Andreas,
If you can easily build dnsmasq from source, please could you try
applying the patch below, and see if that fixes the problem?
Cheers,
Simon.

I am using dnsmasq 2.91 un a Raspberry Pi 5 (Arch Linux Arm). To declutter my
config I have moved my dhcp-hosts to a dhcp-hostsfile and found an
inconsistency.
While in the config a declaration such as dhcp-hosts=AA:BB:CC:DD:EE:FF,set:name
still considers the settings in the system hosts/ethers-file for IP-assignment
a declaration in a hostsfile of AA:BB:CC:DD:EE:FF,set:name gives the device a
new IP (.42 instead of .11) and logs:
Jun 27 16:05:17 raspberry dnsmasq-dhcp[419]: Name iPhone wurde dem DHCP-Lease
von 192.168.188.42 nicht zugewiesen, da der Name in /etc/hosts bereits mit
Adresse 192.168.188.11 existiert
Aside of the IP everything works, dhcp-options defined in an optsfile are
respected. This would confirm MAC-address is correct (it was also copied/pasted
while transferring to new files).
Adding the desired IP to the dhcp-hostsfile
(AA:BB:CC:DD:EE:FF,set:name,1.2.3.4) resolves the problem but this would be a
double configuration. Also, there's then a warning logged:
Jun 27 16:21:28 raspberry dnsmasq-dhcp[410]: doppelte IP-Adresse 192.168.188.15
(iphone12) in "dhcp-config"-Anweisung
Please have a look, thank y
