Newly registered .CASE domains per month
No new domains were added to the .CASE zone file in the 30 days to . Over the last 12 months, 4 new .CASE domains appeared.
Each monthly figure is the sum of daily additions: domain names in a day's zone file that were absent from the previous snapshot. A domain usually enters the zone file on the day it is registered, which is why these are treated as newly registered domains (NRDs); domains registered without nameservers are not in the zone file and are not counted.

Expired .CASE domains per month
In the 30 days to , 1 domains were removed from the .CASE zone file — about 0 per day. Over the last 12 months, 4 .CASE domains were removed.
Each monthly figure is the sum of daily removals: domain names in the previous snapshot that are missing from a day's zone file. Most removals are expired or deleted registrations, but a domain also leaves the zone file while it is on hold or loses its nameservers, and can return later. A removed domain is not necessarily available to register.

.CASE zone details
.case is a top‑level domain suited to websites that organize, present, or manage individual instances: legal cases, clinical case reports, product support tickets, case studies, portfolios, and incident logs. Organizations and professionals use it to make the site’s purpose explicit in the address, improving user expectations and navigation for audiences seeking case‑specific content.
As a branding choice, .case conveys specificity and functional clarity. It can reinforce trust for professional audiences by aligning the domain with the site’s content type, and it helps marketing and communications by creating concise, memorable addresses for campaigns, microsites, or client portals. Companies often select .case to separate case documentation or support resources from broader corporate websites.
When adopting .case, consider pairing the TLD with clear subdomains, keyword-rich second-level names, and consistent site structure so visitors immediately understand the site’s role. It is especially useful for legal firms, healthcare practitioners, product support teams, research groups, and consultancies. Also weigh availability, brand protection, and audience familiarity—some users may still expect primary brands on more common zones like .com.

Download and filter .CASE domains with the API
Download the latest .CASE domain list with your API token, then stream the compressed file through Python to find matching domain names. This example searches for cloud; replace the term to fit your research.
Requires curl, Python 3, and an API token with download access. Set ALLZF_API_TOKEN in your environment; plan limits apply.
# Download the latest .CASE domain list curl --fail --location \ -H "Authorization: Bearer ${ALLZF_API_TOKEN}" \ -o case.txt.gz \ https://allzonefiles.io/api/v1/zones/case/dl # Stream the file without loading it all into memory python3 - <<'PY'import gzip with gzip.open("case.txt.gz", "rt") as domains: for line in domains: domain = line.strip() if "cloud" in domain.lower(): print(domain)PY
Coverage and methodology for .CASE data
Complete zone-file coverage. The .CASE registry publishes its zone file through ICANN's Centralized Zone Data Service (CZDS). AllZonefiles.io downloads the complete .CASE zone file every day and extracts every domain name in it. Registered domains absent from the zone file, such as domains without nameservers or on hold, are not included, and presence in the zone does not confirm a working website.
Monthly totals. Each month's total is the domain count on the last available day of that month; the current month shows the latest snapshot.
New and expired domains. Each day's zone file is compared with the previous snapshot: names that appear are counted as new, names that disappear as removed. Monthly figures are sums of these daily counts, so a domain that leaves the zone and returns is counted again. The first month of data and the current month are partial and marked in the tables.
Freshness. 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.
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.

.CASE domain questions
How many .CASE domains are there?
The .CASE zone file dated 17 Oct 2026 contains 42 domain names. Registered domains without nameservers or on hold are not in the zone file, so the number of registrations can be slightly higher. Monthly totals since June 2025 are in the monthly table.
Is the .CASE zone growing?
In the 12 months to 17 Oct 2026, the .CASE zone kept the same size: a net change of 0 domains. Over the last 30 days the net change was -1.
How many new .CASE domains are registered each day?
No new domains were added to the .CASE zone file in the 30 days to 17 Oct 2026. In the last 12 months, 4 new domains appeared. Monthly figures are in the new domains table.
How many .CASE domains expire each month?
In the 30 days to 17 Oct 2026, 1 domains were removed from the .CASE zone file, about 0 per day. Most are expired or deleted registrations. Each month's count is in the expired domains table.
Is this a complete .CASE domain list?
Yes, for domains in the zone file. The list contains every domain name in the complete .CASE zone file published through ICANN CZDS. It does not include registered domains absent from the zone file, and presence in the zone does not confirm a working website.
How do I download the .CASE domain list?
Sign in with an account that has download access and use the download button above, or automate the download with the API example. Check plans and download limits before subscribing.
Can I download historical .CASE domain lists?
Yes. Available dates appear in the historical domain list table. Archive coverage varies, and downloads require historical access. See historical datasets for details.
Are expired .CASE domains available to register?
Not necessarily. A domain removed from the zone file may be in a redemption or pending-delete period, or on hold, and can return. Check current registry or registrar information before trying to register a name.
When is the .CASE data updated?
All datasets have a daily update target of 9:00 AM UTC. The latest .CASE snapshot is dated 17 Oct 2026; check the snapshot date because source delays can affect individual files.
