IP Interleaver

Group IP addresses by class (A/B/C) and create a round-robin alternating list

Input IPs
Paste IP addresses, one per line. The tool will group them by class and output a round-robin alternating list.
Paste your IP addresses here, one per line. The tool will process them according to your selected method.
How it works: IPs are grouped by network (first 3 octets) and sorted within each group, then interleaved round-robin.
Examples

Interleave Mode:

Input:

140.222.0.12 140.222.0.11 205.172.142.114 205.172.142.113

Output:

140.222.0.11 205.172.142.113 140.222.0.12 205.172.142.114

Sort Mode:

Input:

192.168.1.10 10.0.0.5 172.16.0.1

Output:

10.0.0.5 172.16.0.1 192.168.1.10

Tips

• Invalid IPs are automatically ignored

• Interleave mode groups by network (first 3 octets) and alternates between groups

• Sort mode arranges all IPs numerically from lowest to highest

• Combine mode removes duplicate entries

• Enable "Remove Duplicates" to clean data before processing

• Useful for load balancing, network organization, or data cleanup
