Default Questions

Hi I am new to this site, and I'm seeking some help on a few Networking questions.

1. First, I need to find all the machines in my local area segment, what is the command for this?

2. How do I add/remove a machine from my ARP tables?

3.How do I find the ARP address and how many bytes it has?

4. Is there a way to determine the manufacturer of a NIC card in a machine in my segment? In what way could I possibly do this?

5. How do I figure out who manufacturers a MAC address?

Thanks for any help anyone can give me, I realize I have some abstract questions, I'm doing a lab and having trouble with these aspects. Thanks again for any help.

in a DOS window:

net view will show you all machines on a LAN.

ipconfig /all will show you information about your NIC's and adapters. the first 6 digits of the MAC address are the manufacturer, i think.
check here for that http://www.coffer.com/mac_find/

about ARP, i don't know much. a little tool called Ethereal is very useful in network analysis... needs to be installed along with WinPCap.

Is there a member here that knows anything about ARP Tables?
