  • @elpaisitadeoro well, this is kinda late to warn you, but PCs DO keep an ARP Cache/table, try the command "arp -a" and you'll see the table. Maybe if you are behind a router, the only line you are going to have is the IP and MAC from that router, because remember that ARP works in layer 2.

  • great!! XD

  • Thanks for the training vids. I used these as well as the CCNA manual I got from ciscoccnaforfree com and just passed yesterday.  Hope you all have as much luck as me.

  • You guys should really take it outside! WOW! Talk about ego.

  • If A is pinging B, A I think will send an ARP request to b, then b will send an ARP reply with it's ip address, and A will know how to get to B I think anyways........

  • type arp -a into ur command line and see

  • PCs do not keep any kind of ARP cache. It broadcasts ARP requests everytime it wants to establish a connection.

  • anyway it seems you know some stuff what is your problem with this?

    it says : CISCO CCNA MAC ARP TABLE

    it doesnt say : cisco ccna full internetworking explanation.

    it is just i suppose a part of a tutorial so other stuff will be explained elsewere.

    or do you think cisco cant explain networking decently?

  • if you just wanted to ping an IP and not a domain name , why you should send a dns request?

    this video cares about the NETWORKING part , not the application.

  • in a LAN enviroment Address Resolution Protocol is used to map OSI level 3 IP addreses to OSI level 2 MAC addreses. dont confuse it with dns , dns has to do with out of the lan connection .
