Check domain availability on all TLDs

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

tld_checker's Issues

Not working anymore

Hi, thanks for sharing the script. Unfortunately, it's not working, tried on Ubuntu 17.10 and Debian 9. Seem's it's something in this part:

workers=32
for i in $(seq $((workers-1)) 0); do
  for tld in $(echo "$tlds" | awk "(NR+$i) % $workers == 0"); do
    check_tld "${1}.${tld}"
  done &
done

I replaced this function with the one in the previous commit and it worked without color in output and there's a strange suffix ^[(B^[[m after every line. I'm trying to figure out why, but I don't know much of bash.

Changing setf to setaf fixed the color issue for me.

function check_tld {
  if [ -z "$(dig +short SOA "$1" $dns)" ]; then
    echo "$(tput setf 2)${1}$(tput sgr0)"
  else
    echo "$(tput setf 4)${1}$(tput sgr0)" >&2
  fi
}

1-char and 2-char

Hey,

Nice tool, however, it will report a domain available eventhough the NIC has a rule of, eg, 3 characters as minimum. Does IANA have a similar list or info about which TLDs will block registration of 1-char and 2-char domain names? If so, it would be cool to have it built into this tool.

Thanks!
