Some people have mentioned that they think that bind messes up these files so that they are impossible to maintain.authoritative; # Use this to send dhcp log messages to a different log file (you also # have to hack to complete the redirection). I don’t think that they are that bad and personally I don’t have any problem editing them after that bind has rewritten them.As soon as Name Protection is enabled, the DHCP server is automatically configured to behave as specified in [‘scenario 1’].The DHCP server will always register a DNS record on behalf of the DHCP client whether or not that DHCP client actually requests it.With this configuration the DHCP server will always register a DNS record on behalf of the DHCP client whether or not that DHCP client actually requests it.In this case you will see that after the DDNS registration/update both the ‘A’ DNS record and the ‘PTR’ DNS record are owned by the user account specified as DDNS credentials in DHCP.Run the following command to retrieve a list of all 130-odd Power Shell DNS functions: Get-Command -Module DNSServer | Select-Object -Property Name Use Get-DNSServer to retrieve the local server's configuration data.In the following example, I use Set-DNSServer to migrate configuration data from server01 to server02: Get-Dns Server -Cim Session 'server01' | Set-Dns Server -Computer Name 'server02' Of course, we use the native Power Shell *-Service cmdlets to operate on the server directly.

This launches the New Zone Wizard, which will ask us to specify the following information: Zone type. By default, your new zone will have two DNS records: Start of Authority (SOA): This record identifies which server is authoritative for the zone Name Server (NS): This record identifies the servers that host records for this zone Right-click the new zone and you'll see various resource record creation options directly in the shortcut menu; these include: Host (A): This is your "bread and butter" record that identifies a single host Alias (CNAME): This record allows you to map more than one hostname to a single IP address Mail Exchanger (MX): This record identifies your company's e-mail server(s) that are attached to the current DNS domain We'll finish today's tutorial by using Power Shell to define a new A record for a host named 'client1' and verify its existence.

I’ve included the whole contents of my file here and marked the changes that I’ve made in bold.

3.1 Edit /etc/bind/local: # # Make sure to change the ddns update style to interim: ddns-update-style interim; ignore client-updates; # Overwrite client configured FQHNs ddns-domainname ""; ddns-rev-domainname ""; # option definitions common to all supported networks... subnet .0 netmask 255.255.255.0 The dns database files are now being rewritten by the bind service.

In the "DHCP Request" message you can see the DHCP client is requesting to self-register the ‘A’ DNS record.

Because of the DHCP server configuration, the DHCP server is overriding that request and is telling that to the DHCP client in the "DHCP Ack" message.
