Raw log file format

Simple DNS Plus raw log files (.sdraw) contain an entry for each received DNS request as follows:

Bytes	Description
3	Number of seconds since midnight *
2	DNS request packet bytes 3 and 4 (header flags)
2	Query type *
2	Query class *
1	Length of query name less 1
variable	Query domain name (DNS packet format)
1	Length of request source IP address (IPv4=4, IPv6=16)
variable	Request source IP address

* bytes represent integer value in network byte order (most significant byte first / big-endian).

The Tools directory contains a command line tool to extract and filter raw log data and also a .NET programming library for accessing the raw log data.

Raw request logging is enabled in the Options dialog / Logging / Log Files section.
