| # Desearch domains |
|
|
| The domains in scope for crawling by [Desearch](https://www.desearch.ai), Bittensor subnet 22. |
|
|
| ## Contents |
|
|
| `domains/domains.parquet` |
|
|
| | column | type | description | |
| | --- | --- | --- | |
| | `host` | string | Registrable domain (eTLD+1), lowercase, without scheme or `www.` | |
|
|
| ## Sources |
|
|
| The union of six public domain rankings, each entry resolved to its registrable domain using the |
| Public Suffix List: |
|
|
| - [Tranco](https://tranco-list.eu/) |
| - [Majestic Million](https://majestic.com/reports/majestic-million) |
| - [Open PageRank](https://www.domcop.com/openpagerank/) |
| - [BuiltWith Top 1M](https://builtwith.com/top-1m) |
| - [Cisco Umbrella Popularity List](https://umbrella-static.s3-us-west-1.amazonaws.com/index.html) |
| - [Cloudflare Radar Top 1M](https://radar.cloudflare.com/domains) |
|
|
| ## Filtering |
|
|
| Removed from the union: |
|
|
| - Country-code TLDs outside English-speaking markets |
| - Adult, gambling, malware, phishing, cryptojacking, stalkerware, warez, hacking and DDoS domains |
| - Banking portals, URL shorteners, redirectors, advertising and tracking endpoints, dynamic DNS, |
| DNS-over-HTTPS resolvers and residential proxies |
| - Social networks, forums, chat, webmail and file hosting, where pages are generated per user |
| rather than published |
| - CDNs, certificate authorities, registrars and other infrastructure hostnames |
|
|
| Classification uses the [UT1 blacklists](https://dsi.ut-capitole.fr/blacklists/) from Université |
| Toulouse 1 Capitole together with public adult-domain blocklists. |
|
|
| Every surviving domain is then checked twice more: |
|
|
| - **It must resolve.** A domain with no address record is dropped. Rankings are built from |
| historical traffic, so a meaningful share of any of them has since lapsed. |
| - **It must serve under its own name.** A domain that redirects to a different registrable domain |
| is dropped in favour of its destination. Listing both would send two crawlers to one server |
| under two names, and would give the same pages to two different miners. |
|
|
| Inclusion means a domain passed all of these. It does not mean the domain has been crawled. |
| `robots.txt` is read and obeyed at request time, and a domain that disallows the `DesearchBot` |
| token is never fetched. Domains that later prove unreachable, disallow `DesearchBot`, or publish |
| in a language other than English are dropped when the list is next updated. |
|
|
| ## Crawler |
|
|
| Desearch identifies as `DesearchBot` and signs its requests with |
| [Web Bot Auth](https://developers.cloudflare.com/bots/concepts/bot/verified-bots/web-bot-auth/), |
| so operators can cryptographically verify the traffic. Requests to a host are sent no more than |
| one per second, and less often where `robots.txt` specifies a longer `Crawl-delay`. |
|
