# 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}}`
