Remove the quotes ("").

You have been caught by the different levels of escaping. The quotes
cause one level of escaping, and the expansion causes another level. So
the regular expression you are actually tring to match is

^192.168.100.d+

which isn't right. You don't need the quotes, so get rid of them.
If you are using Exim 4, and alternative approach to doubling the \\ is
to use \N to suppress escaping in the expansion.
