I use Splunk 6 (free) for some basic keyword searching. &nbsp;Generally I just add a specific IP address and a keyword, and I get a hit if it has been indexed. &nbsp;My IP ranges are usually Class C, and I just used something like 10.10.10.* when wanting to search for that particular keyword in the subnet.<br />
<br />
Recently I needed to do searches found in much larger IP ranges. &nbsp;For example 101.2.176.0 to 101.2.191.255.<br />
How would I define that range with Splunk? &nbsp;I have looked at some articles, and there they used 101.2.176.0/20 format, but for the life of me I am unable to get it to work in my Splunk searches.<br />
<br />
So, if my keyword was &quot;error&quot;, and my range was 101.2.176.0 to 101.2.191.255, how would I add that to a Splunk search?

Network analysis is the process of identifying and remediating the processes and systems within a network, including performance, connectivity and security. The process is performed through the use of tools developed for monitoring and analyzing network activity. Network problems that involve finding an optimal way of doing something are studied under the name combinatorial optimization. Examples include network flow, shortest path problem, transport problem, transshipment problem, location problem, matching problem, assignment problem, packing problem, routing problem, Critical Path Analysis and PERT (Program Evaluation & Review Technique).

Network Analysis

Network Management involves issues that are independent of specific hardware or software, including email policies, upgrade planning, backup scheduling and working with managed service providers for Desktop-As-A-Service (DaaS), Software-As-A-Service (SaaS) and the like through the use of tools, coupled with manufacturer standards, best practice guidelines, policies and procedures plus all other relevant documentation. Network management also includes monitoring, alerting and reporting, management reporting, planning for device or service updates, the backup of configurations, the setting of key performance indicators and measures (KPIs/KPMs), associated service level agreements and problem records as part of the IT Service Management (ITSM) framework.

Network Management

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.
