I'm wondering if it makes sense to provide a default implementation for the new method. It's unlikely we'll be adding a new endpoint type anytime soon but failing to distinguish between "look up the addresses again" and "give me the addresses you got last time you looked them up" is what got us into this situation in the first place. I kinda feel like having this as a default might lend itself to landing back in exactly that situation.

Nit: save yourself the method call overhead here and just return address directly... ?

Is there a particular reason to jump through the splitting/to Int/toArray ops here rather than just using InetAddress.getByName()? I don't think it does a reverse lookup if you just give it a string containing an IP address but I could be wrong.

Sorry, I am confused. Could you pls explain more?
InetAddress.getByAddress does not do reverse lookup. InetAddress.getByName will look it up. We don't want it to look up. Therefore, I think InetAddress.getByAddress is the one we should use. :)

Don't we want to cache the last value returned by resolve() and return that here instead?
