Dns server reverse lookup zone not updating
The second line in each script requires a tad of explanation.In order to set IPv6 to use DHCP instead of pointing to local loopback (::1), we have to use the . Well, your dns resolving doesn’t return true unless we do this as it ‘catches’ the IPv6 before it gets to IPv4, so unless you specify your IPv6 you need to set this to DHCP.
With the default settings, a duplicate A record gets registered by DHCP with the client’s new IP.
This is because the client will not update itself due to the current record in DNS is beyond the lease period.
The first domain controller in the tree hosts the DNS server by default.
For other DSf W installations, such as child and additional domain controllers, the DNS server is optional and is not enabled by default.
If there's a space, then there's a space (and resolution will fail).
There is no where to configure a default domain name (search domain) and if you use a Fully Qualified Domain Name (FQDN), resolution will fail.
This happens even though DHCP registered the record.
This is because DHCP doesn’t own the record, the client does, even though DHCP registered it. If you have Windows 2008 R2, in addition to configuring the DNS tab to force registration, you still must configure credentials and add the server to the Dns Update Proxy group.
So, we already enabled Scavenging and Aging on our server, and now we want to setup a Reverse Lookup Zone.
Before proceeding, make sure your DNS settings are poitning the right way and you have set IPv6 to DHCP instead of loopback (::1) unless you actually have configured IPv6.
I'm a big fan of the Ubiquiti Uni Fi networking gear, I wrote about how I was able to use their gear to provide micro-segmentation of my Io T devices from the rest of my network.
