Secure your DNS Queries
As part of my home server setup (which warrants a post very soon), I’ve setup a DNSCrypt resolver. This was heavily inspired by Abhay (Nemo) who’s setup a DNSCrypt resolver on Digital Ocean in Bangalore.
My server takes the second number for DNSCrypt resolvers in Bangalore, INDIA.
Here’s the configuration for the tech guys and hence the
ProviderKey A6FA:B764:A3D7:A1C7:208D:11DA:0184:8602:81A5:0887:BC42:3DDE:FD33:CF77:0B7A:EFFF ResolverAddress 184.108.40.206:4434 ProviderName 2.dnscrypt-cert.qag.me
The server does not respond to insecure DNS requests on port 53. This means you’ll need to setup either Unbound / dnscrypt-proxy to get this going. I’ll put up a post on how to set this up shortly.
The server does not log any DNS queries. The only metrics I get out of the server are these:
total.num.queries=2357 total.num.queries_ip_ratelimited=0 total.num.cachehits=894 total.num.cachemiss=1463 total.num.prefetch=606 total.num.zero_ttl=2 total.num.recursivereplies=1463 total.requestlist.avg=4.02465 total.requestlist.max=31 total.requestlist.overwritten=0 total.requestlist.exceeded=0 total.requestlist.current.all=0 total.requestlist.current.user=0 total.recursion.time.avg=0.645631 total.recursion.time.median=0.889858 total.tcpusage=0 time.now=1519313244.596154 time.up=4252.237591 time.elapsed=4252.237591
What you get out of using a DNSCrypt based resolver is more important - No one knows what websites you’re asking for. Google does not need to know what you’re up to! They mine ONE LESS user’s data. The internet is a decentralised place! Lets try to keep it that way!
Since this is a DNS server, downtime at my end can break your internet. While all attempts will be made to keep this rolling strong, I have setup a (status page) to let you know if it does go down!
To an internet without the devils!
