```

above is my logstash configuration:

below is my ip.txt file  
10.12.7.0-10.12.7.24  
10.13.7.0-10.13.7.24

That's not the right notation for CIDR. You need two CIDR patterns, 10.12.7.0/28 (which includes 0 to 15) and 10.12.7.16/29 (which includes 16 to 23). Together they include 24 addresses. If you really want .24 as the 25th address then you need a third -- 10.12.7.24/32.
