What Is the .alstom Domain? Alstom's Brand TLD Explained

The .alstom domain is a closed brand top-level domain operated by Alstom, the French multinational rail transport group. It is not a public extension: unlike .com or .io, you cannot register a .alstom name for your own project, because the entire namespace belongs to one company.

If you searched for the ".alstom domain" hoping to buy one, the short answer is that you can't — but this page explains exactly what .alstom is, who controls it, why a company runs its own TLD, and what you can register instead.

.alstom at a glance

What is .alstom?

.alstom is a generic top-level domain that ICANN delegated to Alstom, a French multinational active in rail transport — trains, signalling systems, and rail infrastructure. The string is simply the company's own brand name.

.alstom is a brand TLD, often called a "dot-brand," not an open extension anyone can buy into. Alstom applied for the string so that it, and only it, would control every domain ending in .alstom. You can confirm the delegation and operator on the authoritative IANA root-zone record for .alstom.

History of .alstom

The .alstom string was delegated to the DNS root zone on December 4, 2015, following an application under ICANN's New gTLD Program. CORE Association handled the technical registry operation on Alstom's behalf. Its registry agreement includes Specification 13, the contract clause that formally designates a TLD as a brand and lets the operator keep it closed.

The record has remained active since delegation, unlike several brand TLDs that were later handed back and removed from the root.

Is .alstom available to register?

No. .alstom is a closed brand TLD, so there is no open registration and no registrar — including Namefi — can sell you a .alstom name. Registrations are limited to Alstom and organizations it authorizes, such as subsidiaries or partners. This is by design: a dot-brand exists precisely so the trademark holder controls the whole namespace and no one else can register a confusing or malicious lookalike.

If you have a genuine business relationship with Alstom and a legitimate need for a .alstom address, that request would go through Alstom's own corporate channels, not a commercial registrar.

How Alstom uses .alstom

Brand TLDs give a company a private space to organize its web presence. Typical uses for a dot-brand like .alstom include:

• Product and division sites on clean, memorable addresses tied directly to the brand.
• Campaign and event pages that are obviously official because only the company can create them.
• Internal tools and portals where a branded suffix signals a trusted, first-party destination.

Who it's not for: anyone outside Alstom. Because the namespace is closed, there is no scenario in which an independent developer, supplier, or business can build on .alstom.

Notable sites using .alstom

There are no third-party sites on .alstom, and there never will be while it stays a closed brand TLD — every .alstom address is controlled by Alstom. The company's main public presence runs from alstom.com, and it uses the brand TLD selectively rather than as a wholesale replacement. Rather than point to a specific address that may change, the honest description is simple: .alstom is Alstom's private namespace, used only for the company's own properties.

What is a dot-brand TLD?

A dot-brand (or brand TLD) is a top-level domain that a single company owns and operates for its exclusive use, secured through ICANN's New gTLD Program. Hundreds were delegated during the same application round, and they share a few defining traits:

• Closed registration. Only the brand and its affiliates can hold names.
• Specification 13. A registry-agreement addendum that formally recognizes the TLD as a brand and relaxes some rules that apply to open generics.
• Security and control. The brand eliminates the risk of anyone else registering a .alstom lookalike, which strengthens resistance to phishing and impersonation.

Some brands invest heavily in their TLD; others register it defensively and barely use it. A number of companies have even terminated their dot-brands after deciding the upkeep was not worth it.

.alstom vs open domain alternatives

If your goal was a short, brandable name rather than the .alstom string specifically, an open extension is the right tool. Here is how a closed brand TLD compares with domains you can actually register:

For your own venture, a matching .com remains the safest default; .io suits technical products; and .xyz is a flexible, low-cost modern option.

Reputation and trust

Ironically, the closed nature of .alstom is exactly what makes it trustworthy: because only Alstom can create these addresses, a .alstom link is verifiably official, which is why brand TLDs are considered strong against impersonation and email spoofing. That trust, however, benefits Alstom alone — it does not transfer to any name you might register, since you cannot register one. For your own project, deliverability and reputation will come from a well-configured domain on an open extension, not from a brand TLD you don't control.
