Why ARP need ARP cross LAN request?
When I am reading a document:
You see the host A(
10.1.0.1/8) send ARP Request for
220.127.116.11/8's MAC address.
In general, the ARP request is for MAC address in the same LAN. why there need the cross LAN's ARP request? further on will need the ARP proxy. because I think the host A send to host B data, it can through the Router Forwarding.
What's the 10.1.0.1/8 tries to ARP 18.104.22.168's benefits?
