Default gateway configuration

I have a 1921 router plugging into Charter coax.  The routers Gi0/0 is being assigned a dynamic IP address to the outside.  My question is simply how should I route to the outside world when I do not know the IP of the gateway as it might change.

I was thinking of doing 

ip route 0.0.0.0 0.0.0.0 Gi0/0

When I type that in I get the following returned to me,  should I be alarmed?

%Default route without gateway, if not a point-to-point interface, may impact performance

Is there a better way to handle routing everything out an interface? Normally I would point to the next hop, but since the outside interface is dynamic the next hop could change periodically?
