As much as we tend to associate the internet with youth, the Domain Name System, the technological architecture underpinning the internet, is itself no youngster, having recently celebrated its thirty-third birthday. The birth of the Domain Name System, or ‘DNS’ as it is commonly known, is traced back by many industry experts to June 1983, when Paul Mockapetris, an American computer scientist working at the University of Southern California’s Information Sciences Institute, first tested the system that revolutionise the budding internet and enable its exponential expansion.[1] Australia’s .au internet domain, one of the first domains created in the DNS, celebrated its thirtieth birthday in May this year.
