So my 2wire with U-Verse kept going out on my mac and I needed to turn airport off then on again every couple of minutes. I read where if I put the numbers 220.127.116.11 and 18.104.22.168 in the DNS it would fix it and it did. I am clueless when it comes to DNS and want to know if they can somehow hack my computer or give me a virus by me changing this.
I know this sounds like a stupid question and if someone has time to explain DNS to me in SUPER layman's terms I would be very appreciative.

DNS is Domain Name System and it turns a hostname into a IP address without it instead of typing att.com you would need the IP address also
search engines would not work as we know it.

No one's going to hack your computer or give you viruses due to hard coding the DNS servers.
You're still behind the firewall of the RG. DNS takes the name of the website and turns it into
the IP address of that website. It's easier for us to remember and understand words and the
internet is built on IP addresses which would be hard to remember ie. 122.34.678.01.

The first clue that something is trying to get in your Mac would be a notification on the screen telling you this has an application needing your password and you did not download a particular app also a suspicious one would be you need their particular player to load a video or song
which there again needs your permission once this is given if the code is written corectly you just handed over control so be careful your Mac
came with the ability to play almost anything legal out there and the only other program you might need is Flip For Mac.

Thanks I appreciate the help. The internet seems faster since I changed the DNS.
You might want see this thread as it's about the problem you had:

The DNS - Domain Name System - is somewhat like Directory Assistance for the Internet.
To quote Homer Simpson: "Operator! Give me the number for 411!"
Well, in your case, two possible "numbers for 411" are 22.214.171.124 and 126.96.36.199. Those are the low-level Internet Protocol (IP) addresses for special "resolvers", run by AT&T (but named dnsr1.sbcglobal.net and dnsr2.sbcglobal.net) that take domain names like "www.att.com" and turn them into Internet addresses like 188.8.131.52.
You may already suspect that there are many more than two resolvers out there. And there are. Certain operating systems (e.g., Linux, BSD and Mac OSX) even give you the option to run your own so you don't have to depend on anyone else's.
Google has just announced free domain resolvers available at 184.108.40.206 and 220.127.116.11. They'll work just like the two from AT&T, so the only reasons to prefer one over another would be speed, reliability and security. Some web pages are built from so many pieces from so many different servers that the time spent resolving domain names into IP addresses can take up a significant fraction of the total load time. So your best bet, if you want to get into it, is to simply try them and see if some do work better for you.
