.ai domains and subdomains
The GetDomainLists release contains 934,888 registrable .ai domains and 2,301,770 subdomains under them — names only, as historical observations, not a list of live websites.
The subdomain file has 2.5 .ai names for each registrable .ai domain in the domain file, against 3.4 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 (739,942 names, 32.1% of .ai subdomains).

Getting only .ai
The release is sold as two complete files covering every TLD in it, not as per-TLD lists. To keep only .ai, filter the files you download, for example:
zgrep -E '\.ai$' getdomainlists-2026-09-28-domains.txt.gz > ai-domains.txt zgrep -E '\.ai$' getdomainlists-2026-09-28-subdomains.txt.gz > ai-subdomains.txt
Try the format first with a free sample of 1,000 .ai domains (plain text, no sign-up). Both full files are $9 once, with 30 days to download.
Limits
- Historical observations collected up to this release (updated 28 September 2026); not proof that a name is registered, resolves or hosts a website today.
- Coverage is incomplete and uneven; these counts describe this release, not the whole .ai namespace.
- Names only: no owner, contact, hosting or registration-date data.
