IPv6 Test
Check whether your network supports IPv6, view your IPv6 address, and verify dual-stack connectivity.
What Is IPv6?
IPv6 replaces the limited IPv4 address pool with 128-bit addresses — essential as more devices connect to the internet.
This ipv6 test page detects your public IPv4, attempts IPv6 address detection, and reports dual-stack status — a quick ipv6 checker for home and office networks on VSPIC.
How to Use This Tool
- Open the page — the test runs automatically on load.
- Wait for IPv4 and IPv6 detection to complete.
- Read the IPv4 and IPv6 address panels and status badges.
- Check Connection Type: Dual-Stack, IPv4 Only, or Unknown.
- If IPv6 is missing, review router and ISP steps in the guide below.
What Does This IPv6 Test Check?
The tool automatically tests:
- IPv6 Connectivity
- Whether a global IPv6 address is reachable from your browser.
- IPv6 Address Detection
- Your public IPv6 when the network provides one.
- Dual-Stack Support
- IPv4 and IPv6 both active (Dual-Stack) vs IPv4-only.
- Network Configuration
- High-level hint if ISP or router may block IPv6.
IPv4 vs IPv6
| Factor | Comparison |
|---|---|
| Address Space | IPv4 ~4 billion addresses vs IPv6 virtually unlimited |
| Performance | Similar when routed well; IPv6 can avoid some NAT overhead |
| Security | Both need firewalls; IPsec was optional in IPv6 design |
| NAT Requirements | IPv4 often needs NAT at home; IPv6 can use end-to-end addressing |
| Future Scalability | IPv6 required for long-term internet growth |
What Is Dual-Stack Networking?
Dual-stack hosts speak IPv4 and IPv6 simultaneously. DNS may return A and AAAA records; clients try both (Happy Eyeballs).
Our dual stack test labels your session Dual-Stack, IPv4 Only, or Unknown based on detected addresses.
Why IPv6 Matters
Carriers and cloud providers deploy IPv6 to scale IoT, mobile, and enterprise workloads. Sites without AAAA records still work via IPv4 but may miss IPv6-only users eventually.
ipv6 connectivity test results help before enabling AAAA DNS or firewall rules.
Benefits of IPv6
- Larger address space — no exhaustion like IPv4.
- Improved routing — flatter global tables at scale.
- Better network efficiency — reduced reliance on carrier-grade NAT.
- Future internet growth — required for billions of new devices.
Common IPv6 Problems
- ISP does not support IPv6 — plan shows IPv4-only upstream.
- Router misconfiguration — IPv6 disabled in LAN settings.
- DNS issues — missing or wrong AAAA records for services.
- Firewall restrictions — blocking ICMPv6 or specific ports.
How to Enable IPv6
Enable IPv6 on your network edge and devices when your ISP supports it:
Windows
- Confirm ISP offers IPv6 on your plan.
- Settings → Network → adapter → IP settings — ensure IPv6 is enabled.
- Reboot router after ISP enables delegation.
Linux
- Check addresses with ip -6 addr.
- Enable accept_ra and DHCPv6 or static config per distro docs.
- Ensure firewalls allow ICMPv6 neighbor discovery where needed.
macOS
- System Settings → Network → Details → TCP/IP — configure IPv6 Automatically.
- Restart router if no global address appears.
Home Routers
- Enable IPv6 in WAN/LAN settings (DHCPv6-PD or static).
- Update firmware — older units lack stable IPv6.
- Publish AAAA records only after this ipv6 address test succeeds.
Understanding IPv6 Test Results
IPv4 Active with IPv6 Supported means dual-stack — ideal for modern hosting.
IPv4 only with No IPv6 means your browser could not reach an IPv6-only detection endpoint — check ISP and router.
Results reflect your current network path, not every app on the device.
Common IPv6 Use Cases
- Modern web hosting — AAAA records alongside A.
- Cloud infrastructure — VPC IPv6 subnets and load balancers.
- Enterprise networks — dual-stack internal apps.
- IoT devices — large address space for sensors.
Benefits of Using This Tool
- Free ipv6 test online — no download.
- Shows IPv4, IPv6, and connection type in one view.
- Helps before DNS or firewall changes.
- Complements What Is My IP and DNS tools.

Frequently Asked Questions
IPv6 is the newer Internet Protocol with a vastly larger address space than IPv4, written as colon-separated hexadecimal groups.
IPv4 still works for most users, but IPv6 improves long-term scalability and is required on some modern networks and mobile carriers.
Yes — dual-stack networks run both protocols side by side. This tool reports whether your connection currently has both.
Some ISPs lag on deployment or disable IPv6 on certain plans. Router firmware and ISP support tickets can help.
Speed depends on routing and ISP — not the version alone. IPv6 can reduce NAT overhead when natively supported.
Dual-stack means your device and network can use IPv4 and IPv6 at the same time, choosing the best path per destination.
Sometimes — fewer NAT layers and modern routing — but DNS, firewalls, and broken v6 paths can also cause issues until configured correctly.
