How to check IPv6 configuration?

To check your IPv6 configuration, you can use the following commands depending on your operating system:

On Linux

1. Check IPv6 Status:

   sysctl net.ipv6.conf.all.disable_ipv6
   

   A value of 0 means IPv6 is enabled, while 1 means it is disabled.

2. View Network Interfaces:

   ip -6 addr show
   

   This command lists all network interfaces and their assigned IPv6 addresses.

3. Check Routing Table:

   ip -6 route show
   

   This command displays the IPv6 routing table.

On Windows

1. Check IPv6 Status: Open Command Prompt and run:

   netsh interface ipv6 show interfaces
   

2. View IPv6 Addresses:

   ipconfig
   

   Look for the "IPv6 Address" under your network adapter.

3. Check Routing Table:

   route print
   

   This will show the routing table, including IPv6 routes.

On macOS

1. Check IPv6 Status: Open Terminal and run:

   sysctl -a | grep net.inet6
   

2. View Network Interfaces:

   ifconfig
   

   Look for inet6 entries under your network interfaces.

3. Check Routing Table:

   netstat -rn -f inet6
   

Summary

These commands will help you verify if IPv6 is enabled and configured correctly on your system. If you find that IPv6 is disabled, you can enable it using the appropriate system settings or commands. If you need further assistance, feel free to ask!
