IP-bereik naar CIDR.
Zet IP-bereiken, adreslijsten en overlappende blokken om in zo weinig mogelijk CIDR-blokken, met uitsluitingen en een omvattend supernet.

- Overlapping and adjacent entries are merged first, then each range is split into the fewest aligned blocks.
- Comments after # are ignored. Commas or semicolons can separate several entries on one line.

Technische opmerkingen in het Engels
Up to 5,000 lines; IPv4 and IPv6 can be mixed. The single supernet may include addresses that were not in the input. Everything is calculated in your browser; nothing is sent or probed on the network.
Entries are converted to start–end ranges, merged when they overlap or touch, reduced by the exclusions, and each remaining range is cut into the largest aligned power-of-two blocks.
192.168.1.0 – 192.168.1.130 becomes 192.168.1.0/25, 192.168.1.128/31 and 192.168.1.130/32; 10.0.0.0/25 and 10.0.0.128/25 merge into 10.0.0.0/24.
