Good thing refuse-any is just a draft then isn't it. Now any v. Concurrent queries. To ensure the resolver gets all the RRs, wouldn't you have to query for all defined RR types? Perhaps you want ALL instead of ANY? /Wm On Thursday, 25 August 2016, Tony Finch wrote: > Edward

Very interesting, so BIND already pushes records for the obvious optimisation cases. Did you do any research on how many clients use these records (thus don't follow up with an extra query) ? Perhaps it would be helpful to look at the it from different perspectives. As an authoritative DNS

Or SRV. These are cases where authoritative/resolver adding interesting records as additionals works better. Authoritatives have been doing that with extra SOA/NS in authority for a while (for positive answers), but now resolvers can hardly use them if these records are not secure. Regardless of

Status Quo is good for ipv4 to ipv6 migration. Totally agree with william on PUSH/PULL. 1. Hotest internet service's RDATA always exists in recursive dns cache, PUSH is not speed up much except hit-miss. ( recursive -> authority ) 2. clients known what they want, PULL & prefething is Ockham's

from an attacker POV, I would strongly support PUSH, as it would increase DDoS effectiveness. The performance enhancement seems to be based on some presumptions about servers retaining residual knowledge of the resolver behaviours. PULL minimizes the attack surface. wrt cache coherence and delay,

my bad. I've been re-framed. Contextually, PUSH means (to me at least) 'do this promiscuously' and PULL means (to me at least) 'do this if asked' -which is not what I previously understood. In that case, I think PULL makes more sense: do this, if the client signals its what it wants. Otherwise,
