Even this DNS facility still used static lookup tables at each participating node.after you have created an account with them, and after you have told them the name of your domain.If you’re like many Dyn DNS customers, you have a dynamic IP address which changes periodically (monthly, weekly or even daily).
If you manage your domain's Office 365 records at your DNS hosting provider, you don’t have to worry about the steps in this topic.
Your website stays where it is and people can still get to it.
If you're running Samba as Active Directory Domain Controller, you also have to administer a DNS server.
You will already find general information on the internal DNS and the BIND DLZ module and documentation about Bind as DNS Backend in the Wiki.
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.
An update client is a computer application or a feature in your router that keeps your hostname’s IP address up-to-date.
The update client periodically checks your network’s IP address; if it sees that your IP address has changed, it sends (updates) the new IP address to your hostname in your Dyn account.
That's why both backends don't yet cover all the features that you can setup with the Microsoft DNS tools.
