      Hello,

      Many ISPs provide CPE routers configured with a static IP, so that pinging your default gateway wouldn't show if your connection was down or not.

      What are the best IPs to use for monitoring a connection?

        It varies by region, but something a few hops out from your ISP is good. An anycasted IP such as 8.8.8.8 or 8.8.4.4 is good in many parts of the world.

          Ok.

          So if you had a situation where you were using Google DNS for DNS resolution also, you would configure it this way (to avoid routing conflicts)?

          ISP1 gateway - monitor IP 8.8.8.8
          ISP2 gateway - monitor IP 8.8.4.4

          DNS servers:

          8.8.8.8, gateway ISP1
          8.8.4.4, gateway ISP2
