##
# Construct an exclusion search query for Datadog log search for Tenable IP address ranges.
#
# Datadog does not seem to be able to reliably use CIDR notation but
# if we know the start and end of each IP address range we can construct a single compound query.
# Here we retreive the latested published list of IP address ranges and filter that down to
# the short list of regions we care about.
