Recently, the Internet Corporation for Assigned Names and Numbers (ICANN) has approved the .XXX top-level domain (TLD) for domains. To register for a .XXX domain, you will need to prove that your company is associated with the adult industry. More information can be find here :

https://domains.icmregistry.com/faq.html

If your company isn’t related to the Adult industry but you want to protect your company’s brand and trademark. ICM does offer an option for domain owner from other TLD to reserve the domain and block others from registering. This help protect your company’s Brand and Trademark. (* There might be a fee for this )

To sign up and reserve your .xxx domains, you will need to sign up to the ICM site.

Once you have created an account, log in and start submitting domains to ICM.

There are two options currently.

1. Pre-Owned (Owners of domains from other TLD)

e.g. yourdomain.com or yourdomain.net

2. Wish List (domains that your want to have in the .xxx TLD)

e.g. yourdomain.xxx

Note: When entering ‘Pre-Owned’ domains, make sure to not include ‘http://’ and ‘www’ parts.
