Hi!
I tried to summarize the options at http://sip-router.org/wiki/cookbooks/core-cookbook/devel#dns_parameters
Please review and fix if something is wrong.
Replaced dns_cache_init=off with use_dns_cache=off. The difference is that if use_dns_cache=off, but dns_cache_init=on (default), the cache can be enabled anytime at runtime (e.g. sercmd cfg.set_now_int core use_dns_cache 1). If dns_cache_init=off, the cache cannot be enabled at runtime (requires a restart), but you save a little bit of memory (it might matter on embedded systems).
btw: are the tuning options like dns_try_ipv6, dns_retr_time, dns_retr_no, dns_use_search_list .... also used when the internal resolver is used?
Yes, the ones above are used both when the cache is enabled or disabled. The ones that are not are some of the dns_cache_flags: ipv6_only and prefer_ipv6 are obeyed only if the cache is used.
