Machine-readable to human-readable

Peggy Karp (????)

In way-back olden times (the '60s) people had to keep track of internet servers by their machine-readable network addresses.

This wasn't a big problem since there were only a few servers. But as the network grew, people started keeping lists of each address with a more human-friendly name next to each one, so they could identify them more easily.

In 1971 Peggy Karp decided to standardise this process by keeping a single list that she kept up-to-date, and made available to everyone else to download and use.

As it was a mapping of host names to internet addresses she decided to call it HOSTS.TXT. This was the first example of an organised, shared registration process – which would later grow into the modern-day system of using snappy-sounding domain names to connect to numerical IP addresses.

So the next time you remember a website address, or register a domain name and configure it to point to a server address – think of Peggy Karp.
