Option 28 specifies the broadcast address in use on the client's subnet, but I'm trying to figure out why/when to use it. I have a client device asking for the option and complaining when it doesn't receive it even though it seems to function on the LAN just fine. After some research it looks like some DHCP servers don't send this Option by default, but since most client devices don't seem to have an issue without it, it got me wondering: Shouldn't the device be able to figure that out on its own after receiving its IP & Subnet Mask? Is this something I should be ensuring is configured in my DHCP servers?
