Editor don't accept ext eg. ".info" - Accept ".inf" but DNS don't accept that.

You are right, the DNS does not accept it because you might have to flush the DNS cache http://www.wikihow.com/Flush-DNS or edit the HOST file with another editor or this TLD is reserved.

 

For example the .dev TLD cannot be used any more since now there are offically .dev domains to buy and unless you have it in your HOSTS file as well as in your VirtualHost file it won't work and then it will also throw you errors. If you check the dnscache and get this it has to do with this info from icann.

Windows IP Configuration

    1.dev
    ----------------------------------------
    Record Name . . . . . : 1.dev
    Record Type . . . . . : 1
    Time To Live  . . . . : 3522
    Data Length . . . . . : 4
    Section . . . . . . . : Answer
    A (Host) Record . . . : 127.0.53.53

So this might also apply to your case trying to use the TLD .info.

 

Try flushing the DNS cache. Use HostsMan, it is free and available here: http://www.abelhadigital.com/hostsman
