• 192.168.1.0/24 - home lan network
• 192.168.1.100 - router
• 192.168.1.251 - raspberry
• rpi-dns - hostname of the raspberry
• 208.67.220.220, 208.67.222.222 - opendns

let´s start

sudo su
apt-get install bind9

cd /etc/bind
nano /etc/bind/db.home.lan

content:

; Use semicolons to add comments.
; Host-to-IP Address DNS Pointers for home.lan
; Note: The extra "." at the end of the domain names are important.
; The following parameters set when DNS records will expire, etc.
; Importantly, the serial number must always be iterated upward to prevent
; undesirable consequences. A good format to use is YYYYMMDDII where
; the II index is in case you make more that one change in the same day.
home.lan. IN SOA raspberry.home.lan. hostmaster.home.lan. (
2015120101 ; serial
8H ; refresh
4H ; retry
4W ; expire
1D ; minimum
)
; NS indicates that raspberry is the name server on home.lan
; MX indicates that raspberry is (also) the mail server on home.lan
home.lan. IN NS rpi-dns.home.lan.
home.lan. IN MX 10 rpi-dns.home.lan.
; Set the address for localhost.home.lan
localhost IN A 127.0.0.1
; Set the hostnames in alphabetical order
rpi-dns IN A 192.168.1.251
router IN A 192.168.1.100

u can also enter the address of your router (192.168.1.100) because he always refers to the current ip dns server of your provider's

nano /etc/bind/named.conf.options

forwarders {
192.168.1.100;
};
