Transform Meta Info
|Display Name||To Netblock [Blocks delegated to this NS]|
|Transform Name||NS RecordToNetblock_NS4block|
|Short Description||This Transform will contact Robtex and determine if the NS record has any (reverse) DNS netblocks delegated to it.|
This Transform works on NS Record‘s. It determines if the particular name server has any Netblock reverse DNS delegated to it. This is useful for finding Netblock of an organization. What's interesting about the results of this Transform is that an organization might have a class B network (a fairly large netblock), but, in reality are only using a couple of class Cs (smaller netblocks) within that block. In many cases they will only populate the reverse DNS of these smaller blocks and delegate it to their name servers. The Transform will show these smaller blocks.
