Hello.
Looking at the verbose logs, kresd sometimes gets incorrect replies from
root servers, e.g. from 198.41.0.4. I'm >99% certain there's someone
intercepting the packets between you and the servers, even over TCP,
probably trying to "optimize". It's hard for me to predict how such a
situation will play out.
Apparently you don't have working IPv6, so adding `net.ipv6 = false` to
your config can help a bit.
