	You put that so compactly that people may be confused.

	SIP uses URLs, sometimes truncate to "SIP addresses".

	ENUM is a system for advertisement and discovery of the
	URLs associated with a given phone number.  It uses the
	DNS as its database.

	NAPTR is the DNS record type used by ENUM for storing URLs.

	Current and recent versions of BIND support NAPTR records.

	Lots: RFC3761; Google "ENUM tutorial"; RIPE-46.

	I hope this helps.

	Best regards,
