Some thoughts…

A general way to model next hop addresses is as an entity stack, entity/sub-entity/sub-sub-entity … .  I think the primary data for a next hop address would simply be an up/down flag.  A next hop would be down if any entity in its address was down.

The next hop logic could also accept a continuation to schedule when a next hop made a down to up transition.

If DNS lookup was done before next hop lookup, then next hop addresses would naturally be IP-address/IP-port .

If DNS lookup was done as a part of next hop lookup, then next hop addresses would naturally be hostname/IP-port .  (A down hostname would be one for which DNS lookup failed, or its IP address is down.)  A big disadvantage is that the results of the lookup would have to be provided by scheduling a continuation provided with the lookup request.  Another issue is if the DNS lookup results in a load-sharing/protection group of IP addresses.  If next hop lookup is going to handle that, it might make sense for it to handle strategies.
