Systems will tend to get the same IP address from the DHCP server. This is because of a couple of things. The first is that if they connect again before the original lease has expired, or if the system requests the the same IP address and it is not assigned, it will normally get it. A side affect of this is that if you configure a fixed IP address after a system has a DHCP lease with a different IP address, it will keep the one it has. You have to wait for the lease to expire, or release the current one and ask for a new one. (dhclient -r eth0) You may want to add the system names/ip addresses to your hosts file on the different systems, so you can connect by name, instead of IP address. For Linux, it is /etc/hosts. The MAC probably uses the same file. For Windows, it depends on the version... Here are a few on mine. printserver is an Ethernet print server, and brother is a Brother MFC-7820N networked all in one machine. 192.168.1.34 mary.infinity-ltd.com mary 192.168.1.100 printserver.infinity-ltd.com printserver 192.168.1.101 brother.infinity-ltd.com brother As a side note, you can add "DHCPRELEASE=yes" to the ifcfg-<interface> file to have the DHCP lease released when the interface is brought down. This can be handy for laptops that connect to more then one network, especially if the lease time is longer then the time it takes to go from one network to another.
