3. Zone Details: .open

.open is a generic top-level domain tailored for initiatives that emphasize openness and accessibility. It is commonly adopted by open-source projects, data and research portals, transparency campaigns, collaborative communities, co‑working spaces, and marketplaces that want to foreground open policies or practices.

As a brand signal, .open conveys collaboration, inclusivity, and a preference for transparent or permission-friendly processes. Organizations choose it to differentiate from commercial or proprietary identities, make purpose explicit in the name, and attract contributors, partners, or users aligned with open values.

Registrations and policy details vary by registrar and registry, so check terms before registering. Consider concise, descriptive names that pair 'open' with a project or sector term, and plan redirects, trademark protection, and consistent social profiles to preserve discoverability and brand control.

Coverage and methodology for .OPEN data

The downloadable file contains domain names from available sources, one per line in gzip-compressed plain text. It is a domain list, not a raw DNS zone file containing resource records, a WHOIS export, or a verified list of active websites.

Complete zone-file coverage. The .OPEN domain list covers every domain name present in the complete zone-file snapshot. Registered domains absent from the zone file are not included, and presence in the zone does not confirm a working website.

Additions and removals describe observed changes between dataset observations, not confirmed registrations or expirations; source changes and gaps can also affect counts. The coverage label describes the current dataset and does not establish comparable coverage across historical snapshots. Verify registration status separately before outreach, security decisions, or domain purchases.

The daily update target is 9 AM UTC. Use each file's snapshot date when scheduling imports or comparing archives; delivery can be affected by source delays. Historical availability varies by zone and date.

For reproducible analysis, record the zone, snapshot date, downloaded filename, and filtering rules. Usage is subject to our dataset license; enterprise and redistribution licensing is available separately.

.OPEN domain list questions

How many .OPEN domains are in the zone?

The .OPEN zone contains 1 domain names in the complete zone-file snapshot dated 02 Oct 2026. Registered domains absent from the zone file are excluded.

Is this a complete .OPEN domain list?

The .OPEN domain list covers every domain name present in the complete zone-file snapshot. Registered domains absent from the zone file are not included, and presence in the zone does not confirm a working website.

How do I download the .OPEN domain list?

Sign in with an account that has download access and use Download Domain List above, or automate the download with the API examples. Check plans and download limits before subscribing.

What format is the download?

A gzip-compressed plain-text file with one domain name per line. It contains domain names rather than DNS resource records, registration contact details, or website content.

Can I download historical .OPEN lists?

Available dates appear in the historical domain list table. Archive coverage varies, and downloads require historical access. See historical datasets for details.

Are removed domains expired or available to register?

Removal from an observed list does not establish expiration or availability. Check current registry or registrar information before attempting to register a name. The same limitation applies to expired / removed domain datasets.

When is the dataset updated?

All datasets have a daily update target of 9 AM UTC. Check the displayed snapshot date because source availability and delivery delays can affect individual files.
