  Host Discovery and Connection Data Blocks
User Criticality Change Data Block 4.7+
The User Criticality data block is used to contain a list of IP address range specifications for hosts where 
the host criticality changed, the identification number for the user who updated the criticality value, 
information about the source that supplied the criticality value, and the criticality value. The User 
Criticality data block has a block type of 81 in the series 1 group of blocks. Changes from the previous 
User Criticality data block include a new source type field and the use of the Generic list data block 
instead of the List data block to store IP addresses. 
The User Criticality data block is used in user set host criticality messages as documented in 
.
The following diagram shows the basic structure of a User Criticality data block:
Generic List Block 
Length
uint32
Number of bytes in the Generic List block and encapsulated data 
blocks. This number includes the eight bytes of the generic list block 
header fields, plus the number of bytes in all of the encapsulated 
data blocks.
User Vulnerability 
Data Blocks
variable
Encapsulated User Vulnerability data blocks up to the maximum 
number of bytes in the list block length. For more information, see
