It's also possible the corrupt entries propagated to a local DNS in your computer (or other). In that case:
1. Power off all devices that connect to the modem.
2. Unplug the power to the modem from the wall socket.
3. After 60 seconds, re-plug the modem back in.
4. After another 60 seconds or so (once the modem has fully rebooted and all the lights are on) start powering up all of the devices attached to it.
