[X4U] IP address on local network

[Neil Laubenthal]

Sure . . .just go into Networking and set up static IPs for each  
machine. You'll either have to completely disable DHCP on your Airport  
or else change the scope of IPs that might be assigned to not include  
the ones you have set up for static.

For instance . . . if your airport is currently distributing  
192.168.1.2 through 192.168.1.254 . . . just change that to only  
distribute say .1 through .25 and then assign static IPs to your Macs  
starting at 26.

Alternatively . . . you could set the DHCP lease for 999 days or  
something like that . . .that way the IPs could be dynamically  
assigned but would never change.

Alternatively . . .although this is getting pretty geeky you could  
just set up lease reservations in your Airport based on MAC address  
and then each computer will always get the same dynamically assigned  
IP address . . . giving you all the benefits of DHCP and all the  
benefits of static IPs at the same time.
