Learning and testing

Satoshi T Thank you @marek . YAMAHA has acquired communication control technology through the development of electronic musical instruments and MIDI. Japanese small companies use YAMAHA routers for their internet connection.

marek Thank you @Satoshi.
Is the configuration complicated?

Satoshi T Setting command system of router is clear. However, it is difficult to find a setting to create some subnets and automatically set the address using SLAAC and RA in an environment where only /64 range of prefix which routed from my itnternet provider. IPv6 has so wide address range🤗, but the freedom of subnetting is limited than IPv4🤨. Now I'm trying💪🏻.

marek ... keep trying ;)
I also heard about dhcpv6, but didn't tested it yet.
Now, I need to read about SLAAC, too ;)
