Hello Vladimir-san,

I set config as follows.

-- Load Useful modules

modules = {

'policy', -- Block queries to local zones/bad sites

'view', -- Views for certain clients

'hints > iterate', -- Hints AFTER iterate

'stats', -- Track internal statistics

'priming', -- Initializing a DNS Resolver with Priming Queries implemented according.

'detect_time_skew', -- System time skew detector

'detect_time_jump', -- Detect discontinuous jumps in the system time

'daf',

'version',

predict = {

window = 180, -- 180 minutes sampling window

period = 24*(60/15) -- track last 24 hours

},

'bogus_log',

}

-- Cache prefilling

modules.load('prefill')

prefill.config({

['.'] = {

url = 'https://www.internic.net/domain/root.zone',

ca_file = '/etc/pki/tls/certs/ca-bundle.crt',

interval = 86400 -- seconds

}

})

modules.list() -- Check module call order

For all contents, please check the following.

Is it necessary to check dump?

What's your configuration? I didn't try now, but you are getting a http redirect to https://www.internic.net/domain/root.zone and our documentation suggests to use that exact URL.

Still, I expect it would be nice to make the implementation follow redirects anyway...
