Our free IPv6 ping tool lets you test IPv6 connectivity and measure network latency from anywhere. It sends ICMPv6 echo requests to an IPv6 address and returns real-time results like round-trip time and packet loss. As the internet transitions from IPv4 to IPv6, validating IPv6 reachability is essential for admins and developers managing modern infrastructure. Use this tool to verify a server is reachable over IPv6, diagnose routing and firewall issues, and compare performance between networks. Because this is web-based, you can test IPv6 targets even if your local network is IPv4-only. No registration required just enter an IPv6 address and start testing.
Quick test examples (plain text)
Try these known public IPv6 targets:
- Google DNS: 2001:4860:4860::8888
- Cloudflare DNS: 2606:4700:4700::1111
- Quad9 DNS: 2620:fe::fe
- OpenDNS: 2620:119:35::35
IPv6 Ping Test
How to use the IPv6 ping tool
- Enter an IPv6 address (compressed format like 2001:db8::1 is fine).
- Click “Ping IPv6”.
- Review success/timeout, latency in milliseconds, and overall stability.
- If results fail, verify routing, firewall rules, and whether the target allows ICMPv6.
Understanding ping results
| Metric | What it means |
|---|---|
| Time (ms) | Round-trip latency (lower is better) |
| Timeout | No reply received (ICMPv6 blocked, no route, host down, or ignores ping) |
| Consistency | Stable times indicate reliable connectivity; large spikes suggest congestion/jitter |
IPv4 vs IPv6 ping
| Aspect | IPv4 | IPv6 |
|---|---|---|
| Example | 8.8.8.8 | 2001:4860:4860::8888 |
| Protocol | ICMPv4 | ICMPv6 |
| Common pitfall | NAT hides hosts | Firewall/ICMPv6 filtering, immature routing on some ISPs |

Troubleshooting IPv6 ping issues
- Verify the target actually has IPv6 (AAAA record) using DNS Records Lookup.
- If everything times out, your ISP/router may not provide IPv6, or ICMPv6 may be filtered.
- If IPv4 works but IPv6 fails, the server may be misconfigured for IPv6 or blocked by firewall rules.
- For deeper diagnosis, check reverse DNS with Reverse DNS Lookup and ownership with IP WHOIS Lookup.
- To verify service ports, use Port Scanner.
Common Questions
What is IPv6 ping and why is it important?
IPv6 ping tests reachability and latency to an IPv6 address using ICMPv6 echo requests. It’s important because IPv6 is the long-term replacement for IPv4, and many services now run dual-stack (IPv4 + IPv6).
What’s the difference between IPv6 ping and IPv4 ping?
IPv4 ping uses ICMPv4 and targets 32-bit IPv4 addresses (like 8.8.8.8). IPv6 ping uses ICMPv6 and targets 128-bit IPv6 addresses (like 2001:4860:4860::8888). The concept is identical, but the protocol and address format differ.
Can I ping IPv6 addresses if I only have IPv4?
Yes—this web tool pings from our server, so you can test whether a target is reachable over IPv6 from the internet even if your local network is IPv4-only.
What does request timeout mean?
A timeout means the echo request was sent but no reply was received in time. Common causes include firewalls blocking ICMPv6, no IPv6 route, incorrect address, or the target host configured to ignore ping.
Is it normal for IPv6 to be slower than IPv4?
Not necessarily. Native IPv6 often performs similarly to IPv4. However, some networks have suboptimal IPv6 routing or tunnels that add overhead, which can increase latency.
What are link-local IPv6 addresses (fe80::)?
Link-local addresses (fe80::/10) only work on the local network segment and aren’t routable on the public internet. You generally can’t test link-local addresses from a web-based ping tool.
