The resolver usually takes the first IP address, but I'm not sure if this is required. Caching is more of a problem if you want to do your own load-balancing. The recommended solution is usually to use short TTLs. Interestingly, BIND also supports round-robin DNS based on aliases. If you put multiple CNAME entries in the database, the one you get back alternates between the aliases, e.g., server cname foo cname bar cname quux foo a 10.0.0.10 # first return this name bar a 10.0.0.11 # 2nd request gets this quux a 10.0.0.12 This isn't actually defined as meaningful in the relevant RFCs. But I think it's nicer when you want to enforce a 1 canonical name <-> 1 address policy.
