What else can I help you with?
If a device does not know its own IP address can it still use ARP?
No - in order to use ARP it would have to send a broadcast for information with a return address of itself. Since it doesn't have an IP address it cannot do that. Furthermore, without an IP address it couldn't participate on the network.
What does IP use to find the MAC address for a given IP address on the local sudnet?
ARP
What is the use of reverse ARP?
Reverse ARP is used to Obtain IP address from a Server(responsible for IP addresses allocation) by providing its layer 2 (MAC) address.
What mechanism does ARP use to resolve IP addresses?
ARP is a Third layer or Network layer protocol. ARP is an address resolution protocol . The mechanism used by ARP to resolve IP address is look up table.
Differences between arp packet transmission and ip packet transmission?
an arp (address resolution protocol) comes into picture when we have the ip address of our destination but we dont know the mac address of our destination.Normally when we open a web site this is the process which takes place.IP packet transmission comes after arp when the destination mac address is obtained after arp request.so an ip packet contains both source & destination IP & mac addr.
What end-system command would you use to delete a specific entry from an ARP table?
arp -d ip-address
What is arp operation?
ARP is used to find a MAC (layer-2) address, if you know the IP (layer-3) address.First, a device will search its ARP cache, to see whether it already happens to have the required address. If it doesn't find the address, it will send an ARP request as a broadcast, which basically asks "Who has such-and-such an IP address?" The machine that has the requested IP address will send an ARP reply.
Diskless system uses which protocol arp or rarp?
You have to use both. ARP and RARP cannot be used for the same purpose one gives IP from the MAC address another one MAC address from IP.
What is the protocol that is used to discover a physical address from a known logical address and what message type does it use?
The protocol used to discover a physical address from a known logical address is the Address Resolution Protocol (ARP). ARP operates by broadcasting an ARP request message on the local network, which contains the known logical address (IP address) and asks for the corresponding physical address (MAC address). The device that owns the requested IP address responds with an ARP reply message, providing its physical address. This process enables devices on the same local network to communicate effectively.
Which service does arp provide?
It resolves an IP address to a MAC address.
What type of header does an ARP frame contain?
ARP and RARP protocols are present at network layer. ARP is short form of address resolution protocol. IP is the type of header an ARP frame contain .
Which protocol is used to convert logical IP addresses to physical MAC addresses?
Address Resolution Protocol (ARP)ARP is primarily used to translate IP Addresses to Ethernet MAC Addresses.
