This is a side-effect of the ARP packet processing mechanism
described in STD-0037. All inbound ARP packet

An amusing trick to populate the ARP table is to ping the broadcast address.
Even if hosts do not reply to your ping packet (typically, Windows
machines), they are entered in the ARP table.
You still have to send a single packet, but it does all the work.

You've asked two different questions here, with differing answers:
1) How to do an arp resolution without sending traffic to the IP, and
2) Is it possible to do it all in one command.

The answer to 1) goes something like this: arp doesn't send traffic to
the IP.
Hi,
How could I perform a arp resolution without attempting to send traffic to
the IP address I am looking up ?
To rephrase my question, if I use arp(8), to obtain the mac address
associated with a specific IP address and that information is not yet in the
arp cache, arp(8) returns:
bash-2.03$
