  Hi.

  I'm using 12-current and it shows names as follows.

% uname -a
FreeBSD carrot.ish.org 12.0-CURRENT FreeBSD 12.0-CURRENT #15 r334511: Sat Jun  2 13:26:19 JST 2018     ishizuka@carrot.ish.org:/usr/obj/usr/src/amd64.amd64/sys/GENERIC  amd64
% arp -a
sv3c.ish.org (xxx.xxx.xxx.xxx) at yy:yy:yy:yy:yy:yy on lagg0 permanent [ethernet]
carrot.ish.org (xxx.xxx.xxx.xxx) at yy:yy:yy:yy:yy:yy on lagg0 permanent [ethernet]
gw1.ish.org (xxx.xxx.xxx.xxx) at yy:yy:yy:yy:yy:yy on lagg0 expires in 1199 seconds [ethernet]
onion.ish.org (xxx.xxx.xxx.xxx) at yy:yy:yy:yy:yy:yy on lagg0 expires in 772 seconds [ethernet]

  I don't know why you cannot resolv names.

# I don't use /etc/hosts and use local_unbound to resolv names.
