How many .observer domains are registered?
As of October 15, 2026, the .observer domain list contains 4,354 active .observer domains, 0.001% of all domains tracked by NetAPI, which makes .observer the #556 largest of 1,584 zones. 9 new .observer domains were registered in the last 24 hours and 283 over the last 30 days. Net of expired and deleted domains, the zone changed by +208 (+5.02%) in 30 days and by +1,406 (+47.7%) year over year.
The .observer domain list and the detailed dataset above are refreshed daily, so these figures move with the zone. 9 .observer domains are in the free NetAPI Top 1M. See the Top 1M list. 2 .observer domains are currently listed in the compromised domains feed (0.046% of the zone). See the TLD abuse report.
Frequently Asked Questions
See our FAQ for more answers.
Can I download sample datasets for the .observer zone?
Yes. Download a sample .observer domain list or a sample .observer dataset.
What is a basic domain list, and how does it differ from a detailed dataset?
Both cover the same 4,354 registered domain names in the .observer zone. A basic list is one domain name per line in a gzip CSV. A detailed dataset adds DNS servers, server IP, hostname, emails, phone numbers, and more. See the dataset format details.
What are active and new domains?
Datasets for .observer are updated daily. Active domains are all currently registered names in the zone. New domains are names added in the last 24 hours.
Can I download only newly registered .observer domains?
Yes. The New domains list contains only the .observer domains registered in the last 24 hours and is rebuilt every day.
To download it manually, sign in and click the number in the New domains column of the
download table on this page (the Download button next to it gets the full list of active domains).
Through the API, call
/api2/?method=download&zone_tld=observer&dataset_type=list&filter_type=new&token=YOUR_API_TOKEN
(dataset_type=dataset for the detailed dataset); see the API documentation.
Can I download deleted .observer domains?
Yes. The Deleted domains list contains the .observer domains that were in the zone the day before and have dropped out of it, so it covers the last 24 hours and is rebuilt every day. Deleted domains are available as a list of domain names only, there is no detailed dataset for them.
A deleted domain is not necessarily free to register. The list records names that have dropped out of the .observer zone: the registration expired, or the domain was suspended or undelegated. After the expiration date a domain normally goes through a renewal grace period and a redemption period, typically 30 to 75 days depending on the zone, during which the current holder can still restore it, and only after a short pending-delete period is it released for registration. Some names return to the zone when the holder renews or a suspension is lifted, and then appear in the New domains list again.
What format and size is the file?
Every .observer domain list and dataset is a CSV file compressed with gzip (.csv.gz):
the basic list has one domain name per line, the detailed dataset has one row per domain with the columns described in the
dataset format details.
Compressed, the current .observer basic list is about 20 KB and the detailed dataset about 97 KB.
Any archiver opens gzip files, for example the free
7-Zip on Windows,
and the API can also serve the files uncompressed (format=plain).
How do I automate daily downloads?
Schedule automatic downloads through the API. See the API documentation for authentication and endpoints.
Are emails and phone numbers available for every domain?
No. We collect contact details from public websites when available. Many domains have no published email or phone, and we do not guarantee these fields on every row. Do not use the data for unsolicited bulk outreach.
