* John Levine:
Are there DNS caches that allow you to partition the cache for subtrees of DNS names? That is, you can say that all entries from say, in-addr.arpa, are limited to 20% of the cache.
You can build something like that using forwarders and most DNS caches. But it won't result in an exact split because cross-subtree CNAMEs and DNS delegations will cause caching outside the subtree. However, for in-addr.arpa, that's probably what you want anyway.
