Note that dnsmasq _forwards_ any type of query and returns the result. Only caching is limited to certain types. TTL rewriting doesn't depend on caching, dnsmasq could easily rewrite the TTL for RR types it doesn't know how to cache. > > About changing the behavior, I think adding an option allowing to > choose which kind of queries must be cached can be a good > improvement. Let's see with the list. Have you seen how many options dnsmasq has already? If there's one sane way to do it, that should be how it's done.
