At the end of the output of the command !heap -x -v 0x1784e350, after information about the heap block owning the pointer i'm investigating about, there is a "Search VM for address range" that is listing pairs of addresses, which I am wondering about.
What information can I grab from it ? What does it mean ?

Calling the command dd 0195d1dc L1 (the first address in the list) gave me the answer:
0:039> dd 0195d1dc L1
0195d1dc 1784e354
"Search VM for address range" lists all the addresses that contain a value which is in the range of the heap block investigated.
As a consequence, it lists all possible addresses which are maybe pointing inside the heap block which contains the address being investigated.
This can be incredibly useful.
