Re: [Dnsmasq-discuss] DHCP tag being ignored?
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!

Re: [Dnsmasq-discuss] DHCP tag being ignored?
Thank you for your help, but no luck I'm afraid. The Windows 7 VM is still being provided with a 192.168.0.104 IP address even though the MAC address is 08:00:27:ab:8b:7e. I can see that the Windows 7 VM is requesting 104. Perhaps Dnsmasq is honouring that and ignoring the config file? I will take a look at the code tomorrow; my C isn't great but I think perhaps the answer is in the way the tags are applied. Annoyingly, the log clearly shows that the tag 'vms' is being set by the 'dhcp-mac' config variable, so it's obviously being picked up! Any more thoughts!?

[Dnsmasq-discuss] DHCP tag being ignored?
Hi there, I am trying to configure Dnsmasq to provide a custom range of IP addresses for my VMs which will then map to a certain subdomain. The trouble is, the tag is being found (I can see in the log file) but the correct IP range is never provided. Here's my config file: domain=int.[redacted] domain=vm.int.[redacted],192.168.1.50,192.168.1.150 dhcp-range=192.168.0.50,192.168.0.150,12h dhcp-range=tag:vms,192.168.1.50,192.168.1.150,12h dhcp-mac=set:vms,08:00:27:*:*:* dhcp-host=98:E7:F4:BA:3D:AA,192.168.0.80 dhcp-leasefile=/var/lib/misc/dnsmasq.leases dhcp-authoritative log-dhcp >From the log: Apr 5 17:37:39 pi dnsmasq-dhcp[21541]: 3063663390 available DHCP range: 192.168.0.50 -- 192.168.0.150 Apr 5 17:37:39 pi dnsmasq-dhcp[21541]: 3063663390 vendor class: MSFT 5.0 Apr 5 17:37:39 pi dnsmasq-dhcp[21541]: 3063663390 client provides name: DWT-VPC-W7-0 Apr 5 17:37:39 pi dnsmasq-dhcp[21541]: 3063663390 DHCPINFORM(eth0) 192.168.0.104 08:00:27:ab:8b:7e Apr 5 17:37:39 pi dnsmasq-dhcp[21541]: 3063663390 tags: vms, eth0 Apr 5 17:37:39 pi dnsmasq-dhcp[21541]: 3063663390 DHCPACK(eth0) 192.168.0.104 08:00:27:ab:8b:7e DWT-VPC-W7-0 Can any of you point out what I am missing, please?
