The DNS slides I used to talk about DNS, TSIG, DNSSEC and reverse DNS can be found here: http://www.isc.org/misc/nznog/01-Introduction.ppt http://www.isc.org/misc/nznog/06-Reverse.ppt http://www.isc.org/misc/nznog/07-dnssec.ppt The cisco slides I occasionally referred to whilst waving my hands about BGP can be found here: ftp://ftp-eng.cisco.com/pfs/isp-workshops/studentcd-2003a/ Workshop_Materials The whiteboard scribblings and frequent rambling tangents were fortunately not recorded for posterity, but an air ticket and a nominal amount of beer can easily secure a repeat performance :) Joe
