2 dhcpv6 in LAN (solved)

[stanthewizzard]

I listened

Everything is 2a01:cb00:c53:c5d6::xxxx (and some wiht fixed IP)

I can ping fd07:1972:2406:2014::4 from any host (after a windows server reboot it was ok)

Everything is now ok

I already linked to that indirectly, and expanded on that with a later post offering a practical demo.

So yes, IOW - overall this is a nice exercise in getting dual-stack working that will not be used anyway.

Everything is working now
thanks

Well, OK. It's working, just being unused.

Must be the idea of "private addresses" from IPv4 experience that misleads people to try to use ULA.

Probably, plus the stupid ISPs and changing prefixes. Making ULA less preferred than IPv4 in the stack somehow improved things here, at least using ULA does not break IPv4 on the way - https://datatracker.ietf.org/doc/html/rfc5220#section-2.2.2

https://en.wikipedia.org/wiki/Unique_local_address

"...ULAs are somewhat analogous to IPv4 private network addressing,"

 

"...but with significant differences."

Stupid ISP
Misleading ipv4 habits
