g4n.net
Infrastructure companies name themselves in a recognisable register. Short, technical, slightly abstract, nothing that sounds like it came from a workshop with sticky notes.
G4N sits in that register. The letters read as gateway, grid or growth and as networks or nodes, and the four-as-for form gives them a structure instead of leaving three characters to be memorised cold.
The extension is not a compromise for a business of that kind. It is the word network, which is what the product routes, monitors or connects.
Underneath any particular reading, the asset is length. A three-character address fits a terminal prompt, a config file, an endpoint, a logo and an email domain without a single trade-off, and the pool at that length has been closed for decades.
The name is listed. Offers considered.
