What are the differences between ARP and DNS?

DNS is used to map domain names to IP addresses plus a bunch of related things. DNS is a layer 7 thing. ARP is a layer 2 thing. DNS queries traverse the whole internet.

What are the differences between ARP and RARP?

In Address Resolution Protocol (ARP), Receiver’s MAC address is fetched. Through ARP, (32-bit) IP address mapped into (48-bit) MAC address. Whereas, In Reverse Address Resolution Protocol (RARP), IP address is fetched through server. Through RARP, (48-bit) MAC address of 48 bits mapped into (32-bit) IP address.

What is difference between ARP and Garp?

Gratuitous Address Resolution Protocol (GARP) requests provide duplicate IP address detection. A GARP request is a broadcast request for a router’s own IP address. On the other hand, ARP dynamically binds the IP address (the logical address) to the correct MAC address.

  • Proxy ARP.
  • Reverse ARP (RARP)
