sorry for the broad cross-posting... While waiting for the 2q2000 inverse tree audit to finish, <http://www.isi.edu/~bmanning/in-addr-audit.html> I crunched some numbers on the previous two quarters data. This is only for servers in the in-addr.arpa tree that responded. Servers w/ modified replies to the version query are not included but they are less than a single percent. <http://www.isi.edu/~bmanning/in-addr-versions.html> (Shouts to you folks w/ back level code... tis better to upgrade than not. And hiding your version is no protection.) Comments appreciated. --bill
