Address Resolution Protocol

ARP - (Address Resolution Protocol) je TCP/IP protokol koji se koristi da pretvori IP adresu u fizičku adresu, tzv. DLC (Data Link Control) adresu, kao što je Ethernet adresa. Host (čvor) u mreži koji želi dobiti neku fizičku adresu emituje (broadcast) ARP zahtjev (request) u TCP/IP mrežu. Čvor na mreži koji ima adresu iz zahtjeva, u odgovoru šalje svoju fizičku (hardver) adresu.

ARP je protokol koji IP protokol koristi da bi utvrdio odnos izmedu IP mrežnih adresa i fizičkih adresa koje koristi DLL protokol. Gledajuci OSI-ISO strukturu, ARP funkcionira nešto ispod trećeg sloja i obično se koristi u Ethernet mrežama.[1][2]

Radni opseg

ARP spoofing: Uspješan "ARP spoofing" napad dozvoljava napadaču da izvrši "a man-in-the-middle" napad.

Protokol za razrješavanje adresa (ADP) je protokol koji sesastoji od zahtjeva i odgovora. Njegove poruke direktno su obrađene protokolom sloja veze. Prenosi se unutar granica jedne podmreže i nikada se ne usmjerava.[2]
