Find machine name from IP address

did this on Windows XP

start with IP - can do tracert <ip_address>, sometimes this will give it to you. but other times, it will just give you the DHCP-given IPname, which doesn't help.

arp -a gives you a table of IP addresses to MAC addresses

nbtstat -A <ip_address>

Example output and explanation:

       NetBIOS Remote Machine Name Table



   Name               Type         Status

---------------------------------------------

MIKE           <00>  UNIQUE      Registered

MUSHROOM       <00>  GROUP       Registered

MIKE           <03>  UNIQUE      Registered

MIKE           <20>  UNIQUE      Registered

MUSHROOM       <1E>  GROUP       Registered



MAC Address = 00-4F-49-05-8D-56

--------------------------------------------



Group names represent Workgroups and Domains

00 is the Workgroup

1E means that the machine is a potential master browser.



Unique names represent individual machines/users (and are unique)

03 is the Username 

00 is the Computername as a client

20 is the Computername as a server 

(Not only do computers have more than 640k, but they're both clients

and servers now too!!)



All this, and you get the MAC address too.
