MAC spoofing involves changing the Media Access Control (MAC) address of a network interface to impersonate another device on a local network. In contrast, ARP spoofing targets the Address Resolution Protocol (ARP) by sending false ARP messages, linking an attacker’s MAC address to the IP address of a legitimate device, which can lead to data interception or network disruption. While both techniques aim to deceive network protocols for malicious purposes, MAC spoofing focuses on the hardware address, whereas ARP spoofing manipulates the mapping between IP and MAC addresses.

What type of attack involves replacing a valid MAC address with an invalid MAC address on a local network?
ARP Spoofing
What are two potential network problems that can result from ARP operation?
Two potential network problems that can result from ARP (Address Resolution Protocol) operation are ARP spoofing and ARP cache poisoning. In ARP spoofing, an attacker sends false ARP messages to associate their MAC address with the IP address of another device, leading to man-in-the-middle attacks. ARP cache poisoning involves corrupting the ARP cache of a device by injecting incorrect mappings, which can disrupt network communication and redirect traffic maliciously. Both issues can compromise network security and integrity.
What is ARP Cache Poisoning?
Address Resolution Protocol (ARP) spoofing, also known as ARP poisoning or ARP Poison Routing (APR), is a technique used to attack an Ethernet http://wiki.answers.com/wiki/Ethernet or http://wiki.answers.com/wiki/Wireless_network. ARP Spoofing may allow an attacker to http://wiki.answers.com/wiki/Packet_sniffer http://wiki.answers.com/wiki/Data_frame on a http://wiki.answers.com/wiki/Local_area_network (LAN), modify the traffic, or stop the traffic altogether (known as a http://wiki.answers.com/wiki/Denial-of-service_attack). The attack can only be used on networks that actually make use of ARP and not another method of address resolution.
To make arp more efficient computers save recognized mac to ip address mappings on their hard disks in a database known as?
To make ARP more efficient computers save recognized mac to IP address mappings on their hard disks in a database known as ARP cache. ARP is an network layer protocol / third layer protocol. ARP provides mapping between Logical to physical address.
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.
Which type of address does arp resolve?
mac
What is the purpose of an arp request?
The purpose of an arp request is to map an IP address to a MAC address for the link layer to transmit a packet. For example, ARP will get a request to map 1.2.3.4 to a MAC address 12:fd:23:gf .Then ARP will cache the address mapping that next time an arp request doesnt need to happen
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.
What is ARP reply?
It's a response to a broadcast asking for the devices MAC ID. Routers and switches keep a table known as an ARP table which lists all the MAC ID's in the local area network. It will send ARP requests out to all the nodes in it's broadcast domain saying send me your MAC ID's. All the nodes in the network reply back with an ARP reply saying here is my MAC ID.
What does empty ARP cache indicate?
That the MAC addresses have expired
How do you obtain mac address of HP Laserjet P2055dn?
Usually you don't need the MAC address directly - except perhaps to improve the documentation in a large network.If you know a device's IP address, you can do a pingcommand; before and after, compare the ARP cache - the one that shows assignments of IP addresses to MAC addresses. In Windows, the steps would be more or less like this:Open a command window arp -d * (this will delete the ARP cache)arp -a (this will show the ARP cache)ping ... (this will connect to the IP address you specify)arp -a (show the ARP cache again. Compare with the previous one.)Usually you don't need the MAC address directly - except perhaps to improve the documentation in a large network.

Which service does arp provide?
It resolves an IP address to a MAC address.
