What ipv6 subnets are not routable on the internet?

Question

Network routing

I want to try switching to ipv6 inside my home local network. Question - where can I read which ipv6 ranges are not routable on the Internet and are suitable for use on a LAN?

Answer 1

Primary source what addresses are for what https://www.iana.org/assignments/ipv6-address-spac... see comments and links to other documents, in particular addresses for various special cases https://www.iana.org /assignments/iana-ipv6-special...
Currently, only 2000::/3 networks can be routed on the Internet, and even then not all of them, many of them are not distributed yet. For a home network, it is correct to use a subnet from the range that the provider gave you, that is, if your LAN connects to the Internet, then its addressing depends on what address space the provider allocates for you - NAT does not exist.
If this is a 100% isolated network forever, then you need to use the addresses fd00::/8 which has the recommended structure within one LAN fdXX:XXXX:XXXX::/48 where X is a pseudo-random sequence, the rest is up to you.

Answer 2

FC00::/7
