To Netblocks in this AS [RobTex]

This transform expands an AS Number to one or more netblock Entity. This transform is very useful in the infrastructure foot printing of an organization. Let us assume that Org. X owns a couple of netblocks, but only has a single DNS Name that points to a single netblock - the other netblocks have no DNS information (e.g. no forward DNS pointing to it, or reverse DNS entries in the block). Using this transform we can find the AS NumberEntity of the netblock. Once we have the AS number we can expand it to all the other netblocks that Org. X have.
