DESCRIPTION

ripcalc can read IPv4/IPv6 addresses from command line or standard input and output different formats or associated networks from CSV .

ripcalc can format network addresses, find matches in CSV or process a list.

ripcalc can convert input addresses that are in other number formats such as hex or octal.

Given a list of IP addresses, print only those that match the network. When s and inside are used, only addresses from -s are printed if they are that are inside of the input IP network from the command line. This can be reversed with --outside , (e.g. ripcalc -s - --inside 192.168.0.0/16 ).

When -a is used, addresses read from -s will not be shown when listing -l a network, showing only available addresses.

When --reverse is used the inputs , sources or both can be treated as back-to-front.

ripcalc can return a list of subnets when a network is provided along with the divide argument and a subnet CIDR mask.

When --encapsulating is used the containing network will be returned.

CSV

Network matches can be returned from a CSV .

$ cat nets.csv
network,range,owner
rfc1918,192.168.0.0/16,bob
rfc1918,172.16.0.0/12,cliff
rfc1918,10.0.0.0/8,mr nobody
$ ripcalc --csv nets.csv -i range --format '%{owner}\n' 192.168.0.0
bob

Addresses can be read via file or from stdin (-):

$ cat list
127.0.0.1/28
10.0.0.1/28
192.168.1.1/30
172.18.1.1/30
10.0.0.0/30
$ ripcalc --csv nets.csv -i range --format '%{range} %{owner}\n' -s list
10.0.0.0/8 mr nobody
192.168.0.0/16 bob
172.16.0.0/12 cliff
10.0.0.0/8 mr nobody

FORMAT

% denotes a format control character, followed by one of the following:

Additional characters prefixing the above placeholder can control the representation:

Other format characters:

%xa gives the address in hex, or %Sa to return the binary address, split at the network boundary.

When using CSV fields can be matched by name when network matched:

--format '%{name}'

inside/outside

When --inside or --outside are given addresses that match --file are printed. If no matches are found ripcalc will exit non-zero.
