On 10 December 2021, researchers disclosed Log4Shell, a critical vulnerability in Log4j, the ubiquitous Java logging library. The article documents IP Twins' immediate assessment, offering registrar clients transparency: the core systems — Domainarium 2, the EPP tools and the DNS architecture — contain no Java and are therefore not exposed. Only two resources use Java: the third-party database supporting domain name registration monitoring, and the VMware solutions supplied by hosting partner OVH for private cloud management; both sit behind strict IP whitelisting, reachable only from IP Twins' internal addresses, which forecloses external exploitation. After full technical verification, the company confirmed that neither its registrar services nor its nameservers were at risk, and invited clients to contact support with any questions. A model of the prompt, factual communication expected from infrastructure providers when a major vulnerability breaks.
