I would agree that a reboot is optional. But I would suggest that it's probably a good idea to reboot now, during configuration. If you have to reboot at a later date when the system is "in production", and your system does not come up on the expected IP, or there's a typo in the default route or something, that could cause a bigger problem. Just because ifconfig, although it's a legacy tool, doesn't respect Mac OS X procedure when changing things, for example configd is not aware of your changes and preferences.

This is what actually does the work behind the scenes. Evedience of ifconfig usefulness is of all people MSFT.
Windows until had winIPcfg a gui program. It works very similar to ifconfig. Also note that Longtooth is supposed to include a proper commandline and shell called MSH. If command line programs are legacy then why is MSFT just now impleneting it as a feature. You may consider whatever you want but using ifconfig only is not recommended by Apple as it doesn't inform all the frameworks of the changes made. If it was the good tool why would Apple develop tools that you can find in Mac OS X Server to change network configuration? If you want to consider ifconfig is your tool, make it your way, I don't mind at all, but I don't recommend it, that's all, just as Apple does itself I use ifocnfig only for reading things about my config, never to modify it.

And yes I consider it as a legacy tool as many unix users expect to find it although it has lost most of its interest as Apple developped a much more interesting system to manipulate network configurations. It's called high-level vs low-level. It doesn't send out notifications, update configd, or do anything else, because it doesn't need to.
It interacts with many parts of the operating system, but, when it's time to change the actual IP address of the card, configd and friends just call ifconfig to do the dirtywork. Apple wrote configd and such in order to create an easier way to use ifconfig and its friends, arp, route, etc. Reading this: I agree that configd is higher-level thant ifconfig but, again according to that document, the work done whenever you click on the "Apply" button in your Network Preference Pane or whenever you switch from a net config to another is a little bit more complex than just launching ifconfig.
Again, do what you want, I don't mind, but don't be surprised if what you set from ifconfig is changed by configd, which can happen, sometimes I would also think 'ifconfig' is the way to go on this. I speculate that the only way the change in the preference. There is no doubt that you can change the IP without rebooting.
I use various location settings on my TiBook and prefer to sleep it to 'refresh' all apps as some things mail, remote control apps, etc get confused. However, this seems much less an issue these days.
Set an IP Address
I would think a reboot would be more critical on an OS X server as it is picky about having nameservice running and configured. So, changing the IP may mean that it does not gracefully reconfigure the host name. There's a much simpler way. You set up 2 locations, one with each IP you want. Use the command "scselect" to change locations. I need to assign static IP address with shell script. I tried ipconfig. It only works half way. The change was propagated by configd.
