>Description:
	Sep 13 20:40:23 capsicum /netbsd: arplookup: unable to enter address for 24.1.64.34 (host is not on local network)

	note, that address *is* on the local network.  the network mask is /20.

	de0: flags=8963<UP,BROADCAST,NOTRAILERS,RUNNING,PROMISC,SIMPLEX,MULTICAST> mtu 1500
	media: Ethernet autoselect (10baseT)
	status: active
	inet 24.1.65.208 netmask 0xfffff000 broadcast 24.1.79.255
	inet6 fe80:1::280:c8ff:fef8:71bc prefixlen 64

>How-To-Repeat:

	configure a machine as above.  Try to connect to a host on a
	different /24 but on the same /20.

>Fix:
	Unknown.  Will update this pr if I figure out how things work.
