DHCP problem with static ip

[skoczo]

Hi, I have pihole installed on my proxmox in CT container. I'm facing issue that my static config is not always taken. For example i had new esp8266 device. I installed WLED on it and before connecting to my wifi i added static config for mac address. I see that connecting to wifi takes lot of time and in result ip from DHCP range instead of static config.

Config:

dhcp-authoritative
dhcp-range=192.168.1.150,192.168.1.220,10h
dhcp-option=option:router,192.168.1.1
dhcp-leasefile=/etc/pihole/dhcp.leases
#quiet-dhcp

domain=local

dhcp-host=CC:50:E3:0B:9B:18,192.168.1.21,agatka-lampka2

Do you know what might be an issue? On CC:50:E3:0B:9B:18 dhcp is on. Should i change it to static config? I thought that with static config dhcp server should offer static ip.

PS: other DHCP servers, for example on router, are disabled.

Update: after lease removal and pihole restart proper IP were assigned

Do i need to restart pihole on static ip config change?

The issue seems that Pi-hole's DHCP server does not hand out the dhcp-host defined 192.168.1.21, but an IPv4 address from its dynamic range.

One notable difference here is that the MAC address from the logs is all lower case, while the dhcp-host definition is all upper case.

Despite expecting that to be case-insensitive:
Did you try to change that dhcp-host to lower case yet?

I'm managing pihole via GUI. I did a test and put manually static ip with mac address with lower case. It was converted to upper case. So i think that it is not case sensitive. Interesting thing is that after pihole restart ip were properly assigned.
