A list of United States domains is not a list of people.

Hunter turns each of those domains into named contacts with email addresses, and Discover takes the same two filters — CentOS, United States — and adds company size and industry on top.

Reading the United States number

1,477 is the number of ranked websites in Hunter's index that were detected running CentOS and carry a United States company address. It is a floor, not a vendor's customer list, and the address is where the business is registered rather than where the site is served from.

A detection describes what a site runs today, and a tag left in place after a team stopped paying still counts — so treat one detection as a lead to check rather than as a confirmed contract.

See CentOS worldwide for the full count, the technologies it turns up alongside, and every country Hunter ranks it in.

CentOS in the United States FAQs

Hunter keeps an index of websites, records the technologies detected on each one and the company address it holds for it. 1,477 of the sites running CentOS carry a United States address. The number is rebuilt daily.

No. The table lists the highest-ranked of them, and it leaves out any site Hunter holds no publishable contact data for. Discover searches the whole set.

No. It is the address Hunter holds for the company behind the site, so it is where the business is registered rather than where the site is served from.

Yes. Open a domain to see the email addresses Hunter holds for it, or take the same two filters into Discover and add company size and industry before you export.
