3. Zone Details: .cba

The .cba namespace is well suited for organizations and initiatives that identify strongly with the CBA acronym. Typical use cases include trade associations, regional banking cooperatives, professional certifications, consulting practices, and community or cultural groups that want an acronym-driven domain to match their name or brand shorthand.

Choosing .cba can help projects signal concise, professional branding and make long names more memorable online. It is often selected when more common extensions are unavailable or when an organization wants a distinct acronym-based presence. Organizations should weigh audience familiarity—some users default to .com—and consider coordinating trademark and social profiles to maintain brand clarity.

From a practical perspective, registrants should treat .cba like any other gTLD: plan a consistent naming strategy, register common variants to prevent confusion, configure email and DNS securely, and ensure compliance with any registration requirements. The extension works best when it reinforces existing branding or clearly communicates an acronym-based identity to a targeted audience.

Coverage and methodology for .CBA 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 .CBA 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.

Use .CBA domain data in your workflow

Monitor brands and threats

.CBA domain list questions

How many .CBA domains are in the zone?

The .CBA zone contains 84 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 .CBA domain list?

The .CBA 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 .CBA 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 .CBA 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.
