[ipv6-wg] Belgian limits on CGN/NAT?

Hi Marco,

I think this is quite logic. An IP address with less ports that what RFCs specify, is not IP. It breaks lots of thinks and as many users you have sharing the same address, worst.

I’m aware of other governments/regulators working in the same direction, even allowing only CGN with a maximum lifetime (about two years) and only if you are at the same time deploying IPv6.

Regards,
Jordi

    Dear Colleagues,
    
    Unfortunately so far I have only found Dutch (and French) sources, we would be happy to receive pointers to English texts on this.
    
    The Belgian Institute for Post and Telecom (BIPT) recently ran a consultation to evaluate the National IPv6 Workplan, which was released back in 2012. The deadline to comment had already passed, but I trust our Belgian community members to have found this via other sources in time to respond.
    
    http://www.bipt.be/public/files/nl/22027/Raadpleging_ipv6.pdf
    
    In this, there is one question in particular that caught our eye, number 6, which roughly translates to a question asking if the requirements in a Code of Conduct on the usage of CGN which was agreed in 2012 are still current and workable and whether or not this CoC should be reviewed.
    
    Further in the introduction of the consultation, chapter 1 (page 3), there is some more information on this agreement:
    
    > Om de eindgebruiker toch eenduidig te kunnen identificeren was er beslist om bijvoorbeeld het delen van een IP-adres te beperken tot maximaal 16 gebruikers en dit via een gedragscode die door de sector werd ondertekend.
    
    Translation by me:
    
    > To identify users, it was agreed that sharing a single IP address would be limited to a maximum of 16 users and that this limit would be part of a code of conduct which would be signed by the industry” 
    
    So far we have not yet been able to retrieve a copy of this Code of Conduct or a list of participating operators and would be happy to receive more information. But as the text suggests that there is an agreement between Belgian network operators and the government that would limit the use of CGN to 16 users per address. We wonder then, if this is the “magic ingredient” of why the IPv6 roll out in Belgium is so successful.
    
    As a question to this Working Group, would a 16:1 ratio be realistic and workable from an operational perspective? And further of course, do you think this form of cooperation between the public and private sector as a way to expedite the deployment of IPv6?
    
    Regards,
