Re: [v6ops] reclassify 464XLAT as standard instead of info - double stack coexistence

[JORDI PALET MARTINEZ <[e-mail]>]

Are you going to pay from your pocket the operators for the extra CGN cost? They may agree in that case!

    False, they always have access to NAT space.
    
    Keep NAT for IPv4, leave IPv6 alone.

    That need can not be satisfied to a large scale.  Make it work inside 
    some domain, with some translation, but cant work for all.
    
    It's plain NAT.

    I agree.
