how to find ip address from mac address?
It happened more than once.
At a customer's office, there is a device with an unknown ip address.
We know its mac address.
The ip address might be different from the network.
For example, the customer's network might be 10.1.0.0/16, whereas that
device might have the ip address 192.168.200.123/24.
For example, it might be a managed switch that has kept its default ip
address. So, it works as a switch, but I cannot manage it.
Apart from a sniffer, is there a (free?) software that can scan the network
and find ip addresses of all hosts, and/or only of those whose mac address ...IP Address allocation by mac address
Is it possible to give a specific mac address a fixed IP address when

Yes. Just create an ip-address-object with manual assignment type in
the DNS/DHCP management console. Enter the mac-address, unload and
reload the dhcpsrvr module and release and renew the address at the

My goal is to discover the IP address of the LAN interface of a Cisco
1721 router (it's located at the office where I work).
I know the MAC address because it's written in a sticker at the bottom of
the router. But I don't know the password to the router admin console :(
The router's LAN interface is connected to a Sun workstation that has two
NICs (one of them connected to the cisco and the other connected to a 24-
port switch). The Sun machine works as a...IP address vs MAC address
Ok somebody explain this to me. I understand how IP addresses are
issued(well sort of...lol) Is it one IP address to one MAC address?(not
accounting for non routable IP space) I understand there can only be one
WAN facing IP address per machine/MAC/NIC/etc realizing multiple NICs
possible on one computer. If that is the case then how can say a Comcast
DHCP server keep from issuing an IP to a MAC address that another provider
has already issued an IP for? In this case perhaps someone has made up a
MAC address to use in their router for cloning purposes. Or does it really ...Virtual IP Address (Mac Addressing)
We are planning a 26node cluster Groupwise implementation early next
year. After meeting with our Network people, one of them posed the
question if Server A (connected to Switch A) fails over to Server B which
is connected to Switch B (Will the virtual mac IP address that fails over
to Server B be recorded correctly). I was under the impression that the
application layer managed it, but we need clarification for Netware.

Well, the MAC address would really be tough as NDPS/iPrint has no need
for the MAC address and as such does not record that information
anywhere. If the pritner i...How to get MAC address & IP address?

Hi all. For the life of me, I can't remember what the name of the software

setting a static ARP listing for a MAC address on my computer with an unused
IP address, but that didn't work. Help?

We are using NetWare 6.5 DHCP in our environment.
I would like to assign IP addresses to PCs based on the particular
manufacturer ID in the MAC address, can this be done?
I tried but the DNS/DHCP management console wouldn't accept the wildcard
character in the MAC addresses field. Is there any way to workaround it?
Will import accepts wildcard MAC?
AFAIK, th DHCP protocol does not support what you want, in any
implementation, as it is not part of the DHCP standards.

AFAIK this isn�t possible. You have to add two different manual
