Where they are registered
For the 47 with a registrar in WHOIS (82% of all). Brand-protection registrars mostly hold defensive registrations made by brands themselves, so a domain there is more likely the brand's own than an imitation.

|---|---|---|---|
| GoDaddy | 10 | 21.3% | Retail |
| Namecheap | 3 | 6.4% | Retail |
