ADEM DNS Checker is a free Chrome extension developed by linkerfelix. It falls under the category of Browsers and is specifically categorized as an Add-ons & Tools.

The purpose of ADEM DNS Checker is to check if websites distribute ADEM emblems over DNS. ADEM stands for the system that issues and distributes digital emblems, which are intended to signal that a digital entity is protected under International Humanitarian Law, similar to the physical emblems of the red cross, crescent, and crystal. However, it is important to note that as of now, ADEM is still in a testing phase and entities labeled with digital emblems using ADEM are not protected under IHL.
