dns slave auto configuration

Posted on June 30, 2013

There’s a DO tutorial about setting up ‘dns slave auto configuration’ however it doesn’t explain why i would want to do it, and what it actually accomplishes. Can you explain. For example,

  1. is the master/slave set up described in the article going to make a duplicate copy of all the data, or does it have nothing to do with copying the database?

  2. will it result in higher performance somehow?

But how does the slave keep a copy of the master if the database on each server isn’t linked?

@m73mitchell, <br> <br>Take a 2nd look at the title of the article you cited: “How to Setup <strong>DNS Slave</strong>…” The configuration outlined in that article only copies DNS records from the master server onto the slave server(s). <br> <br>Thus, it will not “keep a copy of the master if (sic) the database on each server.”

Thanks Pablo but then why would I want to do it? Why do I want to copy DNS records from the master server onto the slave server? What benefit does that provide?
