[Dnsmasq-discuss] DHCP tag being ignored?

[Dave Thompson]

Thank you for your response! Got me thinking about releasing the IP address from the Windows machine; in the end, I found instructions here: https://superuser.com/questions/470585/how-to-force-windows-7-to-ask-for-a-fresh-ip-address-from-dhcp-server on how to force Windows not to request an IP address from the DHCP server (Dnsmasq honours that).

In particular:


ipconfig /release
net stop dhcp
net start dhcp
ipconfig /renew

This worked!

Thank you all,

Dave

i think you have to release the address, first... something so that the VM won't
try to request the last address it had... if it requests a valid address that is
not in current use, it will be allowed and accepted IIUC...

in the past we've renumbered the network addresses so the old numbers were not
valid which forced the assignment of a new address which was the desired
effect... when we renumbered the addresses, we basically just changed the 3rd
octet...

eg: 192.168.0.*/24 -> 192.168.100.*/24

maybe you can do something similar to reach your desired objective?
