With default settings from Gentoo handbook, it is easy to work with dualstack IPv4 + IPv6, if corresponding network settings are made.

This how-to describes how to work with IPv6 only, without IPv4 address on the network interface.

Internet connection
Check IPv6 connection works properly:

Check the router answer with ICMPv6 router Discovery tool (from ):

Gentoo mirrors
Check if mirror(s) are accessible by IPv6.

Reboot the OS?

NAT64 and DNS64
These services are needed to reach IPv4-only resources.

More information: https://en.wikipedia.org/wiki/NAT64, https://en.wikipedia.org/wiki/IPv6_transition_mechanism#DNS64

It is possible to setup your own NAT64 and DNS64 stack.

Also, it is possible to use some public service, for example https://www.trex.fi/2011/dns64.html :

How to check
Check OS updating work.

Check web-sites in the web-browser.

Check IM software works.
