I can't open specific websites on my Mac
From the past few days, I am not able to open some websites such as pinterest.com, Moz.com, Techquintal.com,Cnet.com, etc. on my Mac. Please help me how can I solve this? It is showing some DNS errors in the browser. All other checked sites are working fine without any problems.
