First of all you can't just say... &quot;Oh this IP address doesn't ping, or doesn't get any results from nmap therefore I should be able to use it.&quot;<br />
<br />
IP's are controlled and assigned to specific service providers. &nbsp;Those service providers assign you IP's based on your needs and contract. &nbsp;So I have a /29 network assigned to me on my VPS(Virtual Private Server). &nbsp;If I am only using 3 addresses currently, it doesn't mean the other 2 are &quot;up for grabs,&quot; they are still MY addresses. <br />
<br />
The gov/military owns Millions of IP's that are not currently being used. &nbsp;It's just how the world of public addressing works. &nbsp;<br />
<br />
Find a service provider. &nbsp;Sign up for services through that provider. &nbsp;Get assigned IP's to use.

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.

The Windows operating systems have distinct methodologies for designing and implementing networks, and have specific systems to accomplish various networking processes, such as Exchange for email, Sharepoint for shared files and programs, and IIS for delivery of web pages. Microsoft also produces server technologies for networked database use, security and virtualization.
