I think you may have the wrong approach here. See the docs on the use of the <Limit> section ... it pretty much comes out and says not to do what it looks like you're doing :-) [httpd.apache.org...]
The idea of using allow and deny is fine in general, but I think in your case, you want to respond specially to an IP address range by returning a special page. Take a look here in the doc for a couple of approaches to consider. [httpd.apache.org...]
I think you may want to look at RewriteRule and RewriteCond -- the condition is that the requesting IP address matches a range, and RewriteRule would be to send a 403 response and a specific page back.
Take a whirl after reading the docs, and also search here for examples of cases where people have done the same thing. If you're out of luck after that, please let us know what you're trying to accomplish (why is this IP address range special, what kind of message, etc.).
