I submit that if your environment is at all like mine, you don't actually 
configure 192.168.whatever addresses on the equipment in your house. You 
run DHCP within the home and it assigns such. That being the case, you 
actually don't know or care what the addresses are on your equipment. You 
care that your SIP Proxy and etc know the relationships, and they derive 
them directly without your intervention.

Actually, I do set up static addresses.  I'd use DHCP, but if I did that
I would not be able to refer to the machines on my local net by name.

I do hope that you know you can assign 'static' addresses based on MAC
address and a number of other properties that the dhcp client provides.
The dhcp server will then just assign the configured prefix. This is
actually what most ISP's use, but they will only give people one IP.

Until my DHCP client can update my DNS tables with name information
on the fly, I'll keep doing doing it this way.  Apple's zeroconf 
technology solves this problem, albeit in a slightly different way,
but Linux doesn't deploy it yet.

Even Windows can do that ;)

But so can any UNIX or basically anything where you can compile bind
utils on:

or the exact same thing but for Windows:
