Domainwatchdog 🐶

Domainwatchdog helps you to determine the availability of domains.

Setup

go install github.com/joeig/domainwatchdog/cmd/domainwatchdog@latest

Usage

$ domainwatchdog -domains "example.com,example.net,example.org,example5928474.de"
status of domain "example.com": "domain is given"
status of domain "example.net": "domain is given"
status of domain "example.org": "domain is given"
domain "example5928474.de" is available: "domain not found"

Domainwatchdog performs a whois lookup and matches the result with commonly used patterns that indicate if a certain domain is given or available.

Exit codes

The exit codes harmonize nicely with Icinga's check plugin API.

Code	Description
0	All domains are given
1	Fatal error
2	At least one domain is available1
3	Unknown error

Footnotes

1. If one domain is available but another one has a different status, exit code 2 has precedence. ↩
