CPE devices need to talk to something. If you take that something away you make the problem worse not better and don't say historic is not going to result in product support going away as no one believes that. The boxes on the carrier end of the 6to4 tunnels will need to be upgraded to deal with other issues and historic is likely to leave the operators in the unenviable position of having to run relays with known security flaws or kill the service. > >>> Brian > >>> _______________________________________________ > >>> Ietf mailing list > >>> Ietf@xxxxxxxx > >>> https://www.ietf.org/mailman/listinfo/ietf > >>> > >> > >> _______________________________________________ > >> Ietf mailing list > >> Ietf@xxxxxxxx > >> https://www.ietf.org/mailman/listinfo/ietf > > -- > > Mark Andrews, ISC > > 1 Seymour St., Dundas Valley, NSW 2117, Australia > > PHONE: +61 2 9871 4742 INTERNET: marka@xxxxxxx > > > -- Mark Andrews, ISC 1 Seymour St., Dundas Valley, NSW 2117, Australia PHONE: +61 2 9871 4742 INTERNET: marka@xxxxxxx _______________________________________________ Ietf mailing list Ietf@xxxxxxxx https://www.ietf.org/mailman/listinfo/ietf
