What is the best way to perform a MAC-IP address resolution?

What do you mean exactly?

IP addresses are resolve to MAC addresses by
using ARP.

Any book that explains ARP and RARP on the same
page(s) without explaining that they are NOT practically
related to each other is a worthless piece of [junk].

Use it for a doorstop.

RARP are ARP are alike in two ways only: They use a
very similiar packet type and they rhyme.
 
What I am trying to get at is that in Netmon in shows me the MAC addresses
but not the ip addresses. How do I take the MAC address and resolute that
to an IP address? I got around this by looking in my Cisco Router arp
table, but is there not a way to do this with some type of command?

Thanks.

Some protocols DO show the IP addresses but for other
protocols this doesn't make sense (they aren't IP based)
or shows them only in the 'data' portion -- look at the
detail for the ARP or the far columns for DHCP etc.

[I have/had to be careful since the SMS(full) version
of NetMon does more than the included Server version,
but I think you will find this works and is limited to the
free version...I did go and check one of my Servers that
does NOT have the SMS version.]

In Data Capture --> Display --> Addresses there is provision
for adding an address, and setting the names you wish to see.

(You can also make it permanent, and save the whole configuration.)

Doesn't stop you from having to look them up (save them in an
Excel spreadsheet or text file if you take the trouble) but it gives
you a way to configure to use those names etc.
