domain-availability checker

Check domain name for availability on every Top-Level-Domain.

green means domain available 👍
red means domain not available 👎

This downloads a list of TLDs from IANA, so it should always be up to date.

Note: A domain will be reported as available when your (specified) DNS server states that the domain does not exist (NXDOMAIN). A domain will also be reported as not available when the DNS server times out.

Setup

clone the repo:

git clone [email protected]:mrchenliang/domain-availability.git

navigate into the folder:

cd domain_availability

give it execution permission:

chmod +x ./domain_availability.sh

Usage

./domain_availability.sh <domain> [DNS server]

Examples

Check domain availability:

./domain_availability.sh doge

Write only available domains to file:

./domain_availability.sh doge | tee available.txt
