This is a stealth approach and won’t be noticed immediately by the network. As far as its impact is concerned, it’s not that much damaging and its scope is limited. In the second approach, hackers disperse an unsought message that is commonly known as “gratuitous ARP”. This is an ...
Gratuitous ARP allows a device to send an ARP Request packet that carries its own IP address as the destination IP address. Gratuitous ARP has the following functions: Checks for IP address conflicts. When the protocol status of a device interface changes to Up, the device broadcasts gratuitous...
By default, the device sends a gratuitous ARP message every 60 seconds after this function is enabled. You can set the interval by using the arp gratuitous-arp send interval command. If the device has been enabled to send gratuitous ARP messages, go to Step 4. Run the display arp an...
After a VM is migrated from one gateway to another, the new gateway learns the ARP entry of the VM (generally from the gratuitous ARP packets sent by the VM) and generates host information (including the host IP and MAC addresses, L2VNI, and gateway's VTEP IP address). The new gateway...
It tricks your interested hosts (and the switch) that your machine MAC address now owns the IP of the old IP gateway by sending out a "gratuitous arp". The interesting machines will unwittingly send all gateway/default route destined traffic to your machine. Your machine will now forwa...

I am running the "https://github.com/espressif/esp-idf/tree/master/examples/protocols/https_request" on ESP32-DevKitC. It seems that the ESP32 is taking a really long time to retrieve the DHCP IP. For applications where only 1 packet nee...
