We have 2 DNS servers and randomly when we move a machine to a different VLAN, the DNS entry never registers the new IP. 0 Hello, In the last 5 months we just started adding Windows 7 Pro x86 computers to our Domain.These clients provide a persistent addressing method for devices that change their location, configuration or IP address frequently.
The term is used to describe two different concepts.
The first is "dynamic DNS updating" which refers to systems that are used to update traditional DNS records without manual editing.
I check DNS on the server about an hour later and there is still no record showing up.
I can use nslookup and it shows the server and the address fine.
The tables were maintained manually in form of the host file.
The Domain Name System brought a method of distributing the same address information automatically online through recursive queries to remote databases configured for each network, or domain.
These can be added to DNS and will always be available. But, I need a pool for a set of virtual hosts that are being configured. config files, but my DHCP/DNS provides the IP addresses as the vhosts are launched or retired.
Even simpler is to use fixed IP addresses for the virtual machines.
These mechanisms are explained in RFC 2136, and use the TSIG mechanism to provide security.
The second kind of dynamic DNS permits lightweight and immediate updates often using an update client, which do not use the RFC2136 standard for updating DNS records.
You must carefully weigh the convenience of this facility for users against the security risk created when you enable dynamic DNS updates.
