Our DHCP is 10.0.0.2. But some computers get ip from 10.0.1.1 randomly and
they won't talk to others. I believe that we have one computer or router is
active as DHCP to assign ip to other computers. Using ARP -a I find the
computer or router MAC is 000393df7d32. How can I find the machine?

Hi Bob,

Surely you can see the IP address of this computer if you can see its MAC
address using arp -a, or am i missing the point?

cheers

AD,

Thank you for help.

We know that a machine with ip 10.0.1.1, subnet 255.255.255.0 and MAC
000393df7d32 is making the problem, but we can't find the machine. ping -a
10.0.1.1 doesn't give the host name. Our DNS and WINS don't have this
machine records because our network is 10.0.0.0 and 255.255.0.0 (they are in
the different subnet). I am assuming that some one has a laptop as DHCP with
ip 10.0.1.1 and subnet 255.255.255.0. Whenever the laptop connects to our
network, it messes up our system.

How can we find the machine's host name with MAC 000393df7d32?

Have you tried to telnet into 10.0.1.1 to see if it's a
router?

good point. I just tried it. all telnet 10.0.1.1, telnet 10.0.1.1 80, telnet
10.0.1.1 8000, and telnet 10.0.1.1 8080, returns "Could not open a
connection to 10.0.1.1"

any other suggestions?

Well, if it helps, the MAC address starting with 00-03-93 is identified as
an Apple device. So, I'd be looking for a Mac server or some other machine
running DHCP.

try using this:

nbtstat -A <ip address>

this should return the MAC on a Windows computer.

Nut,

Thanks for help. I tried it but got Host not found. I can png it but just
can't find the Host name. Any other suggestions?

In that case, it is not a windows machine.

Could be a printer, or other IP device.

How are you with Perl?

Todd,

Thanks for the help. We are focusing on all Mac machines now and we may be
close to find it. I will post back with the result.

By the way, I used to have a document lists first 6 # of MAC assigned to
manufacturers. Do you know which web site has this information?

Thank you again.

Nut,

I never use Perl. the first 6 # of MAC 000393 seems like Apple computer, I
am focusing on all our apple machines and will post back with the result.

Thanks.

bob

Finally, we found the 000393df7d32 is Apple Airport wireless router. Thanks
for all help.
