Reconfigure DNS settings

1 Change each device

On a Mac, go to Apple > System Prefs > network > Advanced > DnS tab. On iPad or iPhone, go to Settings > Wi–Fi and tap the “i” next to the connected network. Scroll down and tap configure DnS.

2 Set network–wide

log in to your router’s configuration utility, and check its DHcP settings for options to set primary and secondary DnS servers. This changes the DnS for connected devices that use DHcP.
