- Tamper proof casing
- Guaranteed one way transmission
- No physical return path
Technical Notes
Configuring ARP for use across Data Diodes
Address Resolution Protocol (ARP) is a protocol used to ascertain the hardware address or Media Access Control (MAC) address from an IP address. Typically a sending station knows the destination IP that they wish to send to but does not the MAC address. Before communication between the 2 hosts can occur an ARP request is sent to discover the destination MAC address. The ARP request is directed to the destination IP address using a MAC broadcast address FF:FF:FF:FF:FF:FF. All devices on the subnet receive this broadcast but only the destination with the correct IP address will respond.
