pdns everydns.net as secondary dns
in /etc/powerdns/pdns.conf
allow-axfr-ips=71.6.202.218,66.240.223.182
disable-axfr=no
disable-tcp=no
master=yes
make sure you insert the value 'MASTER' on the column 'type' in the domains table
add the domain with advance option "make secondary using", and specify the primary dns (server ip where you install powerdns).
the last thing to do is to modify the domain dns records to
ns1.everydns.net
ns2.everydns.net
ns3.everydns.net
ns4.everydns.net
