I'm running ISC DHCP 3.0.1 (yes old I know) and have recently experienced a strange thing when some clients are requesting to extend the lease. I have a failover solution and in some cases both servers answers the DHCPREQUEST with an DHCPACK on the same IP address even though, naturally, only one of them are specified in the option 54 field (DHCP-server-identifier). I cannot explain this and I am curious if there is anyone that can explain this or is it a bug?
