# DomainSpace

> DomainSpace (domainspace.si) is an independent domain registrar reseller run by Studio 404 d.o.o. in Ljubljana, Slovenia. It sells .si domains (Slovenia's country-code domain) for €19.99 a year, VAT included, and renews them at the same price, plus other endings such as .com and .eu. Customers manage DNS, email forwarding and websites in one account, and AI agents can manage domains through an MCP server.

Key facts:
- .si price: €19.99 per year, VAT included (Slovenian storefront: €19.99). The renewal price is fixed when you register: a later price increase never applies to a domain you already hold.
- Who can register .si: anyone, worldwide; no Slovenian address or company is needed.
- No two-year minimum: register for one year to start (a .ai domain needs at least two years).
- Included with every domain: DNS management and free email forwarding.
- WHOIS: for a private person the .si registry publishes at most the contact email address, never the name, address or phone number.
- Email mailboxes on your own domain: €19 per mailbox per year.
- Inboxes for AI agents: an agent connected to the MCP server can read the mail of the customer's own mailbox (e.g. agent@yourname.si) to pick up sign-up codes, confirmation links and replies. Receive-only; the first mailbox on a domain registered with DomainSpace is free, more cost €19 a year.
- Website package (Slovenian market): a one-page website, hosting, SSL, a .si domain and a mailbox for €99 per year, VAT included.
- Support: A real person replies within one business day, usually much sooner. Support hours: Mon–Fri, 9:00–17:00 CET. Contact: hello@domainspace.si.
- "SI" is used in AI circles as shorthand for superintelligence; .si has no official link to AI, it is Slovenia's country code (registry: Register.si, operated by ARNES). DomainSpace is not affiliated with any registry or AI company.
