T2   Advanced Topics in DNS and BIND 
Paul Vixie, Internet Software Consortium

Who should attend: Name server administrators and software developers who need a deeper understanding of the DNS protocol and of the internals of BIND. Participants should already be responsible for the operation of at least one name server, should be familiar with Internet protocols such as TCP and UDP, and should be able to recognize C source code when they see it.

This tutorial will survey the DNS protocol and describe upcoming extensions to it, as well as implementation considerations in BIND. Topics will include:

	DNS message format
	DNS resource record format
	Zone file format, and zone transfers
	Incremental zone transfer
	Dynamic update and deferred update
	Real time change notification
	DHCP interaction
	BIND current status
	DNS security
	DNS politics
	BIND Version 8

After completing this tutorial, participants will know what the IETF has been up to lately, and what to expect in upcoming BIND releases. For attendees who have taken Paul's tutorials in the past, this tutorial will not be a rehash of prior material - new subjects will be covered.
