Which application/process sends arp requests?

Question

linux

Hello.
Arp requests are constantly transmitted between the router and the computer/devices.
Example:

6902	2022-03-13 14:19:50,073255	MotionCo_77:*:*	Broadcast	ARP	60	Who has 10.1.1.10? Tell 10.1.1.7
6903	2022-03-13 14:19:50,073341	1e:5d:4e:2a:*:*	MotionCo_77:*:*	ARP	42	10.1.1.10 is at 1e:5d:4e:2a:*:*

The question arose: if the router sent a request to me, the computer, then which process will respond to it?

Answer 1

The OS network subsystem will respond to incoming ARP requests. If you have wi-fi network adapters, it is better to remove the poppy address from the question.
