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 — HTTP/3, United States — and adds company size and industry on top.

Reading the United States number

250,179 is the number of ranked websites in Hunter's index that were detected running HTTP/3 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 HTTP/3 worldwide for the full count, the technologies it turns up alongside, and every country Hunter ranks it in.
