@linuxfoundation Today I stumbled an article instructing users how to subnet a /64 prefix. Please don't recommend users do this. RFC 5375 makes it very clear that /64 is the min subnet size. RFC 7421 details every that breaks by using longer prefixes.https://www.linux.com/learn/intro-to-linux/2017/10/calculating-ipv6-subnets-linux …
So while an interesting article showing useful tools, @linuxfoundation please update to provide some note that informs users that while they can gain some usability with internal /120 prefixes, they also lose out on a lot. Users need to pressure ISPs to implement IPv6 correctly.
