I knew what you meant by "IP". But:

    1. Once a missle is launched the any wired "IP" is no long a valid 
       port.  
    2. Wireless IP is no good, do to hacking during flight. Do not want 
       a hacker forcing a 180 degree turn or having that missle just 
       land so they can use it against someone else. Do you?

Which means that the system must be able to operate without human 
connection except for the system kill switch after launch. So, besides 
the radio port for the "Kill" command, the missle has to be disabled 
any and all humand connection, that include any and all IP subsystems.  
So, it must rely on the radio GPS system to calculate the position of 
itself and the target.  

Plus, the gov't is perfect for wasting tax payer money even if it borrowed 
from any country.
