Super intelligence, parked: what is on 144,786 new .si domains

After the US government renamed AI "super intelligence", Slovenia's .si more than doubled. Of 144,786 new .si domains, fewer than 5,000 show a website of their own. Most are parked or for sale.

Domain registrations · 30 October 2026

Slovenia's country code, .si, spent more than thirty years as a quiet national domain. Then the White House decided that artificial intelligence should be called super intelligence, SI for short, and .si became a cheap way to own a name that ends in it. We looked at what is actually on the new domains.

On 30 October 2026 we counted 144,786 .si domains that first appeared in our data from 18 September on and still exist in the DNS. 4,578 of them show a page with content of its own. Of the new domains with a website we could read, 84.7 per cent are parking pages. Among the .si domains we knew before September, the figure is 24.7 per cent.

Three dates and a registry chart

The registry, Register.si, publishes its daily registration count. Before the rush it recorded about a hundred new .si domains a day. The registry itself points to a post of 19 September in which President Trump offered alternative names for AI, among them "Superior Intelligence (SI)". On 22 September he told the UN General Assembly that the US would call the technology super intelligence, SI. On 29 September he signed Executive Order 14434, which tells federal agencies to write "Super Intelligence" and "SI" where they used to write "Artificial Intelligence" and "AI".

From 18 September to 27 October the registry counted 267,549 new .si domains. Its growth chart shows 190,719 .si domains for August and 465,335 on 30 October, almost two and a half times as many. The wave has passed its peak, but at around 2,500 a day the latest week still runs at twenty-five times the old normal. These registry figures are theirs, not ours; ours follow below.

What answers on the new domains

Even the 4,578 pages with content are not all what they seem. Judged by their titles, about a third of them offer the domain for sale or show a registrar's "registered with" page in the shape of a small website. Around one in six titles mentions AI, SI or intelligence. The redirects point the same way: most of the 38,398 new domains that forward elsewhere send the visitor to a domain marketplace. And a domain that cannot receive mail is rarely a domain somebody works with.

Parked on a handful of addresses

The older .si domains with an address are spread over 49,825 IP addresses. The new ones share 13,359. The ten largest IPv4 addresses carry 102,937 of the 138,798 new domains that have an address, 74 per cent, and those ten addresses belong to six services that park or sell domains.

Addresses that come in pairs answer for the same service, and a domain pointed at it lands on both. That is the shape a reverse IP lookup shows for speculation: not one owner with many domains, but many owners who have left their names with the same few sellers.

The names: short, without hyphens, taken everywhere else

An older .si name looks like a Slovenian business: longer, often with a hyphen, and in a quarter of cases not taken as .com. A new one is short and already exists almost everywhere else. That 87 per cent of the new names also exist as .ai sounds like a rush to copy .ai names, but .io is nearly as high and .com higher still. The buyers took names that are valuable in every extension and added the one extension that now reads as SI. Hardly any chose a name about intelligence: 1.5 per cent start or end in "ai". Hostinger, counting only its own customers, put the share of names with an AI term at 3.2 per cent in figures published on 9 October.

The clearest trace is in the shortest names. Of the 17,576 possible three-letter combinations, 7,843 were in use under .si before September. Since then 9,144 more have appeared, so at least 96.6 per cent of all three-letter .si names are now taken.

What it means

The rename produced a land grab, not a wave of new projects. Most of the new .si domains are stock: parked, priced and waiting for a buyer who wants an SI name. A few thousand are real websites. The .si that Slovenia uses every day, from the registry's operator arnes.si down, is still there underneath. The test comes when the first year runs out and every one of these names has to be renewed. Anyone who wants to follow that can watch the new .si domains arrive in the daily new-domain file.

How this was measured

New means a .si domain webXtrend found for the first time between 18 September and 30 October 2026; older means one we knew before 1 September 2026. Both groups count only domains that still exist in the DNS. We know 321,514 .si domains, 69 per cent of the registry's total, and the new group holds about half of the 267,549 domains the registry counted since 18 September; we cannot say whether the other half looks different. A few of the new ones may be older domains we only found now. Whether a domain has a website, forwards elsewhere or can receive mail comes from our crawl of the public domain name space; what kind of page it shows, from the start page we fetched. 52,941 older .si websites showed our crawler a bot check instead of a page, against 1,258 new ones; they are left out of the share of readable websites, so the content share of the older domains is a lower bound. Addresses come from domains_reverse_ip_current, the index of addresses each domain resolves to right now. The services were identified by the page a sample domain served on 30 October 2026, for Team Internet and Sedo by the owner of the network. The registry figures are Register.si's own, read from register.si on 30 October 2026. The figures are a snapshot of 30 October 2026 and are not updated afterwards.

Figures come from webXtrend's own crawl of the public domain name space. Each one carries the date it was measured. The API gives access to the same data.
