Newly registered .CISCO domains per month
No new domains were added to the .CISCO zone file in the 30 days to . Over the last 12 months, 3 new .CISCO 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. Registration in .CISCO is restricted, so few new domains may appear.

Expired .CISCO domains per month
No domains were removed from the .CISCO zone file in the 30 days to .
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.

.CISCO zone details
The .cisco top-level domain is a brand-operated namespace managed by Cisco Systems for its official web properties. It is used to host product and service pages, support and documentation, developer portals, partner programs, and communications that require an unmistakable association with the Cisco brand.
Typical use cases include consolidated product microsites, secure download and support endpoints, partner and reseller portals, event and training platforms, and developer resources. Organizations and teams choose .cisco to make affiliations explicit, reduce ambiguity for end users, and present a consistent corporate identity across digital touchpoints.
As a restricted, brand-controlled TLD, .cisco provides Cisco and authorized partners with centralized namespace governance and policy control. That governance helps ensure predictable naming, alignment with corporate branding, and easier management of certificates and redirects, while functioning like any standard generic TLD in DNS and browser environments.

Download and filter .CISCO domains with the API
Download the latest .CISCO 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 .CISCO domain list curl --fail --location \ -H "Authorization: Bearer ${ALLZF_API_TOKEN}" \ -o cisco.txt.gz \ https://allzonefiles.io/api/v1/zones/cisco/dl # Stream the file without loading it all into memory python3 - <<'PY'import gzip with gzip.open("cisco.txt.gz", "rt") as domains: for line in domains: domain = line.strip() if "cloud" in domain.lower(): print(domain)PY
Coverage and methodology for .CISCO data
Complete zone-file coverage. The .CISCO registry publishes its zone file through ICANN's Centralized Zone Data Service (CZDS). AllZonefiles.io downloads the complete .CISCO 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.

.CISCO domain questions
How many .CISCO domains are there?
The .CISCO zone file dated 17 Oct 2026 contains 41 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 .CISCO zone growing?
In the 12 months to 17 Oct 2026, the .CISCO zone grew: a net change of +3 domains. Over the last 30 days the net change was 0.
How many new .CISCO domains are registered each day?
No new domains were added to the .CISCO zone file in the 30 days to 17 Oct 2026. In the last 12 months, 3 new domains appeared. Monthly figures are in the new domains table.
How many .CISCO domains expire each month?
No domains were removed from the .CISCO zone file in the 30 days to 17 Oct 2026. Each month's count is in the expired domains table.
Is this a complete .CISCO domain list?
Yes, for domains in the zone file. The list contains every domain name in the complete .CISCO 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 .CISCO 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 .CISCO 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 .CISCO 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 .CISCO data updated?
All datasets have a daily update target of 9:00 AM UTC. The latest .CISCO snapshot is dated 17 Oct 2026; check the snapshot date because source delays can affect individual files.
