arplookup: unable to enter address - host is not on local network

[Benjamin Lorenz <bl%pocketservices.de@localhost>]

Talking about http://ftp.netbsd.org/pub/NetBSD/NetBSD-current/src/sys/netinet/if_arp.c: I have a hoster (www.vultr.com) with some strange(?) network setup. All kernels (6.1 and 7.0 RC) complain with plenty of log messages highlighted below. They screw up dmesg output so I had to comment out the log statement and compile my own kernel.

Question: Is this setup something vultr should change, or is our debug logging a little bit too pedantic/paranoid so we should consider removing it?

Thanks for insight,

Benjamin
