.com domains and subdomains
The GetDomainLists release contains 102,673,226 registrable .com domains and 341,644,358 subdomains under them — names only, as historical observations, not a list of live websites.
The subdomain file has 3.3 .com names for each registrable .com 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. 17.6% of .com subdomain rows sit under a few shared namespaces (amazonaws.com: 56,227,361, amplifyapp.com: 2,692,871, herokuapp.com: 1,110,999); group rows by registrable domain before reading raw totals. The most common tracked leftmost label is www (71,325,990 names, 20.9% of .com subdomains).

Getting only .com
The release is sold as two complete files covering every TLD in it, not as per-TLD lists. To keep only .com, filter the files you download, for example:
zgrep -E '\.com$' getdomainlists-2026-09-28-domains.txt.gz > com-domains.txt zgrep -E '\.com$' getdomainlists-2026-09-28-subdomains.txt.gz > com-subdomains.txt
Try the format first with a free sample of 1,000 .com 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 .com namespace.
- Names only: no owner, contact, hosting or registration-date data.
