Root Zone Change Tracker

Introduction

The zone is transferred daily at 8:10am Pacific Time (GMT -0800) using dig @C.ROOT_SERVERS.NET . AXFR and checked into RCS (revision control).

As such, this RCS file (root.zone,v) can be used to show the exact changes in the DNS root zone and status between any two given dates.

Analysis

We provide the raw data free of charge, but analysis must be done yourself, or Credentia can do it for a fee.

Please use a *NIX system to analyze the revisionized root zone. Most unix systems contain RCS already installed. If you must run windows, consider PC-RCS.

Download the root DNS zone delta file .

Issue the following command to ensure your system can see the revisions

rlog root.zone

If everything looks good, you can proceed with showing changes between any two dates. For instance, let's say you need to know what changed between the April 12 and April 14th of 2004. First, you examine the output from the rlog command issued above, to get the revision numbers (eg. 1.2) that correspond to those dates. Then you can plug those revision numbers into the rcsdiff command to show the actual changes in (unified) diff format.

rcsdiff -u -r1.1 -r1.3 root.zone
