I thought unbound's prefetch kept the cache full all the time, not just when a nearly-expired name is gotten from the cache. HAMMER specifically grabs only when a name is used again close to its expiration. Or am I misunderstanding the unbound documentation? --Paul Hoffman _______________________________________________ DNSOP mailing list [email protected] https://www.ietf.org/mailman/listinfo/dnsop
