DOMAIN EXTENSION GUIDE

.sys Domain Names

Not yet delegated

The.sys string is a proposed generic top-level domain with a strong technical feel, suggesting systems, infrastructure, software and connected services. Publicly announced information identifies Link Freedom Group and Starlight Registry (Namecheap) as separate public claimants associated with.sys in the 2026 ICANN new gTLD round, making it a contested string at the application stage rather than an active live extension. ICANN’s 2026 round ran from 30 April to 12 August 2026, and ICANN’s application materials explain that successful applicants still require a registry agreement before any delegation to the root zone.
