i was looking at comments at idea center ….  schumaku commented …. on Page 4 … that

To my knowledge the dnsmasq config isn’t configued to speed-up or cache anything … see “cache-size=0” …

 

But to make it worse – and on the R9000/R8900 this was removed a while ago as we spent a lot of time dealing with Netgear – was the “try-all-ns” config … an option no longer in dnsmasq config and docs for years (if not a decade). What it does enforce is fatal: Every request will be sent to all the typically up to three ISP or Internet connection configued DNS IPs and not come back with a valid answer before all DNS servers have replied. Complete silly. And I’m convinced this nonsense is still in place on many Netgear router models (Cxxxx, Dxxxx, Rxxxx, Nighthawk, Orbi, whatever).

As a side effect,  it does make dnsmasq return a wrong status code if a domain can’t be resolved.

root@R9000:/etc# cat dnsmasq.conf
# filter what we send upstream
domain-needed
bogus-priv
localise-queries
no-negcache
cache-size=0
no-hosts
try-all-ns
root@R9000:/etc#

i was also looking at Netgear community for that and found – https://community.netgear.com/t5/Nighthawk-WiFi-Routers/R9000-DNS-Performance/td-p/1461774
