.online domain list
There are 2,932,065 registrable .online domain names in our data, with 4,789,555 subdomains under them, in the release updated 16 October 2026 — names only, as historical observations, not proof that a name resolves or is in use today.
The subdomain file has 1.6 .online names for each registrable .online domain in the domain file, against 4.0 across all top-level domains. This is a ratio of file rows, not a typical count for one site: many domains have no subdomains in the file. The most common tracked leftmost label is www (1,959,078 names, 40.9% of .online subdomains).

Getting only .online
The release is sold as two complete files covering every TLD in it, not as per-TLD lists. To keep only .online, filter the files you download, for example:
zgrep -E '\.online$' getdomainlists-2026-10-16-domains.txt.gz > online-domains.txt zgrep -E '\.online$' getdomainlists-2026-10-16-subdomains.txt.gz > online-subdomains.txt
Try the format first with the free 1,000-name samples. Both full files are $9 once, with 30 days to download.
Limits
- Historical observations collected up to this release (updated 16 October 2026); not proof that a name is registered, resolves or is in use today.
- Coverage is incomplete and uneven; these counts describe this release, not the whole .online namespace.
- Names only: no owner, contact, hosting or registration-date data.
