What is .il.us TLD

.il.us is the state-designated second-level within the .us country-code namespace, serving Illinois public-sector and community entities. While not a standalone registry, many catalogs colloquially label it the .il.us TLD; we use that term to frame comparative analysis of .il.us domains and their operational footprint. In our global index, we currently observe 348 active records distributed across 3 countries, reflecting usage that includes mirrored or externally hosted assets. Of these, 59 resolve to live .il.us websites, indicating a cautious, institutionally focused namespace with limited churn. Together, these indicators suggest stability, predictable naming conventions, and strong alignment with government and education purposes. We provide category tags, lifecycle signals, and DNS telemetry for deeper auditing. Download webatla’s .il.us domain datasets now.

History and key features of .il.us TLD

Established within the .us locality hierarchy, .il.us organizes entities by geography and function rather than brand. The model supports municipalities, counties, school districts, and state-affiliated programs, producing consistent naming and long-lived records across .il.us domains. Typical structures reference locality or K–12 designations, with governance aligned to .us policy and registrar processes. Operationally, DNS adoption is measurable: 59 domains publish resolvable DNS, while growth remains subdued with 0 new registrations last week and 0 in December 2025. We observe steady availability among .il.us websites, alongside conservative change rates, which favors compliance, archiving, and continuity planning. Our datasets expose age, host diversity, MX posture, and TLS adoption to benchmark risk. Download longitudinal .il.us domain datasets from webatla to validate trends.

Why and who choose the .il.us domain

Organizations choose .il.us to signal Illinois jurisdiction, public mission, and administrative accountability. Primary adopters include municipal governments, county agencies, school districts, libraries, and regional authorities; some third parties participate where policy permits. For discoverability and trust, .il.us domains communicate clear geographic scope, while .il.us websites typically foreground civic services, compliance content, and community outreach. From our corpus, 59 live sites out of 348 active records suggest many hosts are informational, redirected, or offline but retained for governance continuity. Prospective registrants should assess naming alignment, eligibility, and DNS readiness, noting that operational visibility remains global across 3 countries. We surface peer cohorts and infrastructure fingerprints to support procurement and oversight. Download curated .il.us domain datasets from webatla.
