IPv6 Testing Tools

IPv6, like any new technology, takes time to implement and operate. Here are some tools to make checking, tracing and verifying IPv6 easier for you.

Check your IPv6 connectivity from this website (Sydney)

• Ping an address or host using both IPv6 and IPv4
• Trace your network route to an IPv6 address or host

Check your IPv6 connectivity from ipv6-test.com (USA)

• Check your IPv6 and IPv4 connectivity
• Compare the ping latency (speed) of your IPv4 and IPv6 connectivity from sites around the world
• Compare the broadband speed of your IPv4 and IPv6 connectivity from sites around the world

Check your IPv6 address validity

• What is my IPv6 address? If you're using IPv6 it will appear in the welcome message!
• Check if the IPv6 address you are using is valid and properly formatted IPv6

Check Internet Service Provider IPv6 readiness

For IPv6 connectivity, providers must set up IPv6-addressed nameservers, AAAA ('quad-A') address records, AAAA mail exchange records and allow website access over IPv6.

• Survey of IPv6 service readiness for universities, research orgs, cloud services, telcos, government sites and more
• Check IPv6 nameservers, AAAA & MX records and website (ready.chair6.net)
• IPv6 DNS, mail exchange and web connectivity (ip6-nl)
• AAAA records and web IPv6 connectivity (ipv6-test.com)

Check your IPv6 Path Maximum Transmission Unit

If a host sends IPv6 packets that are too big for part of its route, it should get a Packet Too Big message so it can re-transmit the data in smaller packets. If that message doesn't get back (e.g. firewalls, mis-configured routers) it can affect IPv6 connectivity.

• Check for Path MTU discovery problems (wand.net.nz)
