Clear browser dns cache

As you probably know Google Chrome has its own internal DNS cache. Need to both clear the host cache and flush the socket pools to get Chrome to refresh the DNS cache:

1. Navigate to [chrome://net-internals/#dns][1] and click "Clear Host Cache"
2. Navigate to [chrome://net-internals/#sockets][2] abd click "Flush Socket Pools"

Chrome dns cache issues

Built-in DNS uses the wrong DNS server "Internal DNS client enabled" is a problem with VPN or local cache servers

so to fix this problem, i just remove '8.8.8.8' from my DNS list
