[dhcwg] RE: Free Options

["Bernie Volz (volz)" <volz at cisco.com>]

Yes, I did find (or was providing some information) about these options:

249		Windows XP clients request option 249.
252		MAC OS X clients request option 252.

But as they are outside the RFC 3942 reclassified range, there was no point in doing anything about them.

Ruben - Take a look at RFC 2131, RFC 2132, RFC 3942 and http://www.iana.org/assignments/bootp-dhcp-parameters 
  for details about option codes available for private use.

Executive summary - with some exceptions, option codes 224-254 are  
available for private use.  I don't recall the details; I think the  
two option codes you mentioned are known to be in unofficial use, but  
they don't seem to be documented in http://www.iana.org/assignments/bootp-dhcp-parameters 
.  Bernie - did you receive any information about 249 and 252 in your  
followup to RFC 3942?
