I would like to use my DHCP server to give information about some local services like ntp, using DHCP options as explained in the dhcp-options(5) manpage.
Does anyone here know, or is there a good document on the net, which options I can reasonably expect clients on different operating systems to know about? I imagine that things like "option font-servers" will be ignored by Windows and Mac DCHP clients because their host OS's don't use X11 fonts, but how about ntp-servers, smtp-server, subnet-mask or similar?
