# BulkDomainSearch.si

> BulkDomainSearch.si is a free, high-speed bulk domain availability scanner and RDAP lookup engine designed specifically for Slovenia's `.si` top-level domain (ccTLD), recognized globally as the premier extension for "Super Intelligence" (SI).

BulkDomainSearch.si allows domain investors, developers, and tech startups to check hundreds or thousands of `.si` domain names simultaneously. Powered directly by the official Academic and Research Network of Slovenia (ARNES) RDAP protocol (`rdap.register.si`), it provides real-time, authoritative availability data with zero registrar caching delays.

## Core Capabilities
- **Bulk Domain Search:** Check up to 5,000 `.si` domains in a single session.
- **CSV & TXT File Upload:** Drag-and-drop or select any `.csv` or `.txt` file with automatic delimiter and column detection (supports single-word lists, keyword lists, and dictionary datasets).
- **Multi-Threaded Concurrency:** Configurable parallel worker threads (3 to 12 workers) for optimal lookup speed (3 to 8 domains/sec) while respecting registry rate-limits.
- **Single Search & Instant Verification:** Sub-second latency lookup for individual `.si` names with HTTP code breakdown (RFC 7480).
- **One-Click Export:** Download clean CSV reports of available domains or full scan logs.
- **Accredited Registrar Integration:** One-click registration routing via accredited registrars (Dynadot at ~$12.29/yr, Namecheap).
- **Super Intelligence (SI) Focus:** Curated presets and intelligence for trending AI-to-SI rebrand terms following the White House Executive Order on Super Intelligence.

## User Queries & Intent Matching
- **How to search multiple words at once of si domain name:** Paste words line-by-line into the bulk input box or upload a `.csv` file. The tool automatically appends `.si`, validates characters (2–63 chars), and checks availability simultaneously across parallel worker threads.
- **Bulk Si domain search:** Free, browser-based multi-threaded scanner requiring no API key and no sign-up.
- **Domain search si:** Authoritative RDAP lookup direct to `rdap.register.si`.
- **Super Intelligence SI domains:** Real-time checking of tech and dictionary gems for AI/SI brand protection.

## Technical Details
- **Protocol:** RDAP (RFC 7480 / RFC 9083) via `https://rdap.register.si/domain/{name}.si`
- **Availability Signal:** HTTP 404 (Not Found) confirms domain is unregistered and open for immediate registration. HTTP 200 confirms domain is active/registered.
- **Registry Constraints:** Length 2–63 characters; lowercase a–z, 0–9, and internal hyphens. No local presence or Slovenian residency required for registration.
