We have a very large network (18K clients, 1200 servers), and I inherited DNS -- running Win2k3 AD with MS-Integrated DNS. One problem is that we have hundreds of DNS Reverse Lookup zones (in-addr.arpa), many of which have overalpping ranges. i.e.
These zones contain both static and dynamic PTR records. This is working, for the most (records are normally added to the most specific zone), but in an effort to cleanup and ease administration (since many zones are miscofigured with different aging, scavenging, allow dynamic updated, etc), I would like to consolidate the more specific ranges to the higher level CIDR range.
Is there a problem doing this type of consolidation? What do I need to be careful of with the static records? Most importantly, does anyone have a script, perhaps using DNSCMD, that would make this job easier? This needs to be seamless to the users, of course.
I read one of Chris-Dent's threads that sounded like he may have a script for this. Chris?
