I am creating code that makes decisions based on the result of the
Request.UserHostAddress. Is there a way I can search on /CIDR or range of IP
addresses without specifying an exact search string, i.e. one string for
each IP address? You can imagine why I don't want to have to create a
CASE/ELSE for this scenario...
I'm open to any suggestions.

I presume you're guaranteed what the IP addresses are, and that they won't
ever change or be placed behind a NAT box or something that will change the
IP addresses? Or that the subnet setup won't change?
Why not identify machines with something like an X.509 certificate, which is
_meant_ to be identifying? IP addresses aren't actually meant for that
purpose.

Actually, the IP addresses are from "people" who hit my website. Spiders for
example. So while the address space is fairly constant, it still needs to be
a range of addresses to test for.
Any thoughts?

Impossible mission! How can you tell if it is fake IP or Ip generated by
dhcp ? It makes sense for intranet but not internet.

I don't need to know if the IP address is "real", only that it falls within
a specified subnet.

Maybe what I immediately think of is trivial, but Request.UserHostAddress
returns a string, so can you use regular expression to identify the subnet?
