-Hath does just that. It takes as its input (via stdin, or a file with
-the -i parameter) a list of CIDR blocks.

Without \fB\-\-barriers\fR, you can match things you shouldn't:
.nf
-.I $ echo \(dq127.0.0.100\(dq | grep -P $(hath <<< \(dq127.0.0.1/32\(dq)
+.I $ echo 127.0.0.100 | grep -P $(echo 127.0.0.1/32 | hath)
127.0.0.100
.fi
Using \fB\-\-barriers\fR can prevent this:
.nf
-.I $ echo \(dq127.0.0.100\(dq | grep -P $(hath -b <<< \(dq127.0.0.1/32\(dq)
+.I $ echo 127.0.0.100 | grep -P $(echo 127.0.0.1/32 | hath -b)
