Background: 互联网创始人伦纳德·克兰罗克教授在互联网四十周年庆祝演讲中说，他当初从未料想过这一网络系统会出现黑暗的一面。他说，初期的互联网是在一种相互信任的文化中运作的。

Forty years ago, a team of engineers sent a message from a computer in Los Angeles to a terminal in Palo Alto.

It was supposed to read "login". But only the first two letters arrived.

Nevertheless, it was the first time computers talked to each other.

Now, the man who led that experiment, Professor Leonard Kleinrock, says the internet has since developed a dark or negative side such as viruses and identity theft.

He says he and his team should have installed better protection for web users all those years ago.

Now, the internet is expected to take a huge leap forward.

The internet regulator that controls the world's web addresses is likely to approve domain¹ names that go beyond the existing Latin-based ones.
