Why would we want to use a different DNS? I'm fine with my ISP's DNS servers.

 

Also, your title is misleading. To flush the DNS, you go into an elevated command pompt, and you enter the command "flushdns" without the quotation marks.

Well, some ISPs have odd configuration issues with their DNS servers which can only be avoided by switching to a different provider, like from my previous experience AT&T's DNS servers have the times for them holding entries being excessively long (As in it will take upwards of 24 hours for it to register a change in IP address for the site), or Time Warner redirects requests to nonexistant addresses to a bing search, or another DNS provider I have used would occasionally get corrupted entries preventing the use of their servers for looking up specific webpages.

Sbrideau, wyvren2000 said exactly what I was going to say. I heard a lot of people were having an issue connecting to a website that just changed. This has helped fixed many peoples issues, and I made this guide for noobs who couldn't do it there self :)

Google's are easier to remember so when I need to test with one that isn't my ISP's (which are easy to remember since I work on them occassionally :) ) I just use them.

I don't think 24 hours is an excessively long time for DNS, it is actually pretty standard. The redirect to their own search is the main reason I didn't use my ISP's DNS when I was on Cincinnati Bell, and why I don't like OpenDNS either.

Ah, I see, I had never heard of issues with DNS before (other than the issues on the computer itself). Guess there is a first with everything.

Or just go into command prompt and type ipconfig/flushdns..

Really? Cause as I recall it was you who was the one cussing me at base. Also, re-read what you just said: one 15 second delay (which is an exaggeration to begin with) ruins floor times? You are beyond ridiculous.

You also don't need to signup to OpenDNS at all to use it making most of your steps unnecessary, you just simply need to configure your OS/Router to use their IP addresses.

 

Also you can use Google Public DNS or Level3 DNS both of which have easier to remember IP addresses.

Although it would be helpful to post a link to at least Google's config instructions; I just did that and I think it fixed my problem with my slow internet connection. Or it at least made me think it's faster now. Tbh before I saw this topic I had no idea about this but it's really helpful.
