# cidr
|
|
|
|
This tool reports ip address ranges for a collection of CIDRs, and then reports
|
|
if there is any overlap.
|
|
|
|
The official package name is [mcquay.me/cidr](https://mcquay.me/cidr?go-get=1).
|
|
|
|
## usage
|
|
|
|
```bash
|
|
# prints range
|
|
$ cidr 10.0.0.0/24
|
|
10.0.0.0 10.0.0.255 256
|
|
|
|
# range plus no error for overlap:
|
|
$ cidr 10.0.0.0/24 10.0.2.0/24
|
|
10.0.0.0 10.0.0.255 256
|
|
10.0.2.0 10.0.2.255 256
|
|
|
|
# error on overlap
|
|
$ cidr 10.0.0.0/24 10.0.0.5/32
|
|
10.0.0.0 10.0.0.255 256
|
|
10.0.0.5 10.0.0.5 1
|
|
overlaping networks: 10.0.0.5/32 overlaps with 10.0.0.0/24
|
|
$ cidr 10.0.1.0/24 10.0.0.0/16
|
|
10.0.1.0 10.0.1.255 256
|
|
10.0.0.0 10.0.255.255 65536
|
|
overlaping networks: 10.0.1.0/24 overlaps with 10.0.0.0/16
|
