.mo.us domains list

What is .mo.us TLD

.mo.us is a geographic second-level within the .us country-code namespace, associated with Missouri and typically used by public-sector and educational entities. In practice, .mo.us domains follow locality-oriented naming that supports clear jurisdictional identity across agencies and districts, while coexisting alongside .gov and other TLDs. From our index, we currently track 138 active .mo.us domains and 18 live .mo.us websites; 18 of those show resolvable DNS, indicating a compact but maintained footprint. This structure helps analysts map administrative ownership and legacy infrastructure at state and municipal levels. We present normalized metadata, DNS telemetry, and hosting fingerprints to benchmark resilience and change over time. Download webatla’s .mo.us domain datasets to explore this namespace.

History and key features of .mo.us TLD

The .mo.us TLD emerged from the locality-based delegation model used for .us, where states and municipalities could adopt hierarchical naming for government and school networks. Key features include geographic scoping, descriptive third-level labels, and continuity for legacy systems – factors that still shape .mo.us domains and many .mo.us websites. Our recent crawl shows registrations remain static: 0 new domains last week and 0 in November 2025, with signals detected across 3 countries of use. Such low churn suggests long-lived records, valuable for time‑series analysis of email, DNSSEC, and hosting changes. We annotate registrar, nameserver, and SSL attributes to track stewardship and risk posture. Get the complete .mo.us datasets from webatla for deeper analysis.

Why and who choose the .mo.us domain

Organizations that prioritize jurisdictional clarity, existing email estates, or regulatory alignment often choose .mo.us domains, while legacy .mo.us websites continue serving residents, students, and staff. Typical adopters include municipalities, counties, school districts, libraries, and inter-agency programs seeking stable, geographically anchored addresses. Evaluating this space benefits from baseline totals – 138 active domains versus 18 live websites – plus DNS evidence and uptime history. We correlate hosting, ASN, and certificate rotations to surface consolidation, shadow IT, and decommissioning patterns relevant to procurement and security teams. These insights guide modernization roadmaps without losing continuity for public services and records. Download webatla .mo.us domain data and benchmark your public-sector footprint.
