Why ue0 do ARP on non local address when using static route?

man page says that ethernet-address (MAC) + fully-qualified-host-name (FQHN).
The issue is that host cannot resolve the address by using FQHN, thus no ARP any
more, but no traffic either.
After adding FQDH in the /etc/hosts file then, ARP request uses FQHN instead of
The question is why ARP occurs?
The subnet (10.227.148.0) is not matching with the local network/netmask
(10.234.37.0/24) unless somewhere in the system is using default 255.0.0.0
netmask for 10.0 A class network by mistake.

I'm not sure what "QFHN" is, but setting up an entry in /etc/ethers provides the
IP to MAC address mapping that ARP attempts to provide dynamically.

Assuming there's a router at 10.234.37.1 which knows how to get to
