Can hosts get customized option value when they use DHCPINFORM messages?

apparently not. this causes consternation when clients are initially given a custom value at the initial lease and the dhcp inform changes it to a default as you observed. the best solution I have found is to tell the server it is not authoritative for subnets affected by this. version 4.x.x is required for this to work but contrary to the documentation will successfully ignore the troublesome dhcpinform requests.

Subject: Can hosts get customized option value when they use DHCPINFORM messages?

Hi~

Does anyone know if we can let different clients get different option value when they query the DHCP server using DHCPINFORM message?

I know that we can let a client get customized configuration(different option values) using keyword "host".
But it seems not work when the client uses DHCPINFORM message to query the server. When I try it, the server always gives me the configuration in the subnet. Can I let the server return the configuration based on the MAC address even when the client use DHCPINFORM?

Thanks,
