Synopsis

ipv6calc [OPTIONS] [<input data>]

Description

This program formats and calculates IPv6/IPv4/MAC addresses and can do many more tricky things, e.g. includes a pipe filter capability.

Options

If no data is presented as command-line arguments, data is read from standard input.

General options:

[-d|–debug DEBUGVALUE]

debug value (bitwise like) can also be set by IPV6CALC_DEBUG environment value

[-v|–version [-v [-v]]]

version information (2 optional detail levels)

[-v|–version -h]

explanation of feature tokens

[-V|–verbose]

be more verbose

[-h|–help|-?]

External database options (depending on compiled-in suppport):

[–db-ip2location-disable]

IP2Location support disabled

[–db-ip2location-dir DIRECTORY]

IP2Location database directory (default: /usr/share/IP2Location)

[–db-geoip-disable]

GeoIP support disabled

[–db-geoip-dir DIRECTORY]

GeoIP database directory (default: /usr/share/GeoIP)

Special options:

[-q|–quiet]

be more quiet (auto-enabled in pipe mode)

[-f|–flush]

flush each line in pipe mode

Usage with new style options:

[–in|-I INPUT-TYPE]

specify input type (default: autodetect)

[–out|-O OUTPUT-TYPE]

specify output type (sometimes: autodetect)

[–action|-A ACTION]

specify action (default: format conversion, sometimes: autodetect)

[<format option> …]

specify format options

<input data> […]

 Other usage:

–showinfo|-i [–machine_readable|-m]

Examples

To run this program the standard way type:

ipv6calc –showinfo -i -m ::1

ipv6calc –showinfo -m 127.0.0.1

ipv6calc –showinfo –show_types

ipv6calc –ipv4_to_6to4addr 127.0.0.1
