e2k.net
The K is the useful character here. In technical shorthand it routinely means kilo, Kubernetes, knowledge, or thousand, which hands the name several credible readings rather than leaving it arbitrary.
Edge to Kubernetes describes an architecture problem infrastructure companies are actively selling into. Energy to kilowatt fits power systems. Experience to knowledge fits learning and research platforms. Each is a defensible position for a buyer wanting the name to mean something specific.
If none applies, the letters remain letters, and a three-character domain with no baggage holds its value on scarcity alone. The pool closed decades ago and the only movement in it is names leaving.
The .net is right for technical infrastructure, where it reads as native rather than second choice.
