As a baseline strategy, you should do DNS lookups every time and rely on the caching DNS server on your box to manage the cached information. (That's what the C++ components do.) There are circumstances where the baseline strategy doesn't work well enough. We are thinking of adding some additional caching of a minute or two to circumvent those situations, but we haven't tested that strategy.
