The reason for the loss of the 10.x.x.x is due to some improvements behind the scenes that implement some additional NAT fuctions.  The tradeoff was the loss of the class A block of addresses.  I'm sure it was a decision made that normally would not cause issues for many customers, but of course there's always one or two who are effected by it (see Port 443 issue with wireless STB).  Though the one thing I'm looking forward to is the hopefully fixing the wireless dropping issue.
