TLD 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.

Usage

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

Examples

Check domain availability:

./tld_checker.sh doge

Write only available domains to file:

./tld_checker.sh doge | tee available.txt
