.ia.us domains list

What is .ia.us TLD

.ia.us is not a standalone global TLD; it is a state-level second‑level space within the United States country‑code TLD, designated for Iowa. In practice, .ia.us domains are typically allocated to public-sector and community entities with an Iowa nexus—municipalities, counties, K‑12 districts, and libraries—often implemented as third‑level structures (for example, city.ia.us, co.[county].ia.us, k12.ia.us, lib.ia.us). Within this locality framework, .ia.us websites signal geographic scope and public purpose, aligning with .US policy requirements and conventional naming. From an intelligence perspective, we monitor registration patterns, DNS configurations, and hosting footprints to map service delivery and institutional ownership across the namespace. Such structure aids discovery, reduces ambiguity, and supports long-term addressing for civic resources. Explore .ia.us domain datasets from webatla.

History and key features of .ia.us TLD

The .us locality hierarchy emerged to organize subnational digital identities under the ccTLD; .ia.us followed that model for Iowa. Most early .ia.us websites were municipal and county portals, with consistent third‑level labels to distinguish cities, counties, schools, and libraries. Over time, policy emphasis has remained on U.S. nexus, accurate registrant data, and appropriate public use, while technical features have broadly mirrored .US capabilities such as DNSSEC support and modern name server practices. Some government bodies have since adopted .gov, yet many .ia.us domains persist for legacy services, school districts, or community programs where continuity matters. We track lifecycles, delegation changes, and security posture to quantify risk and resilience within this space. Discover .ia.us domain datasets from webatla for deeper analysis.

Why and who choose the .ia.us domain

Organizations choose .ia.us when Iowa‑specific identity, public accountability, and predictable naming outweigh brand marketing needs. Primary adopters include city governments, county offices, K‑12 districts, libraries, and intergovernmental collaborations; commercial entities seldom use .ia.us domains unless supporting a public mandate. For users, .ia.us websites offer immediate geographic clarity and often reflect standardized information architectures, which can improve wayfinding and trust for local services. From an operations view, entrenched conventions and low switching costs make .ia.us suitable for long‑lived resources, intragovernmental workflows, or emergency communications where stability is key. We evaluate delegation hygiene, SSL adoption, and hosting centralization to surface dependencies and exposure across the namespace.
