IPv4 / IPv6 Route Aggregator
Aggregate mixed IPv4 and IPv6 prefixes into the smallest exactly equivalent route sets for each address family.
This tool handles input and primary processing in your browser and is designed not to send the input to QuickKit’s server.
Aggregated IPv4
Aggregated IPv6
The result covers exactly the input address set; no gap-filling summary is added.
How it works
Aggregates IPv4 and IPv6 independently and returns the smallest CIDR lists covering exactly the same address sets. Adjacent prefixes merge only when the merged prefix introduces no extra addresses. This is lossless set aggregation, not a broader operational summary route. Bare addresses become /32 or /128; host bits are normalized and reported. Invalid entries are skipped and listed. Up to 5,000 entries.
