-- If you created something that is used billions of times every day by millions of people, you might expect it to be around for a long time to come.
Yet Dr Paul Mockapetris, inventor of the net's Domain Name System (DNS), entertains few illusions about the longevity of his creation.
If ever your computer needs help finding out where a. com, .uk or any other website is on the net, the DNS is the system it consults for that address.
"I expect the DNS to be eventually replaced," he told the BBC News website.
"The internet is all perishable technology that going to get replaced or extended." --
