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

[Benjamin Lorenz]

Talking about 
http://ftp.netbsd.org/pub/NetBSD/NetBSD-current/src/sys/netinet/if_arp.c: 
<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
