And how is making the protocol historic going to affect broken stuff that's already been deployed (which is what is causing those observed problems) - or, to put it more precisely, how is changing the protocol's label going to have _more_ effect (i.e. above and beyond) than putting out a document which says 'here are some problems with using this, don't use this unless you know what you're doing'? > I believe there is data to show this time is different (iana and apnic > are exhausted, successful v6day, docsis 3.0 and LTE deployment ... I am personally dubious, since although technically we're now formally out of space, I suspect we're just going to transition from a period in which it was somewhat difficult to get IPv4 space [convincing an RIR you needed it] to more difficult [acquiring space from a current holder] - that is, for those organizations which don't already have space stockpiled. And that, along with somewhat greater use of NAT - which has, of course, been keeping the Internet functional for well over a decade) - will be the approach the market prefers. We'll see, though, won't we? Noel _______________________________________________ Ietf mailing list Ietf@xxxxxxxx https://www.ietf.org/mailman/listinfo/ietf
