I am working in a serviced office, where I do not control the DHCP server.
I have more than 3 machines that I need to have the same IP address after they get assigned. How would it be possible for me to "reserve" a few IP address to my own machines?
Let's suppose I boot up VM A and it sends out a DHCP REQ. I get IP abcd assigned to it.
Now I boot up VM B and it receives IP efgh. After I shut these VMs down (longer than the DHCP refresh interval, eg, several weeks), and restart them, in the normal/usual case, they get assigned different IP addresses.
I need "fixed" DHCP IP addresses due to the nature of my applications. In other words, assuming VM A is assigned IP abcd, and VM B, IP efgh. After they're shut down, their IP addresses goes away (assuming the VMs are not restarted within the DHCP refresh interval). What I'm looking for is a DHCP client application that can send out DHCP REQ for VM A with VM A's MAC address, and DHCP REQ for VM B with VM B's Mac address, on my other machine's that are up and running.
Is there any DHCP client program (on Mac OS X, or Windows) that can reserve/renew addresses on behalf of my (shutdown) VMs (on my other up and running machines)?
