Assuming you IP adresses are in Column A100 and names in Column B100 then
Vlookup will return a name from an IP address thus:

=vlookup(cell address of IP address you are looking for,a1:b100,2,false)

I am working with a report that provides a list of several IP addresses for
employees accessing my training site. I have a list of the names that match
each IP address. I would like to be able to run a report/macro where the IP
addresses change to an actual name for data analysis. Is there a way in
Excel 2000 to perform this type of function? Thanks for any help you can
provide.
