Domains list

This is a collection of all domain names that currently exist on the internet and have an SSL certificate. This covers about 52% of all domains on the internet. The list is usually updated daily.

It is created by watching multiple certificate transparency logs, which contain information about every SSL certificate that is issued, including the domain names that it was issued for.

Public TLDs

This list includes all domains that are registered under offical top level domains.
For example: *.com, *.co.uk, *.apple.

You can search through this dataset easily in the browser at domainsearch.connorlanigan.com.

Private TLDs

This list includes all domains that are provided as registrable subdomains of existing registered domains.
For example: *.duckdns.org, *.myfritz.net, *.direct.quickconnect.to.
