I tried giving NextDNS a shot. So far it looks great. My only problem it has 300k query limit for free in a month. I tried investigating the source of problem by looking a bit into about:networking and found out many queries has time to live of 300 seconds. I tried turning nextdns cache boost off and on but it made no difference. In order to reduce number of queries i send i set network.dns.get-ttl false (i don't know if it relevant since i am using DNS-over-https), network.dnsCacheEntries 1000, network.dnsCacheExpiration/network.dnsCacheExpirationGracePeriod= 43200. While this setting sometimes apply to one or two queries occasionally it was pretty much ignored most of the time. I am on windows 10 and using arkenfox user.js. Does anyone have any idea how i can force a higher ttl on dns cache?
