[Dnsmasq-discuss] dhcp option 43 question

OK, so I'm still confused.  Is it assumed that if I use 
dhcp-option=vendor... that it is option-code 43 (because we've specified 
a vendor-specific option)?  I don't exactly understand how your 
recommendation maps back to the examples given in that reference webpage.

BTW: On that webpage, it would appear that the vendor string I want to 
use is "ubnt", right?  So in order to not send this option to all my 
other dhcp clients, I would use "dhcp-option=vendor:ubnt,..." right?

Thanks again for the help!
