IPV4 Sub netsTutorial

Start > CMD > ipconfig

IPV6 Addresses was introduced to provide large address space

IPv6 Testing Tools

Check your IPv6 address formatting is correct
Check your IPv6 connectivity from this website (Sydney)
Check your IPv6 connectivity from (USA)
Check Internet Service Provider IPv6 readiness
For full IPv6 connectivity, service providers need to set up IPv6-addressed nameservers, AAAA ('quad-A') address records, AAAA mail exchange records and allow website access over IPv6.
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.
