How many .com domains are registered nowadays?

According to Verisign’s Domain Name Industry Brief of Q3 2022, there are 160.9 million .com domain names registered in the world, out of a total of 349.9 million registered domains across all top-level domains (TLDs).

The 100 million .com domain names milestone was surpassed during Q1 2012, about 27 years after the registration of the very first one — as reported by Verisign on The Domain Name Industry Brief of July 2012.

Top-level domain .com

The .com domain is one of the top-level domains in the Internet’s Domain Name System (DNS). It is derived from the word commercial, as it was intended for domains registered by commercial organizations. However, it later became a domain for general purposes and the most commonly used one as well.

The domains .com, .edu, .gov, .int, .mil, .net and .org were the first TLDs added in the DNS implementation at the beginning of 1985.
