We probably wouldn't have the internet as we know it now if it wasn't for the work of Paul Mockapetris in the 1980s. In the early days of distributed networks, scalability started becoming an issue as there were hundreds of servers connected with hundreds of IP addresses that would need to have been used to access the content served on these servers. Back in the day, one would use a directory of websites to IP addresses and punch in an IP to access the content. Paul Mockapetris's contribution to ARPANET essentially created the automated resolution of names to IP addresses today known as the Domain Name System, or DNS for short.
