The pound config may contain the name (not the IP) of the backend(s), but pound seems to resolve this name only once at startup. We came across this when we had a backend using a dynamically assigned IP. We (my college) wrote "dynamic IP" patch for pound, with this patch (and a new config option) pound resolves the host name(s) each time. Of course, this causes some additionally load, but if you're using a local caching resolver (obeying TTLs), it should be acceptable. BUT -- this patch was not written with performance but with flexibility in mind! > 2.
