A DPML – (Domains Protected Marks List) is a cost-effective way to block your brand trademarks from being registered at the second level across many New gTLD extensions.
DPMLs provide the essential service of protecting trademark holders against cybersquatting at a fraction of the cost of defensively, and individually, registering domain names across multiple TLDs.
The earlier a DPML block is registered, the more useful it will be. A DPML block does not retroactively rescind third party registration in any New gTLD that launched prior to a DPML registration (i.e., DPML subscribers will be able to block any names that have not already been registered in those TLDs).
Along with both registries, recommend securing/registering your place on the DPML as soon as possible, as many New gTLDs have already launched. Your goal is to ensure the most complete coverage across all New gTLDs.
