International domain names or addresses that can be written in non-English characters are expected to be approved this week.

This will spark one of the biggest changes to the internet in its four-decade history.

The Internet Corporation for Assigned Names and Numbers, or ICANN – the non-profit group that oversees domain names – is holding a meeting this week in Seoul.

The ICANN board will decide if will allow entire internet addresses to be in scripts that are not based on Latin letters.
