By machine or by vendor? Every Linux, FreeBSD, NetBSD, Solaris, HPUX, MacOS, Windows box switches to TCP by default. General purpose computers usually support it. The nameservers shipped with these boxes also support TCP. The places which don't are some middle boxes which ends up breaking the connection between the general purpose computers and the recursive resolvers particularly in the home market. > - What kind of client are they?

Most of these general purpose computers also support EDNS though it is not enabled by default. > Feel free to provide any paper links you know. > > Regards, > > Daniel > > -- > Daniel Migault > Orange Labs -- Security > +33 6 70 72 69 58 -- Mark Andrews, ISC 1 Seymour St., Dundas Valley, NSW 2117, Australia PHONE: +61 2 9871 4742 INTERNET: [email protected] _______________________________________________ DNSOP mailing list [email protected] https://www.ietf.org/mailman/listinfo/dnsop
