How do i disable OpenDNS COMPLETELY?

[Ryan]

so, i "accidentally" change my DNS to 208.67.220. 220 and 208.67.222. 222 because i usually use goggle dns and this online game i'm playing somehow have problem with google dns and recommend players to use this dns

but then when i browse the internet, i can't get to a lot of website (even facebook)

i've tried clearing my cache for today, i have changed my DNS back to google's, i also use dynamic IP (it's changing everytime i connect)

can you please provide a step by step guide on how to disable this service

Try 129.250.35.250, which is an ntt.net DNS server.  Visit the site below for a (very incomplete) list.

After changing the server address, open an elevated command prompt, then type
    IPCONFIG /FLUSHDNS
and press Enter to clear the stored DNS lookups.
