DNS Leak Test

DNS leak test: who sees your lookups?

Every site you visit starts with a DNS lookup. If it goes to your ISP, your provider can see where you browse. This check reads the network your connection exits through — an honest, in-browser signal of whether your DNS is exposed.

Indicative check. A browser can’t list your operating system’s DNS resolvers directly, so this reads the network your connection exits from. If that’s your ISP, your DNS is almost certainly exposed too. For a definitive audit, run a dedicated DNS test with your VPN on and off.

Why it matters

Why a DNS leak exposes your browsing

Your DNS lookups are a log of every site you open. Want the full picture of what your connection reveals? Check your IP.

Your ISP sees every site

A DNS lookup happens before you load any page. If it goes to your ISP's resolver, your provider has a running list of the domains you visit.

It leaks around VPNs

Some setups tunnel your traffic but still send DNS requests outside it. Your IP looks hidden while your lookups quietly reveal where you go.

It's tied to your location

The network your DNS exits through pins you to a region and provider — the same context this check reads from your connection.

It undermines private browsing

Incognito clears local history, not DNS. The resolver still sees your queries, so "private" browsing isn't private from your provider.

How to test

Run the DNS leak test in three steps

  1. 1

    Read your context

    The check shows the network and ISP your connection exits through. If that's your own ISP, your DNS is almost certainly exposed too.

  2. 2

    Turn your VPN on

    Connect your VPN and reload. The exit network should change to the VPN's — a sign your DNS is being rerouted with your traffic.

  3. 3

    Confirm with a full test

    For a definitive check, run a dedicated DNS test with your VPN on and off and compare the resolvers that appear.

The honest bit

Free because Premium pays the bills — never because we sell your data

The usual catch with a free VPN is that it logs and sells your browsing to make money. Zippa doesn’t. Our free tier is funded by people who upgrade to Premium, and we keep a strict no-logs policy — we don’t record the sites you visit, your real IP, or your DNS queries. There’s simply nothing to sell.

FAQ

Frequently asked questions

The questions people actually ask before they install — answered plainly.

  • DNS is the system that turns a domain name like example.com into an IP address. A DNS leak happens when those lookups are sent to your ISP's resolver instead of through your VPN — so even with the VPN on, your provider can still see the list of sites you're visiting.

  • A web page can't read your operating system's DNS resolvers directly, so rather than fake a result, this check reads the network your connection exits through using our own server. If that network is your own ISP, your DNS lookups are almost certainly exposed too. It's an honest, indicative check — we're upfront that it's a signal, not a full audit.

  • Browsers are sandboxed and deliberately don't expose your system's DNS configuration to web pages, for security reasons. Truly enumerating your resolvers requires a specialised test that watches which servers request a unique hostname. This tool gives you the network context you can read safely in-browser, and tells you plainly what it can and can't prove.

  • Use a VPN that routes your DNS requests through the same tunnel as your traffic. Zippa's Chrome extension does this for your browser — your DNS lookups go through the location you pick, not your ISP's resolver, so your provider can't build a list of the sites you visit.

  • Yes. Zippa routes your browser's traffic and DNS together through the country you choose, so lookups don't slip out to your ISP. Combined with our strict no-logs policy, that means your queries aren't exposed to your provider and aren't recorded by us either.

  • It depends who runs it. Plenty of free VPNs pay their bills by logging and selling browsing data — that's the real catch. Zippa is funded by people who upgrade to Premium, not by your data, and we keep a strict no-logs policy, so there's nothing to record or sell in the first place.
