Introduction RARP stands for “Reverse Address Resolution Protocol”. RARP is now considered as an old protocol because of use of IPv4 and we use it very less anymore to assign IP addresses to hosts. Now, it has been replaced by BOOTP and later by DHCP. Reverse ARP differs from the Inverse Read more…

Multicasting is a technique used in network communication to deliver packets from a sender to multiple recipients simultaneously.  Definition IGMP is a communications protocol used by IP network hosts Read more…

Introduction ARP stands for “Address Resolution Protocol”. Definition ARP is a request-response communication protocol used to associate(map or translate) the IP network address to the Hardware or Physical or Media Access Control(MAC) address. In another words, ARP is a type of resolution protocol used to dynamically map layer-3 network IP addresses Read more…
