What DNS taught us about organisational naming, and why ENS is following the same path

When DNS was introduced in 1983, it was framed as a technical convenience. The internet was growing, the host file approach was starting to break down, and a naming system was needed to translate human-readable names into machine addresses at scale.
That is how DNS was designed. It is not how it ended up being used.
The interesting part of DNS was not just the protocol. It was what organisations did with it once they realised they had a structured naming system at their disposal.
Within a few years, companies stopped treating a domain as just the place where a website lived and started using it as the root of an identity hierarchy. Sales, engineering, support, corporate, and internal tools all got their own subdomain. Production, staging, and development environments were separated by name. Regional deployments were organised by geography. Service names started mapping to functions rather than machines.
By the late 1990s, no serious organisation operated without a structured DNS namespace. By the mid-2000s, the namespace had become almost invisible because it was so fundamental to how companies operated.
