Security Basics: RE: How to find a changing IP on ethernet network

[Bénoni MARTIN <Benoni.MARTIN () libertis ga>]

Hi,

The person should also be warned on his(her) screen about the IP address trouble, but according to your statements, it 
does not seem to bother her:(.

The way I would deal with this trouble is tracking down the MAC address and/or name of the computer, and then try to 
find the computer with that.

But it will depend on many things: DHCP or not? How many computers do you have connected to the hub? Do you have an 
up-to-date list of the MAC addresses, ...?

Objet : How to find a changing IP on ethernet network

Hello. I have a client with a simple Ethernet network with HUB's 
connecting and there is one person that is changing it's IP and creating 
conflicts. What would you do to track down that person? i mean, to find 
who does that?
Thanks!
Ivan Hernandez
