networking - Is it possible to build an arp request packet in such a way that will cause a router to forward it over subnets? -

-

what i'm trying ip addresses in network, , thought, assuming know address of subnets use arp requests achieve if there way forward these requests on different subnets.

for example , assume had 2 hosts 192.168.0.2/24 , 192.168.1.2/24 connected via router using ip addresses 192.168.0.1/16 192.168.1.1/16. send arp request 192.168.0.2/16 192.168.1.2/16. thought maybe if arp request encapsulated in layer 3 header containing 192.168.1.2/24, or 192.168.1.255/24 dsetination work.

if possible , know tool happy know tool. if isn't, know happens packet 1 described above

i know happens packet 1 described above

if encapsulate info standard ip-packet, then, naturally, routed ip-destination host. yet if remote host knew nothing non-standard packet, nothing happen.

if want out of this, need have , running software server on remote host, able process requests. is, need proxy arp: either existing implementation, or made of own.

if don't have such "an agent" in target subnetwork, you're out of luck. go sequential ip-scanning until banned admin.
