What's the point of having www.? Isn't it just useless extra text? Since everyone is used to it, www.google.com looks more well-balanced than google.com, but why did it start in the first place?
One thing I noticed, is that google.com has the IP of 74.125.53.100, in the UK, while www.google.com has the IP of 209.85.135.106, in the US. Could anyone explain a bit on that?
Edit: Is example.tld supposed to be a different machine than www.example.tld? Does it have to be?
