You on a dialup?  If so your dialup scripts might be changing it, mine used 
to do that and not instantly either, they did it when they felt like it.  I 
haven't used a dialup for years, but it is all tucked away in /etc/ppp 
somewhere ...  pppconfig will guide you to it in the advanced 
options.  Also there might be some stray 'up' lines in 
/etc/network/interfaces for the ppp0 interface (less likely).
