Why is DHCPD offering wrong lease times? I have DHCPD on OpenBSD 5.8 running and experiencing a weird issue. I set the lease time as follows in /etc/dhcpd.conf: max-lease-time 7200; default-lease-time 7200; This should be 2 hours. When I check my dhcpd.leases file, I see this: lease 172.24.186.224 { starts 5 2018/07/31 07:17:03 UTC; ends 5 2018/07/31 19:17:03 UTC; hardware ethernet b4:f6:1c:27:4f:a4; uid 01:b4:f6:1c:27:4f:a4; client-hostname "Apple"; } This 12-hour lease time also checks out when doing a tcpdump and analyzing with Wireshark. (There are also some 24-hour lease times in the dhcpd.leases file which I can not explain either.) I tried to set the max-lease-time and default-lease-time either in the "toplevel" config or for a specific subnet with no luck. What is going on here?

I just found the solution.

It seems to be a bug in this specific OpenBSD version:
