One way to avoid the temp file is to use Perl instead of AWK:

for i in `find . -name '*.html'`; do perl -pi -e 's/207\.106\.32\.241/ancss.org/g' $i; done

This is also a bit more efficient since it's only reading each file
once instead of twice as in your method.

See perldoc perlrun for documentation on perl's -p  and -i parameters.
