• You can search for IP ranges, including subnets. For example:
•
172.168.1.1/24
or
172.168.1.1/255.255.255.0
matches all IP
addresses in the subnet 172.168.1.1/255.255.255.0
•
172.168.1.1-140.255
matches all IP addresses from 172.168.1.1 to
172.168.140.255
• The search returns results that match all of the search terms.
For example, consider two similar keyword entries:
172.20.120.127 tcp
and
172.20.120.127 udp
. If you enter the keywords
172.20.120.127 tcp
, UDP traffic would not be included in the search
results, since although the first keyword (the IP address) matches, the second
keyword,
tcp
, does not match.
• The search returns results that match all, any, or none of the search terms,
according to the option you select in Match.
For example, if you enter into Keyword(s):
172.20.120.127 tcp
and if from Match you select All Words, log messages for UDP traffic to
172.20.120.127 do not appear in the search results, since although the first
keyword (the IP address) appears in log messages, the second keyword (the
protocol) does not match UDP log messages, and so the match fails for UDP
log messages. If the match fails, the log message is not included in the search
results.
