[Randy Bush]

in /etc/rc.conf, i have

ifconfig_em0="inet 147.28.0.60 netmask 255.255.255.0 <media stuff>"
ifconfig_em0_alias0="inet 192.83.230.1 netmask 255.255.255.255"
ifconfig_em0_alias1="inet 198.133.206.1 netmask 255.255.255.255"

and i constantly log

Jan 11 00:30:44 bbgp /kernel: arplookup 192.83.230.253 failed: host is not on local network
Jan 11 00:39:16 bbgp /kernel: arplookup 198.133.206.253 failed: host is not on local network

Jan 11 01:42:15 bbgp /kernel: arplookup 192.83.230.253 failed: host is not on local network

yet i can
