I have a CentOS 6 x86 server. If I ping 220.127.116.11 and my server gateway, there's no problem. If I ping google.com, yahoo.com, etc, it returns "ping: unknown host google.com".
When I saw this problem, first thing I go to check is the /etc/resolv.conf file, but this file seems no problem. Where else should I check?
nameserver 18.104.22.168 nameserver 22.214.171.124
