How To Clear DNS Cache In Mac OSX & Speed up the browsing
Since last few days i have been facing the issues with the DNS lookups of few websites and have been using the Mac since last one week without any restart.
My Problem is: Websites are getting too much time in resolving DNS, ie taking too much time in opening. For example: Facebook.com is working fine but gmail is having trouble & delay.
After searching for a minute, I have discovered that this is the issue with the DNS so i have switched to open DNS ( Google: 220.127.116.11 & 18.104.22.168). This resolved my issue for a while but after few hours, i have started facing the similar slow connection issues though my internet connection have the 8MBps connectivity so i have switched the DNS to 22.214.171.124 & 126.96.36.199. Alas, it doesn’t completely resolved my issue so i have looked further and interrelate the problem with cache.
