Ip >> MAC Address?

a MAC level ethernet transmission?
How do i get a MAC address from an IP on my network?
I'll remove the post when answered?

thanks a lot guys/gals- i'd appreciate it :-)

there are a couple of different programs that let you do it. A quick search on google brought up this.....http://www.youngzsoft.net/cc-get-mac-address.htm

I use Agilent Advisor, not free but gives you all kinds of information about a local network.

I think this is what you are looking for. Why are you going to remove the thread?

Hmmm...
helpful!

Another way would be to use a packet sniffer, and try todo a whois or ping to the target ip/hostname. In the output that the packet sniffer gives you, you can request information from the target such as the mac adress.

Cheers.

simply ping the ip address and then check the arp entries to get its mac!

if the machine is on a different subnet you will get the MAC of the router.

ping x.x.x.x
then use arp -a to see the arp entries

arp/?
ARP -s inet_addr eth_adr [if_addr]
ARP -d inet_addr [if_addr]
ARP -a [inet_addr] [-N if_addr]

-a Displays current ARP entries by interrogating the current protocol data. If inet_addr is specified, the IP and Physical addresses for only the specified computer are displayed. If more than one network interface uses ARP, entries for each ARP table are displayed.
-g Same as -a
inet_addr Specifies an internet address.
-N if addr Displays the ARP entries for the network interface specified by if_addr.
-d Deletes the host specified by inet_addr.
-s Adds the host and associates the Internet address inet_addr with the Physical address eth_addr. The Physical address is given as 6 hexadecimal bytes seperated by hyphens. The entry is permanent.
eth_addr Specifies a physical address
if_addr If present, this specifies the Internet address of the interface whose address translation table should be modified. If not present, the first applicable interface will be used

thank you all for answering my question... whie black_death had the answer i was looking for- thank you ;-)

NBTSTAT works too, again- thanx y'all

-take it easy :-)

I think the NBTSTAT command will accomplish the same thing too.
NBT is short for NetBIOS over TCP/IP, so you will need to have that enabled for it to work.(having it enabled is not good, unless you are behind a good firewall)

Just use nbtstat -a [ip_addr]

This is a good info page.

Im with algaen......

I was under the impression that if the ip is on your own network NBTSTAT will get the MAC address

Well another way would be telneting into the router, the ip in question is behind, running a SHOW ARP ***.***.***.*** at the console.
