ipconfig /registerdns for osx?

Is there a similar command to wintel's "ipconfig /registerdns" for OS X?

Yea. I was wondering what the terminal command would be for registerdns, particularly when the computer is connected to an Active Directory domain.

In System Preferences -> Network press "Renew DHCP Lease".

Or do you want a CLI command?

Well, there is actually an ipconfig CLI command! ( man ipconfig tells you all about it.) The command

sudo ipconfig set en0 DHCP (case is important---'DHCP' not 'dhcp')

will do a DHCP lease renew, with all the attendant DNS renewing. I imagine that there is a more direct way to do what you want using dscl, the Directory Services command line interface (again,

man dscl

for details).

What is the problem that you are you trying to solve?
