Fresh CSC note examines top level domains popular with sizable corporations
Some top level domains punch above their weight for corporation registrations.
Corporate domain registrar and brand protection firm CSC has issued its Domain Name Trends 2026 note, examing which top level domain names are popular with sizable corporations. The firm included firms with 250+ employees and at least 100 domain names.
It’s an interesting look at the consumer market vs. corporate market for domain names. For example, these are the top five most registered domains by corporations:
- com
- net
- co.uk
- org
- info
This includes registrations for a primary website as well as defensive registrations. .Info might surprise some, but keep in mind it’s one of the older top level domains and was registered defensively by many firms. .Biz, which some would consider .info’s twin since of its release date, is #9 on the list.
The note also breaks down top TLDs by region. For EMEA firms, .co.uk moves up a spot to #2. .Fr and .de domains also move into the top five. .Com.au is #1 among APAC countries.
For North American firms, it’s probably what you’d expect: .com, .net, .org, .info, and .biz. These are widely considered the legacy top level domains. Still, sizable North American firms commonly register .co.uk, which is #6. As for .us…#7. It’s probably telling that North American firms are more likely to register a .uk domain than a .us domain.
None of the fresh top level domains from the 2012 round are among the top 20 registered by sizable corporations. When it comes to fresh TLDs, these are the five most registered:
- app
- online
- shop
- xyz
- sucks
CSC notes that many TLDs firms register, such as .cloud and .shop, are ripe for use in phishing attacks since they appear legitimate. Other top 20 names are reputation-senstive terms, such as .sucks, .porn, and .adult.
The note also notes that firms are behind the ball on .ai, with many brand-matching registrations held by third parties.
