Which DHCP Client OS Support DHCP Option 119 Domain Suffix Search?
The ability for DHCP servers (Microsoft, ISC, VitalQIP, IPControl, Infoblox, etc.) to deliver DHCP Option 119 - Domain Suffix Search Lists has been around for a long time. Initially, DHCP Client Support for this option was scarce. So, my question is this: Which DHCP Client Operating Systems support the use of DHCP Option 119 sent from a DHCP server?
I am specifically looking for Mfg, and family/version/release info.
Solution 1:
I'm constraining my search to Microsoft OS's tonight, for lack of energy. >smile<
Finding a concise list of the DHCP options supported by various Microsoft operating systems has proven to be difficult. The following article shows as being revised in 2006, and references Windows XP in the article text, but claims to only apply up to Windows NT 4.0.

Based on this article, it doesn't appear that any version of Windows referenced in that article supports option 119. I'm seeing postings that seem to indicate that Windows Server 2003 and 2008 do not support option 119, either.
This article indicates that DHCP option 119 doesn't work on Windows 2000 - Windows Server 2003:

I'll try my Windows 7-based laptop computer in a moment and drop an edit in here with my findings.
Solution 2:
Option 119 works with Linux ISC DHCP Client/Server Version 3.1.1 - at least on Debian Lenny. Also our MacOS X Client's (10.6) get the correct search list. Linux Clients do construct the search list from domain-name and domain-search, MacOSX seem to ignore domain-name when constructing the search-list, if domain-search is available. It's probably possible to configure Solaris to understand Option 119 too, with some work.
Solution 3:
Windows 7 does not request DHCP option 119.
Ubuntu 11.10 does. (both Desktop and Server editions)
