# cidr
> Simplifies IPv4/IPv6 CIDR network prefix management with counting, overlap checking, explanation, and subdivision.
> More information: <https://github.com/bschaatsbergen/cidr>.
- Explain a CIDR range:
`cidr explain {{10.0.0.0/16}}`
- Check whether an address belongs to a CIDR range:
`cidr contains {{10.0.0.0/16}} {{10.0.14.5}}`
- Get a count of all addresses in a CIDR range:
`cidr count {{10.0.0.0/16}}`
- Check whether two CIDR ranges overlap:
`cidr overlaps {{10.0.0.0/16}} {{10.0.14.0/22}}`
- Divide a CIDR range into a specific number of networks:
`cidr divide {{10.0.0.0/16}} {{9}}`
