CLI CIDR calculator for IPv4 and IPv6

Calculate Network Ranges for a given CIDR (IPv4 and IPv6)

For example, cidit 10.122.33.44/24 prints out the following information:

 ip_ver   cidr              address        prefix   network       first_usable   last_usable     broadcast       available   netmask   hostmask
 v4       10.122.33.44/24   10.122.33.44   24       10.122.33.0   10.122.33.1    10.122.33.254   10.122.33.255

CIDR stands for Classless Inter-Domain Routing. Learn more about CIDR here or here.

cidit 10.122.33.44/24 10.255.55.66/20 2001:db8:1::ab9:c0a8:102/64

Output:

Different output formats

cidit -f json 10.122.33.44/24
# Prints: {"version":2,"data":[{"ip_version":"v4","cidr":"10.122.33.44/24","address":"10.122.33.44","prefix_length":24,"first_usable":"10.122.33.1","last_usable":"10.122.33.254","network":"10.122.33.0","broadcast":"10.122.33.255"}]}

Pretty print:

cidit -f json -p 10.122.33.44/24

Output:

{
  "version": 2,
  "data": [
    {
      "ip_version": "v4",
      "cidr": "10.122.33.44/24",

      "broadcast": "10.122.33.255"
    }
  ]
}
