Error in bind server configuration

Question

I followed this tutorial to install a dns server on my local network: http://goo.gl/vkVC0A
My idea is to access intranet.empresa on the network pcs and fall on ip 10.0.0.220 which is a web server.
I did all the procedures in the tutorial, but when I test the server through my machine that has ip 10.0.0.108 with the bind command, I get the following error message:

$ dig intranet.equilibra

I freaked out about something?

Answer 1

If you are not going to use dnsmasq (as suggested by Rafael), see the dns configuration of the client machines in the file /etc/resolv.conf . It should look like the below:

search intranet.equilibra
nameserver 10.0.0.220

Do not put google DNS Ips here, as this will slow down the customer solving valid names on the internet. Instead, set up your DNS server to forward queries to other servers if the name cannot be solved by it, as dvm said. See the tutorial: tutorial Ubuntu

Answer 2

You are performing the query on the DNS server 8.8.8.8, if your server is for internal use only, you should perform the DNS queries for this domain directly on it and not on the internet.
