.sd.us domains list

What is .sd.us TLD

.sd.us is a geographic second‑level within the United States country‑code TLD (.us), aligned with South Dakota’s public sector and community institutions. In practice, .sd.us domains and .sd.us websites serve civic, educational, and local administrative needs where clear geographic provenance matters. Typical use includes cities, counties, school districts, libraries, and delegated public programs. As a domain intelligence platform, we monitor registrations, hosting, and DNS activity to quantify this footprint. Our index currently shows 34 active registrations, of which 8 resolve as live .sd.us websites and 8 publish DNS records; observed presence spans 2 countries due to hosting and CDN distribution. This suggests a compact, stable namespace with limited churn and predictable behavior. Download .sd.us domain datasets from webatla.

History and key features of .sd.us TLD

The .us locality framework introduced state‑based second‑level spaces like .sd.us to standardize addressing for government and K‑12 entities. While precise delegation milestones vary by locality, .sd.us follows .US policy conventions: geographic sub‑labels (e.g., city.sd.us), institutional qualifiers (e.g., k12), and conservative naming aligned to public interest. For researchers of .sd.us domains and auditors of .sd.us websites, the namespace exhibits low growth and a predictable structure suitable for compliance monitoring. We detect 0 new registrations last week and 0 in January 2026, reinforcing minimal expansion; operationally, 8 show active DNS, indicating maintained – but limited – infrastructure. These characteristics yield a relatively stable dataset for longitudinal analysis of public‑sector digital presence. Download the complete .sd.us dataset from webatla today.

Why and who choose the .sd.us domain

Organizations adopt .sd.us to communicate South Dakota provenance, regulatory alignment, and a public‑service mission. Primary adopters include state agencies, county and municipal offices, K‑12 districts, and libraries; mission‑aligned nonprofits also appear. For stakeholders comparing namespaces, .sd.us domains emphasize locality and accountability, while .sd.us websites prioritize clarity over broad branding. Based on our measurements, the space remains compact: 34 active records, with 8 measurable .sd.us websites, distributed across 2 countries via hosting arrangements. This scale reduces namespace collisions and aids trust signals, though it may limit cross‑jurisdictional marketing. We recommend .sd.us where auditability, locality signaling, and stable governance outweigh expansion ambitions. Download webatla’s .sd.us domain intelligence dataset now.
