[ipv6-wg] Disband IPv6 WG

Beside the part of sending SMTP email over IPv6...

Jens, what did you drink this lunch time? It seems to be good :-)

I take your email as a good joke: see the amount of replies !

    Hi,
    
    after now almost 12 years using, working and teaching[1]
    IPv6 I've come to the conclusion that IPv6 is a mistake and will
    not work.
    
    Therefore the RIPE IPv6 WG should be disbanded and replaced
    with a new WG that MUST investigate all possible solutions to
    artificially prolong the live of IPv4 till the day a new successor
    for IPv4 is created and implemented!
    
    Some great ideas[2] are already proposed, some of them already
    implemented:
    
    - Use of NAT
    - Use of the first Class-A network 0.0.0.0[3]
    - Use of parts of localhost Class-A network 127.0.0.0
    - Use of (parts) of Class-D address space (multicast)
    - Use of Class-E address space (future use)
    - Using part of the UDP / TCP port range as extension for the
      address.
    
    Some of the reserved address spaces could also be used. E.g. nobody
    is using 192.0.2.0/24 for documentation anyway.
    
    It should also be investigated to take back legacy IPv4 resources,
    although the "owners" of these resources might already selling
    them on the open market.
    
    It MUST also be considered not filtering on Class-C[4] bounderies
    but going for something smaller like /26 or /27 in the global routing
    table. Also new Class Designations for these prefixes MUST be created.
    
    The new successor to IPv4 should not make the same mistakes as IPv6.
    
    - IT MUST have NAT
    - It MUST have Classes
    - IT MUST have DHCP
    - It MUST have ARP
    - It should be possible to drop ICMP the same impact as in IPv4. Many
      experts I talked to over the years told me that blocking ICMP has
      no negative impacts.
    - It MUST only have numbers and dots "."
    - There should be absolutly no reasons to use "[ ]" in URLs
    
    Probably the best way to proceed is to just add one or two octets to the
    address.
    
    One of the reasons for the above is that there are so is so many good
    documentation already written about IPv4! And people already know about
    IPv4! Why waste this knowledge and experience? There is also plenty of
    good software out there that can't work with IPv6[5] Change is bad!
    People don't want to learn!
    
    IPv4! MUST! NOT! DIE!

    [1] at least trying to teach, as one can see from the great number of
        people actually using IPv6 with little success
    
    [2] https://netdevconf.info/0x13/session.html?talk-ipv4-unicast-expansions
    
    [3] https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=96125bf9985a
    
    [4] a Class-C network is the equivalent of an /24. I was told by experts
        that the definition of some bit set in the first octet of an IPv4
        address is complete and utter nonsense
    
    [5] like a 20 year old shell script that is so important for $university
        that it would be hard for them to implement IPv6!
