There are some domains I query a lot, as there are monitoring tools running checking stuff there. I have no control over were this stuff is hosted, and the provider does not allow controlling the TTLs of even custom DNS records, but inappropriately uses a very low value instead, increasing my overall outgoing DNS queries quite a bit for no good reason. It's not tragic, but if I could fine-tune this, it would be nice. Then regarding neg-ttl, one of the domains I monitor behaves badly in another way, for some records it correctly gives NXDOMAIN, but without SOA (due to a nameserver "bug"), which prevents proper caching. neg-ttl "solves" this somewhat, but not really well, again choosing a proper value for this specific domain would be preferred. On the other hand, if you think this is a bad idea, surely doing it for all domains must be worse, right? But the options exist, and I assume for a reason, and whatever these reasons were, they most likely can be applied to single domains as well. _______________________________________________ Dnsmasq-discuss mailing list Dnsmasq-discuss@lists.thekelleys.org.uk https://lists.thekelleys.org.uk/cgi-bin/mailman/listinfo/dnsmasq-discuss
