Re: how IPv6 address and parameter configuration follows the KISS principle?
The problem is that IP6 was a bad design. It was later fudged (not relating MAC to an IP6). It was designed with no thought of backward compatibility.
Yes, ITU is probably wrong. So is IP6, we need an IP8, with security & privacy designed in.
My router & ISP both have IP6. I can't change over.
1: Privacy of LAN. 2: Security of LAN. 3: Many things I have don't do IP6. 4:Many sites don't do IP6, all IP6 sites I use do have IP4.
The Router essentially has no Firewall or NAT if using IP6.
