AdultBlock and AdultBlock+


  • Overview
  • Eligibility
  • API Documentation


XXX Sunrise B blocks (or short SRBs) which prevent domain registrations matching to trademarks under the .XXX TLD will expire on 1st December 2021. This could expose brand owners to domain abuse if they do not convert expiring SRBs to either an AdultBlock or AdultBlock+ product.

Per default, SRBs in our Hexonet backend expire automatically - contrary to the handling at the Registry. That means, instead of having to opt-out of having your SRB converted, you only opt-in for those that you wish to be converted. So you don’t run the risk of having to pay for something you don’t want to buy.

The AdultBlock and AdultBlock+ products are the new rights protection blocking services provided by the ICM Registry specifically for brand holders.

AdultBlock: allows you to block domain registrations with exact match terms across four adult themed TLDs: .ADULT, .PORN, .SEX and .XXX.

AdultBlock+: allows you to block domain registrations with exact match terms and its variants (example: duplicate characters, missing characters or misspelling) across four adult themed TLDs: .ADULT, .PORN, .SEX and .XXX. The level of protection is increased with this option; it adds the ability to block all variants that are confusingly similar to the trademarked term.

Please note that this fee is non-refundable, and there is no grace period.

ICM offers a tool to query all protected variants for a given trademark at:
