hi i want to share a little configuration if u want build dns server powerfull. yess that'is a dnsmasq..

first we install dnsmasq in your server

log-queries
domain-needed
bogus-priv
no-hosts
dns-forward-max=500
cache-size=1000
#no-negcache
neg-ttl=3600
resolv-file=/etc/resolv.dnsmasq
no-poll


finish we save, then we add more configuration for dns cache query with filename /etc/resolv.dnsmasq

nameserver 8.8.8.8
