Updating bind serial numbers authority

01 Apr

Now imagine that our network administrator decides for some reason or another to move the mail server to the machine 192.168.0.11.The only thing that has to be changed is the DNS server configuration file.(Although it's possible to access some sites using only the IP address of their web server, this is not the case for virtual websites, which require that their hostname be included in the HTTP request header.Without a working DNS record, virtual websites are completely inaccessible.) But I've found that DNS is something that is not well understood by many website operators.There are two configuration parameters that can be used within the powerdns configuration file.

By if you are using third-party name servers which you do not control as your secondary name servers (such as Peer 1's Super DNS servers), then these settings are vitally important to how fast any changes are propagated.

You could always go and modify the host configuration for all the users, but that would be time consuming and inconvenient.

We get internet access through an xxxbox (192.168.1.1), two DNS servers provided by our ISP (.2, .129).
