The Domain Naming System, DNS, is one of the Internet's most important components.
It pairs the easy-to-remember web addresses with their relevant servers. Without DNS, one would only be able to access websites by typing in its IP address, a series of numbers such as "194.66.82.10".
More by circumstance than intention, the US has always had ultimate say over how the DNS is controlled - but not for much longer, the BBC reported today.
The terms of the change were agreed upon in 2014, but it wasn not until now that the US said it was finally satisfied that Icann was ready to make the change.

Users of the web will not notice any difference because ICANN has essentially being doing the job for years.
But it's a move that has been fiercely criticised by some US politicians as opening the door to the likes of China and Russia to meddle with a system that has always been "protected" by the US.
ICANN was created in 1998 to take over the task of assigning web addresses. Until that point, that job was handled by one man - Jon Postel. He was known to many as the "god of the internet", a nod to his power over the internet, as well as his research work in creating some of the systems that underpin networking.
Postel, who died not long after ICANN was created, was in charge of the Internet Assigned Numbers Authority (IANA).
It is that final detail that is set to change from October 1. No longer will the US government - through the NTIA - be able to intervene on matters around internet naming.
From October, the "new" ICANN will become an organisation that answers to multiple stakeholders who want a say over the internet. Those stakeholders include countries, businesses and groups offering technical expertise.
"It marks a transition from an internet effectively governed by one nation to a multi-stakeholder governed internet: a properly global solution for what has become a global asset," he added.
