System: NetBSD birch 1.5 NetBSD 1.5 (BIRCH) #0: Thu Jan  4 19:03:40 CST 2001     scottr@birch:/usr/src/sys/arch/i386/compile/BIRCH i386

>Description:
	The DHCP server (version 3.0b2pl9) included with NetBSD 1.5 does
	not support dynamic DNS well.  In particular, some clients
	(particularly NetBSD running dhclient) can have great difficulty
	acquiring a lease.

>How-To-Repeat:
	Configure named and dhcpd for dynamic DNS updates.  (Using the
	one-lease-per-client option may make the problem easier to
	reproduce.)  Watch the dhcp server's debug output using `dhcpd -d'
	and note many lines stating something to the effect of:

	/usr/src/usr.sbin/dhcp/common/dns.c(426): non-null pointer

>Fix:
	Apparently, updating to any version 3.0b2pl11 or later will resolve
	the problem.  I am successfully using 3.0b2pl16 on this system.
