User:Vazhnov/Knowledge Base:IPv6 only

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:

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

Get GENTOO_MIRRORS:

Check: both

Get rsync mirrors:

Network interface
Example:

Known issues

DNS settings
is needed to update DNS settings in by information from the router via RDNSS (router advertisement DNS).

Apply
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.
