Re: Choosing length of lease

[Mike Carney - SunSoft Internet Engineering <[e-mail]>]

Hi John,
	Typically, we use (and we tell customers) the lease which meets the following
criteria:

	1) Long enough so that if the underlying hardware, etc upon which the DHCP
	   service runs goes on the blink, the hardware, etc will be fixed before
	   leases start expiring.

	2) Given #1, the shortest possible lease which meets this requirement, so
	   that any changes to DHCP parameters are picked up on a timely basis (such
	   as renumbering networks, new services) and expired IP addresses are
	   recycled rapidly (they are in short supply).

	The typical answer runs from 6hours (Sun's internal) to 2 days (for a certain
	customer). Both numbers arrived at using #1 and #2.
