[QUOTE=Rbw88;2410683]I've heard if you change your DNS setting you can loose a bunch of stuff on your computer so I have been afraid to do it.[/QUOTE]You won't lose anything, DNS is a way to change IP addresses into Domain names.
When internet started, to go to a webpage you needed to know the IP address, this is sort of like a phone number.
People would have to keep a list of websites and what there IP address was.
As the internet grew, there were many numbers to have to remember. So DNS was made.
So for example.
Google IP address is [URL]http://74.125.224.72/[/URL].
And facebook is [URL]http://69.63.176.13/[/URL].
And this would be difficult to remember all these numbers, you can not just type facebook in your web browser, then the IP address of facebook is requested.
From the DNS server, the DNS server says this site facebook IP address is 69.63. 176.13, and you go there. Sites you go to alot, will store DNS info in your computer, so you do not have to keep requesting the same info, what is IP address of facebook. This is saved in your DNS cache, sometimes you need to clear that, with ipconfig / flushdns, cmd.
In conclusion, DNS is just a way to make a IP address of numbers into a name you can remember and understand.
DNS is how domain names are translated into IP addresses, and DNS also controls email delivery. DNS is what allows you to use your web browser to find web sites as well as send and receive email.
DNS makes it possible for us to use easy to remember domain names in place of complex IP addresses ([URL]gracechurch.com[/URL] instead of 209.61. 148.168).
DNS is sort of like the white pages directory of the internet. When you enter a domain name into your internet browser, DNS does the directory lookup to find out which server that domain is pointed to and what it's IP address is and then it responds by displaying the site you requested.
