dnstools

A collection of tools to filter and manipulate domain names on standard input.

Installation

Make sure go is installed through your distro. You can install all the tools with:

$ go install github.com/ynadji/dnstools/...@HEAD

Usage

nld

nld changes domain names on stdin to their nth level domain (NLD). For example, the 1LD (TLD), 2LD, 3LD, and 4LD of foo.bar.google.com are com, google.com, bar.google.com, and foo.bar.google.com, respectively. nld uses the public suffix list so it is aware to treat co.uk as a TLD rather than naively splitting on ..

¡ nld --help
NAME:
   nld - nld < domains.txt > nlds.txt

USAGE:
   nld [global options] command [command options] [arguments...]

COMMANDS:
   help, h  Shows a list of commands or help for one command

GLOBAL OPTIONS:
   --numLevels value, -n value  Domain level to extract (default: 2)
   --ignoreErrors               Silently ignore errors (default: false)
   --usePrivateSuffixes         Treat known private suffixes as TLDs (default: false)
   --ignoreNonIcann             Ignore domains with TLDs not known by the PSL (default: false)
   --exactOnly                  Only keep domains if exactly matches label level (default: false)
   --help, -h                   show help (default: false)

dclean

dclean filters or maps domain names on stdin based on common validations and transformations.

¡ dclean --help
