According to the Mac OS X man page, Using ipconfig with INFORM requires the use of an IP address and an explicit subnet mask. However, sadly, I’ve found that INFORM doesn’t work as advertised.

Have you actually tried this out and found that it worked? Using ipconfig…INFORM, have you ever actually set an IP address statically and yet actually received DHCP option information, like DNS settings, that stuck?

In my experience, at least on Mac OS X 10.6.5, using INFORM works exactly like setting MANUAL and doesn't actually use DHCP to set any of the other networking options.

Also, what's with the "Renew DHCP Lease" button disappearing in the System Preferences Networking preference pane GUI when "Use DHCP with manual address" is selected? Grr….

ipconfig is a mac os x command-line utility for manipulating DHCP leases, including the DHCP with manual address (which is the INFORM option).

/usr/sbin/networksetup will do all this and more. Think of networksetup as a command-line equal to Network Preferences.

Hi,
ipconfig – it’s a command from the windows, or something I don’t know. Please correct me if I’m wrong

“sudo ipconfig set en1 INFORM 192.168.0.150″ – is this then permanent, i.e. the equivalent of manually setting it in the Network pref pane?
