Neither IPv4 nor IPv6 is universally faster or more reliable. They can take different routes to a service, and performance depends on your internet provider, destination, routing, and whether IPv6 is working correctly. Broad measurements show IPv6 with slightly lower average latency worldwide, but also somewhat higher connection failure; neither finding predicts what you will see on your own connection. To compare fairly, test both address families from the same device and network to the same service.
Is IPv6 faster than IPv4?
Sometimes, but not as a general rule. The IETF’s RFC 9386 says a definitive answer cannot be given across use cases: IPv6 can perform better for one application or route while IPv4 performs better for another. Its summary describes worldwide average latency as slightly favoring IPv6, while average IPv6 connection failure remains somewhat worse. These are population-level observations, not a forecast for a particular home, provider, or website. Read RFC 9386.
Latency is only one aspect of connection quality. A low round-trip time (RTT) does not by itself establish high throughput, reliable connections, low packet loss, or a responsive application. Measure those separately.
Why can IPv4 and IPv6 perform differently?
They may take different routes
IPv4 and IPv6 use separate routing paths, and the routes do not necessarily have the same transit providers or peering links. A destination may also direct the two address families to different service locations. APNIC’s 2020 study of dual-stack RIPE Atlas probes and anycast sites found that 80% of probes mapped to the same anycast site over IPv4 and IPv6. Across the studied sites, 70% saw lower performance for IPv6; about 20% of those sites had RTT variance where IPv6 was more than 20 ms slower. This was a specific study of anycast sites and probes, not a current estimate for the whole Internet. The differences narrowed when the study constrained measurements to one continent or network. See APNIC’s study.

The endpoint or network may handle one family differently
An IPv6 address can be unreachable because of routing instability, endpoint configuration, or firewall behavior, even while the corresponding IPv4 service works. In dual-stack use, software may receive both an A record (IPv4) and an AAAA record (IPv6) and choose a connection based on timing. Happy Eyeballs, specified in RFC 8305, is designed to favor IPv6 when access times are comparable. An application’s chosen path is therefore not automatically a controlled comparison of both.
Tunnels and packet sizing can matter
IPv6 may be native, or it may travel through a tunnel such as Teredo or 6to4; those paths can behave differently. Packet handling also differs: IPv4 routers can fragment packets in transit, while IPv6 routers do not. If an IPv6 packet is too large for a link, the router should send an ICMPv6 Packet Too Big message so the sender can adjust packet size or fragment before retransmitting. APNIC has reported fragmented-packet drop examples of 20% in Japan, 1% in India, and 6% in China in its 2025 article. Those are geographically specific observations from that measurement, not current rates for every network or evidence that IPv6 is inherently unreliable. APNIC explains its measurement method.

What does “connection quality” mean?
Use the metric that matches the problem. A TCP handshake failure means a connection attempt did not complete; it is not a direct measurement of packet loss. RFC 9386 distinguishes these measures. For a useful comparison, track:
- Connection success: whether the same service endpoint can be reached over each address family.
- Connection time and RTT: how long establishment takes and how quickly packets make a round trip.
- Packet loss: measure directly with a suitable test; do not infer it from TCP handshake failures.
- Throughput: test separately, since a faster handshake or lower RTT does not prove faster downloads or uploads.
- Application response: record whether the specific site or app feels slow, rather than treating one service as representative of all traffic.
- Path context: note the provider, destination, test time, and whether IPv6 is native or tunneled.
How to test IPv4 versus IPv6 fairly
- Use the same setup. Keep the client device, Wi-Fi or Ethernet connection, destination, and test period constant. Confirm that the destination supports both address families.
- Collect separate IPv4 and IPv6 results. Use a diagnostic that records both paths. If a browser or app automatically selects one, its chosen connection alone is not a head-to-head test.
- Repeat the measurements. Compare connection success and RTT over multiple attempts, and record the time window. Network routes and service endpoints can change.
- Test other symptoms independently. If the concern is slow downloads, measure throughput; if it is a particular app, test that same service. Do not use RTT as a substitute for either.
- Interpret the scope correctly. A result from your device describes that device, network, and destination. Country-level maps and global averages describe groups of observations, not your individual connection.
APNIC’s live V6/V4 Relative Performance Maps compare observed TCP SYN exchange RTTs from dual-stack devices. For the 30-day window from September 1 through September 30, 2026, inspected October 5, 2026, the dashboard recorded the best observed IPv4 and IPv6 TCP SYN exchange RTT per device, then averaged IPv6 RTT minus IPv4 RTT. A negative value means IPv6 was faster in that comparison; a positive value means IPv4 was faster. The displayed country averages are not individual predictions, and the dashboard is live, so its window changes. View the APNIC performance maps.

Why is my IPv6 ping higher, or why does IPv6 fail while IPv4 works?
A higher IPv6 ping can reflect a longer or less direct route, a different service edge, or a temporary routing condition. It does not establish that IPv6 is always slower. If IPv6 attempts fail while IPv4 succeeds, first determine whether the issue affects one destination or multiple services, and whether the IPv6 path is native or tunneled. Then investigate provider routing, firewall rules, endpoint reachability, and—when symptoms point to oversized packets—ICMPv6 Packet Too Big handling.
These are possible diagnostic areas, not a diagnosis of your network. An APNIC Labs site tracker can help a site operator characterize visitor capability and connection results, including IPv4-only, IPv6-only, and dual-stack clients; successful and failed connections; average connection delay; and native versus tunneled IPv6 traffic.

What the large-scale measurements can—and cannot—tell you
APNIC Labs says its deployment measurement has run daily since 2012 and is configured to present 25 million to 30 million ad impressions per day (APNIC Labs, 2025). It infers client capability through known URL fetches and server-side DNS, web-fetch, and packet-capture observations; it does not instrument the user’s browser. Its sample is not geographically uniform, and APNIC weights per-economy data against user counts using UN Statistics Division and ITU-T data. Those design details help explain why aggregate findings are useful for broad trends but cannot settle which protocol is best on a particular connection. Read APNIC’s methodology.
