Computers, like people, first on their own, then on the system. Of course, this person creates a computer system (network), but through generations of specialists this system (network) “controls” its development process. This stems from the actual development of the Internet space and the role that the DNS name hierarchy plays in it.
NSLookUp team: a description of the possibilities, the result of a single computer’s path to the Internet, specialists into the world of creating tools for distributed information processing, and users into an understanding of how everything is really arranged.
Start story: simple networks
The world of the Internet was formed "on its own", although it is impossible to deny the essential role of both individual specialists and qualified development teams. But when quantity goes into quality, roles often change. The computer has not yet gained intelligence, and the topic of artificial intelligence has long become habitually uninteresting: for a long time, man has not been the only and main symbol and engine of progress.
The creations of human hands not only “live” their own lives through space and time, but also “exert” the opposite effect on the activities of new generations of specialists.
Combining computers on a network came naturally. Specialists quickly came to an understanding. Users are accustomed to working in a team when actions on one computer lead to a change in something on another. The network organization of elements and processes has found its application in almost all areas and has become familiar.
Got embodied in reality, various network protocols became natural and convenient , and computers "learned" to negotiate with themselves.
Distributed networks
Ever since the birth of the network, they quickly changed the face of the information sphere, but it was still far from programming. Spectacular and practical network examples have become the norm, but it was not the Internet, it was not Internet programming yet.
The creation of training programs that automate the operation of several computers to educate students, even those in different classrooms / buildings, was only unique and significant at the time of creation.
Automation of the production process of something, combining into a single whole a multitude of sites, processes, suppliers, consumers, was also an important and necessary, but “minute” achievement.
Any other network applications were unique and interesting at the time of development, implementation and commissioning, then they immediately became familiar and mundane. The consumer immediately forgot how he used to live before applying this or that network application.
NSLookUp - The Outcome of the Beginning or Path of the Network
We must pay tribute to Windows , it has a noble role in the information field. But there is no guarantee that it was here that the inconspicuous NSLookUp appeared. The idea is good and the Unixoid family can declare its contribution to its birth. Commands for working on the network are needed, but the vast majority of them are invisible, although very significant. NSLookUp appeared on Windows NT and similar systems, as well as on other platforms. Now it is in demand always and everywhere.
You may not go into the vicissitudes of the development of network ideas, but know that NSLookUp commands allow you to quickly and accurately identify a problem on the network, this will be useful even for a simple user.
To the network administrator and system designer, this command opens up convenient possibilities. In fact, it is an analogue of the DNS client service (NSLookUp online is especially convenient) and allows you to make an objective diagnosis of name resolution problems. This was the result of the development of networks. Probably, the idea of distributed DNS servers will have different content and organization in the future, but at the given time, using NSLookUp commands, you can get accurate and necessary information, both for practical use and for identifying problems.
It is important to understand that the development of network technologies, in the end, was concentrated in a certain protocol stack, a combination of various computing platforms, existing systems and processes. And it is not at all necessary to have a complete understanding of what it is to be a confident user, developer or administrator. In most cases, it’s enough to have an idea of what NSLookUp commands are.
Symbols and their identification
What is part of the work of administrators and developers, NSLookUp-teams provide ordinary users in a simple and affordable way. Having taken quite a bit of time studying the parameters, options and rules for using this tool, the user will get an accurate idea of what a domain is, DNS, IP, A, AAAA, Refresh, TTL, etc. All these symbols and terms appeared in their time, bear the specific meaning, and when something goes wrong, you can not even resort to qualified help when there is the practice of using the NSLookUp command in the arsenal.
Interactive access to the domain on the network allows you to obtain the necessary information manually. NSLookUp online operation is provided through the command line. You just need to set the desired output parameters and get the required data.
Using NSLookUp
Usually, the NSLookUp command (examples from practice) is applied according to one single rule: nslookup-type = any-timeout = 8 vk.com 208.67.220.220, and there will be comprehensive information on the VKontakte site, but nothing will be found for the sophisticated user prevents you from exploring all the parameters of the team or choosing your own version and your standard form for practical use.
