I'm setting up a new firewall with a main and backup Internet connection. I need to ping a couple of addresses from the each interface to validate that they are up and able to route traffic.

In the past I have used things like a my next hop router and something like google.com and  DNS servers etc.

What's your pick for a couple of IP's that if either works I can assume the circuit is alive and passing traffic?
