DNSmasq DNS & DHCP: Devices assigned to Hosts list but still got other IP

[ohlalayeah]

I have installed OPNsense on my miniPC recently. The version should be 26.7.x.

The DNSmasq DNS & DHCP is working on assigning IP address to the devices on my network via DHCP. However, some devices have been assigned statis IPs using their MAC addresses and have been added to the "Hosts" list but when I configure them to obtain IP address via DHCP, they got assigned dynamic IP addresses within the DHCP range.

Devices which are supposed to be assigned static IP addresses ranged from 192.168.1.3 to 192.168.1.5x.
DHCP range has been set from 192.168.1.3 to 192.168.1.245.

to supplement, some devices could obtain the static IPs from the Hosts list, some obtained the dynamic IPs such as TP-link network switch and an IPcam. dunno why.

Please help me resolve the issue. Otherwise, please provide a step by step tutorial on how to configure DNSmasq DHCP server.  Thank you.

Well... at least that part is good :)

Could be because of the fact that you can not do a DHCP IP Release on those last two devices ?!

And just to be sure : You did click APPLY after making all the Static DHCP IP Address Mappings ?
I forgot a couple days ago while changing some stuff... It was really awkward! :)



By the way :
I would always configure all important devices on the network with a Static IP Address in their own Operating System or some kind of webGUI and consider the Static DHCP IP Address Mapping as the backup option in case the device somehow loses it's configuration !!

So stuff like :
- Routers
- Switches
- Accesspoints
- Any kind of Servers like NAS devices or DNS Filtering instances either VM/Container based (Proxmox!) or Bare metal ones.

I have all my static mappings outside of the DHCP ranges. IP assignments works without any issues with this.

I know, this is not really recommended according to the docs, but I had it this way before in ISC and just configured it the same way as I migrated to Dnsmasq DNS & DHCP.
