The following table describes the fields of the BLOB data block.

The List data block is used to encapsulate a list of series 1 data blocks. For example, if a list of TCP 
servers is being transmitted, the Server data blocks containing the data are encapsulated in a List data 
block. The List data block has a block type of 11 in the series 1 group of blocks.

The following diagram shows the basic format of a List data block:

The following table describes the fields of the List data block.

BLOB Block Type uint32

Initiates a BLOB data block. This value is always 

10

.

BLOB Block 
Length

uint32

Number of bytes in the BLOB data block, including eight bytes for 
the BLOB block type and length fields, plus the length of the binary 
data that follows.

Binary Data

variable

Contains binary data, typically a server banner.

List Block Type

uint32

Initiates a List data block. This value is always 

11

.

List Block Length

uint32

Number of bytes in the list block and encapsulated data. For 
example, if there were three sub-server data blocks included in the 
list, the value here would include the number of bytes in the 
sub-server blocks, plus eight bytes for the list block header.

Encapsulated Data 
Blocks

variable

Encapsulated data blocks up to the maximum number of bytes in the 
list block length.
