IPv6 Addressing
Understanding IPv6 Addressing
Larger address space
The main advantage of IPv6 over IPv4 is its larger address space. The length of an IPv6 address is 128 bits, compared to 32 bits in IPv4. The address space therefore has 2128 or approximately 3.4×1038 addresses

Top Network Management Tools in 2014
1- Solarwinds Network Performance Manager 10.5
Solarwinds is a heavyweight in the network-monitoring world, and for good reason. For years, Solarwinds NPM has provided all-round monitoring capability. With the release of NPM 10.5, Solarwinds has dropped the “Orion” product branding (it’s now officially ‘Solarwinds Network Performance Manager’ or ‘NPM’) in addition to stepping up the scalability of their game. NPM 10.5 has several new features and many improvements.
NPM 10.5 can handle basic SNMP monitoring and alerting just like always. New features include VMware & Hyper-V monitoring; and ConnectNow, an automated network mapping tool. ConnectNow appears to be based on the old LanSurveyor tool, but now nicely integrates into NPM. Improved historical trend reporting is also a welcome change. And, a redesigned UI rounds out the list of improvements.

What is Unix
What is Unix ?
The UNIX operating system is a set of programs that act as a link between the computer and the user.
The computer programs that allocate the system resources and coordinate all the details of the computer's internals is called the operating system or kernel.
The UNIX operating system is a set of programs that act as a link between the computer and the user.
The computer programs that allocate the system resources and coordinate all the details of the computer's internals is called the operating system or kernel.
Users
communicate with the kernel through a program known as the shell. The
shell is a command line interpreter; it translates commands entered by
the user and converts them into a language that is understood by the
kernel.
Unix was originally developed in 1969 by a group of AT&T employees at Bell Labs, including Ken Thompson, Dennis Ritchie, Douglas McIlroy, and Joe Ossanna.
There are various Unix variants available in the market. Solaris Unix, AIX, HP Unix and BSD are few examples. Linux is also a flavor of Unix which is freely available.
Several people can use a UNIX computer at the same time; hence UNIX is called a multiuser system.
A user can also run multiple programs at the same time; hence UNIX is called multitasking.
