    so your not a fan of the smart edge and the stupid network.

I'm a fan of getting things right. A server somewhere 5 subnets away  
doesn't really know what routers are working on my subnet. It can take  
a guess and then wait for people to complain and then an admin to fix  
stuff if the guess is wrong, but I wouldn't call that a "smart edge".

Always learn information from the place where it's actually known.

        i'm ok w// that mindset.

        one should learn routing from the router(s),
        time from the time servers,
        DNS from the DNS servers,
        etc...

        now -normally- I would expect the router to focus on
        forwarding packets ... not be the time keeper, DNS server,
        handing out IP addresses,  hosting content for the HTTP protocol etc.

        sounds to me like your reacting to a particular style of 
        implementation (DHCP servers being multi-hops away) and want
        to move the function(s) closer to the edge, e.g. in the routers.

        and if we can get RA/ND -fixed- to accomodate all the functions that
        folks have grown to depend on over the years from a configuration service
        like DHCP - then we should be able to converge.  

        I am not a fan of the way DHCPv6 has developed/emerged.  And yes,
        I've re-written both client and server to fix the egergious problems 
        found in the current spec... (it now works just fine for doing things
        like handing out DNS servers for resolvers,  picking mapped addresses
        for my IVI service, etc.)   so my DHCP is non-interoperable w/ anyone
        elses.

        Thing is, its easier to fix DHCP code than to fix the router code.

        And the edge is not the LAN, its the device.
