.mil domains list

What is .mil TLD

The .mil top-level domain is a restricted namespace dedicated to official U.S. military organizations and supporting commands. Within .mil domains, governance and eligibility are tightly controlled to safeguard operational integrity; .mil websites are therefore expected to represent authoritative, mission-critical communications. We index the namespace globally and currently measure 117 active records, including 117 live hosts and 117 domains resolving via DNS. Usage is concentrated in 2 country, reflecting its specialized scope rather than general commercial adoption. This focus means analysts can map command structures, hosting footprints, and change cadence across .mil domains and .mil websites with high signal-to-noise.

History and key features of .mil TLD

Launched in the 1980s as one of the earliest sponsored TLDs, .mil was designed around continuity, authentication, and controlled delegation. Over time, .mil domains have adopted standard protocols and security practices, while .mil websites typically operate within hardened networks and defense-grade policies. The namespace remains centralized, with eligibility limited to designated military entities; public registrations are not permitted. Our telemetry shows consolidated geography: 2 country uses the TLD, aligning with its U.S.-centric mandate, and 117 domains maintain DNS records, indicating stable, operational infrastructure. These characteristics make the zone a useful barometer for organizational structure and operational posture across .mil domains and .mil websites.

Why and who choose the .mil domain

Entities choose .mil domains to signal verified affiliation with U.S. military components and to benefit from centralized governance, standardized naming, and strict eligibility checks. Typical registrants include branches, unified commands, programs, and installations; .mil websites often expose public affairs content while segregating sensitive systems. Adoption is intentionally finite: we observe 117 active domains with 117 live sites, and expansion is minimal – new registrations last week were 0, while registrations last month were 2 in December 2025. Concentration in 2 country underscores a specialized mission rather than broad market growth across .mil domains and .mil websites.
