CIDR Aggregator

Merge multiple CIDR ranges into minimal supernets — optimize firewall rules and routing tables

How to Use CIDR Aggregator

1. Paste or type one CIDR range per line in the input box, for example: 192.168.1.0/24, 10.0.0.0/16
2. Click Aggregate to merge overlapping and adjacent CIDR ranges into the minimal set of supernets
3. Review the aggregated result — each line shows the original CIDR range and total host count. Use Copy Result to copy all aggregated CIDRs at once
