We will start by copying the files so we have a backup remaining if anything goes wrong: 1.1 Copy the zone database files: We now need to add the key to the bind configuration and tell it what zones that we want it to allow updates on.
I’ve included the whole contents of my file here and marked the changes that I’ve made in bold.
Information The steps in this post shows how to configure the DHCP server to automatically update the DNS records when giving out a new lease to a client computer. Before continuing These steps assumes that you already have a working copy of isc-dhcp-server and bind9 installed.
These mechanisms are explained in RFC 2136, and use the TSIG mechanism to provide security.
Microsoft Windows operating systems support a feature that dynamically updates the mappings of domain names to associated IP addresses assigned to hosts by DHCP servers.
This automatic updating, called Dynamic DNS Updates service, reduces the administrative overhead associated with manually administering DNS records of network hosts.
While this service can reduce administrative overhead, it also can, and does, have deleterious effects on the larger Internet by leaking traffic regarding private IP addresses that should never leave the local area network.
You do not need to disable dynamic DNS updates if: However, if you have configured your host to act as a DHCP client/server and you make use of the private IP address space (including 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16) specified in RFC1918, you should turn off the dynamic DNS update feature.
