Comments on: What layer of the TCP/IP would ARP and RARP belong to http://itknowledgeexchange.techtarget.com/itanswers/what-layer-of-the-tcpip-would-arp-and-rarp-belong-to/ Thu, 26 Nov 2009 14:01:15 +0000 http://wordpress.org/?v=2.6.2 By: BlankReg http://itknowledgeexchange.techtarget.com/itanswers/what-layer-of-the-tcpip-would-arp-and-rarp-belong-to/#comment-66299 BlankReg Thu, 30 Jul 2009 22:46:19 +0000 #comment-66299 ARP is layer 3 - no doubt. It is an IP function, so is network layer. I would also like to make the point that ARP does not translate IP to MAC, it is the method that is used to get the MAC address for a particular IP address. Not a translation, just finding out where a particular IP address lives. Just like me asking you what your house number is, I still address the letter to you, but add the house address where you live. ARP is layer 3 - no doubt. It is an IP function, so is network layer.
