DNS resolver resolves LAN IPs

[Peter Skvarka <ps%softinengines.com@localhost>]

Hello,

Has anybody similar problem or what is set incorrectly ?

I have fresh installation NetBSD 10.1, with static LAN IPv4 address and 
defaultroute.
Problem is that OS first tries to resolve LAN IP to DNS even when I try 
to ping to IP target.
When I try ping to LAN neighbor (for example gateway 192.168.1.1) then 
it tries first to resolve 192.168.1.1 to DNS name (query PTR 
1.1.168.192.in-addr-arpa which fails after approx.15 seconds) and then 
starts pinging and receives replies.
When I stop ping and start again the result is the same also the same 
when trying to ping behind router.
When I comment DNS server in resolv.conf then ping starts quickly, all 
is ok.
On machine I have another two network cards and behavior is the same. I 
have not this problem with another NetBSD 10.1 installation on notebook.
