ipv6calc - format, calculate, show information, filter IPv6/IPv4/MAC addresses

ipv6calc [OPTIONS] [<input data>]

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

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]

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

IP2Location support disabled
[--db-ip2location-dir DIRECTORY]
IP2Location database directory (default: /usr/share/IP2Location)
GeoIP support disabled
[--db-geoip-dir DIRECTORY]
GeoIP database directory (default: /usr/share/GeoIP)

Special options:

be more quiet (auto-enabled in pipe mode)
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> [...]
input data
[-m] -I|--in -?|-h|--help
[-m] -O|--out -?|-h|--help
[-m] -A|--action -?|-h|--help

Other usage:

show information about input data
show available types on '-m'

Usage with shortcut options: <shortcut option> [<format option> ...] <input data>

To run this program the standard way type:

ipv6calc --showinfo -i -m ::1

ipv6calc --showinfo -m

ipv6calc --showinfo --show_types

ipv6calc --ipv4_to_6to4addr

ipv6calc --addr_to_uncompressed ::1

Usage of filters in pipe mode:

cat <Apache-Logfile> | ipv6calc -E ipv6.db.cc=US,iid-random
