Domains Project: Processing petabytes of data so you don’t have to
World’s single largest Internet domains dataset
This public dataset contains freely available sorted list of Internet domains.
You can support this project by doing any combination of the following:
- Posting a link on your website to DomainsProject
- Sponsoring this project on Patreon
- Opening issue and attaching other domain datasets that are not here yet (be sure to scroll through this README first)
- 10 Million
- 100 Million
- 1 Billion
- 1.7 Billion
(Wasted) Internet traffic:
- More than 1TB of Internet traffic is just 3 Mbytes of compressed data
- 1 million domains is just 5 Mbytes compressed
- More than 5.7PB of Internet traffic is necessary to crawl 1.7 billion domains (3.4TB / 1 million).
- Only 4.6Gb of disk space is required to store 1.7 billion domains in compressed form
- 1Gbit fully saturated link is good for about 2 million new domains every day
- 8c/16t and 64 Gbytes of RAM machine is good for about 2 million new domains every day
- 2 ISC Bind9 instances (>400 Mbytes RSS each) are required to get 2 million new domains every day
- After reaching 9 million domains repository was switched to compressed files. Please use freely available XZ to unpack files.
- After reaching 30 million records, files were moved to
/dataso repository doesn’t have it’s README at the very bottom.
This repository empoys Git LFS technology, therefore user
has to use both
git lfs and
xz to retrieve data. Cloning procedure is as follows:
git clone https://github.com/tb0hdan/domains.git cd domains git lfs install ./unpack.sh
Getting unfiltered dataset
For Patreon subscribers raw data is available at https://dataset.domainsproject.org.
wget -m https://dataset.domainsproject.org
After unpacking, domain lists are just text files (~49Gb at 1.7 bil) with one domain per line.

Search engines and crawlers
Domains Project bot
Domains Project uses crawler and DNS checks to get new domains.
DNS checks client is in early stages and is used by select few. It is called Freya and I’m working on making it stable and good enough for general public.
HTTP crawler is being rewritten as well. It is called Idun
Typical user agent for Domains Project bot looks like this:
Mozilla/5.0 (compatible; Domains Project/1.0.8; +https://domainsproject.org)
Some older versions have set to Github repo:
Mozilla/5.0 (compatible; Domains Project/1.0.4; +https://github.com/tb0hdan/domains)
Starting with version
1.0.7 crawler has partial
and rate limiting. Please open issue if you experience any problems. Don’t forget to include your domain.
Yacy is a great opensource search engine. Here’s my post on Yacy forum: https://searchlab.eu/t/domain-list-for-easier-search-bootstrapping/231

This dataset can be used for research. There are papers that cover different topics. I’m just going to leave links to them here for reference.
