How to read your result

Each check shows a word as well as a colour. "Works" means a server that has only that kind of address answered and told us your address. "No reply" means your connection could not reach it within 4 seconds.

What the score means (our scoring)
Score	What you have	What to do
10 / 10	IPv6 works and your browser uses it first	Nothing. Sites with IPv6 reach you directly.
7 / 10	IPv6 works, but IPv4 was used	Usually nothing. Browsers pick whichever connects faster at that moment.
3 / 10	IPv4 only	Websites still work. Read "Your test shows no IPv6" below if you want it.

The round-trip times compare the same Cloudflare service over both protocols. A few milliseconds either way is normal. If IPv6 is much slower, your provider may route IPv6 traffic a longer way; a traceroute from your provider's network can show where the time goes.

IPv6 in India

IPv6 use in India is well above the world average. The Google IPv6 statistics page shows 68% of Google users in India connecting over IPv6 on 28 September 2026, against 46% worldwide.

APNIC Labs, which measures differently, found 77.67% of users in India IPv6-capable and 75.88% preferring IPv6 on 29 September 2026. Your own result depends on your provider, your plan and your router.

If you have IPv6, many big sites (Google, YouTube, Facebook, Netflix) reach you over IPv6 directly, without going through your provider's shared IPv4 NAT.

Your test shows no IPv6: what to do

If IPv6 works on mobile data but not on home Wi-Fi, the router may have IPv6 turned off. Look for an IPv6 setting on the router's page, or ask your provider whether IPv6 is enabled on your line.

Run this test once on mobile data and once on your Wi-Fi. That tells you whether the phone, the router or the line is the limit.
On the router's admin page, look for an IPv6 or "WAN IPv6" section. Names differ between models; if you change anything, note the old setting first.
Restart the router, wait until it is online again, and press Run again here.
Still no IPv6? Ask your provider's support whether IPv6 is available on your plan and area, and quote the result of this test.

Turn off any VPN before testing. Many VPN apps carry only IPv4 or block IPv6 on purpose, so the test reports no IPv6 while the VPN is on.

What affects IPv6 and the preferred protocol

Your network. Your provider must support IPv6 on your line, and your router must pass it to your devices.
VPNs and security apps. A VPN that ignores IPv6 can let IPv6 traffic bypass the tunnel. Compare the IPv6 address here with the VPN on and off: if it stays the same, IPv6 is leaking past the VPN.
How browsers choose. When a site has both kinds of address, browsers usually try IPv6 first and fall back to IPv4 quickly if it is slow, so the preference can change from one run to the next.
Firewalls. Office and school networks sometimes block IPv6 even when the provider offers it.

How this test works

Your browser asks two IPv4-only servers (Cloudflare's 1.1.1.1 and api.ipify.org) and two IPv6-only servers (Cloudflare's 2606:4700:4700::1111 and api6.ipify.org) which address they see. The first answer of the right kind counts; each request gives up after 4 seconds. A dual-stack server, api64.ipify.org, shows which protocol your browser picked. The browser, not this page, decides which one to use.

For the round-trip times, the page sends one warm-up request and then 5 timed requests to each Cloudflare address and shows the median. These are HTTPS timings in the browser, so they include a little processing time and are not the same as ping. The whole test uses well under 100 KB of data.

The readiness score (10, 7 or 3) is our own scoring, not a standard. Cloudflare and ipify see your IP address, as any site you visit does; nothing is stored by us. See what each service sees, the full method, and your ISP and location on the IP address page.

Questions about IPv6

How do I know if I have IPv6?

You have IPv6 when the IPv6 check above says "Works" and shows an address with colons. The test reaches a server that has no IPv4 address at all, so a pass cannot come from IPv4. Run it on each network you use, because mobile data and home Wi-Fi often differ.

Is IPv6 faster than IPv4?

IPv6 is not faster by itself; speed depends on the route each protocol takes through your provider. Compare the two round-trip times above. On some networks IPv6 also skips the provider's shared IPv4 NAT, so it takes a different path.

What is an IPv6 leak with a VPN?

An IPv6 leak happens when the VPN tunnels only IPv4, so sites that support IPv6 still see your provider's IPv6 address. Run this test with the VPN on: if the IPv6 check shows the same address as without the VPN, IPv6 bypasses it. Turn on the VPN app's IPv6 or leak protection, or ask its support.

Why does IPv6 work on my phone but not on my laptop?

The phone on mobile data uses your mobile provider's network, while the laptop uses your home router and broadband line. If the IPv6 check passes only on mobile data, the home router or the broadband line is the missing link, not the laptop.

Should I turn IPv6 off?

Usually no. Websites work over both, and your browser falls back to IPv4 when IPv6 fails. Turn it off only as a short test when a specific app misbehaves, and switch it back on afterwards.
