Roger has already provided a few solutions, and QM has a good answer, but here's another:

    my %newhash1 = map  { $_=>$hash{$_} }
                   grep { /^NETWORK/    }
                   keys %hash;

I'm not sure how all these compare in terms of speed, efficiency, etc. This is just how I'd do it for greatest clarity.
