackMyIP see my torrent client's IP like IPLeak.net?
No. IPLeak.net's magnet link points your torrent client at its own tracker, which records the IP the client announces. HackMyIP runs no tracker, so its torrent page checks only your browser's IP and WebRTC.
Does IPLeak.net have an API?
Yes, without a key: put json, xml or php in the path, for example ipleak.net/json/8.8.8.8, and it also has a DNS detection API. HackMyIP's free API returns JSON for IP lookup, DNS, WHOIS, reverse DNS, blacklist checks and more.
Is HackMyIP a good IPLeak.net alternative?
For leak testing, not a full one: use IPLeak.net for DNS and torrent leaks. HackMyIP is a good companion for what IPLeak.net does not do, such as VPN and proxy detection, fingerprinting, and port and breach checks.
