Ntpv1 Case 8. 1

A hierarchical system of servers and services specifically designed to translate IP addresses into domain names (forward lookups) as well as the reverse (reverse lookups) is called:

Domain structure – the Domain Structures allows the users or the program to interpret different information. For example take the address: http://www.netflix.com/

2. What does the /etc/resolv.conf file do? What do the nameserver lines in this file do?

When you type in a web address, e.g.www.google.com. DNS associates with the domain name, translates into IP address (for example 192.168.154.70 is the IP for google.com) and directs your Internet connection to the correct website.

DNS is a commonly used service in the Internet. Explain the roles of the local name servers, the authoritative name servers, and the root name servers.

The IP address is given a unique identification it is one of kind IP address, so it can be trace for any internet activity and find the exact location of website. Domain names are used because it is easier to remember the name rather than the entire website address. All computers on the net have what area unit termed net Protocol addresses ordinarily called associate degree scientific discipline address to be ready to communicate across the network. These addresses, that area unit assigned to all or any computers on a network, area unit created of numerals separated by a dot that don't seem to be essentially simple for North American country to recollect. Therefore, whereas computers simply use these scientific discipline addresses to attach and communicate with one another, it's somewhat more difficult for North American country. It's with keeping such in mind that, net designers and controllers have return up with a translation system that identifies additional simply remembered characters with every and each scientific discipline address. With DNS we need to have the integrated namespace so following DNS use is proposed: an internal DNS namespace, used only on your own network; internal DNS to communicate with external DNS forwarding; and an external DNS namespace to communicate with external

DNS stands for ‘Domain Name System’. It is an internet service that works like a

Q. What is tree? A. A group of domain is called tree and sharing a contiguous Name Space. Q. What is forest? A. A group of tree is called forest and does not sharing a contiguous name space but sharing a common configuration (Schema). Q. Difference between D.C. and A.D.C.? A. D.C. stands for Domain Controller and A.D.C. stands for Additional Domain Controller. A.D.C. is a backup of D.C. Only one different is available between D.C. and A.D.C. i.e. – Operation master Role. On D.C. all of five Operation Master Roles are available1. Schema Master 2. Domain Naming Master 3. RID Master 4. PDC Emulator 5. Infrastructure Master But on A.D.C. only Three Operation Master Role are Available: 1. RID Master 2. PDC Emulator 3. Infrastructure Master Q. What is the benefit of Child Domain? A. There are many benefits of Child Domain Such As: 1. Security Boundary 2. Administrative Overhead Low 3. Network Traffic Low Q. What is Group? A. Group is a collection of user account. It provides the simplified administration in the network.

DNS- DNS stands for domain name server and is a network of servers that keep track of Internet Domain Names. Its main job is to authenticate and find domains. It translates IP Addresses into numbers, for example, 172.194.40.143 translates into

The zone is the administrative division that DNS servers use to separate domains. The first step in implementing the DNS namespace you designed is to create a zone representing your root domain.

We're having an issue with the office network. Each of our computers has been running really slow for at least a week. Over the last few days our computer searches/email retrievals frequently time out with the message: "The DNS is not responding, please try again," it can take up to three tries to reach the requested URL.

The Internet is, quite literally, a network of networks. It is comprised of ten thousands of interconnected networks spanning the globe. The computers that form the Internet range from huge mainframes in research establishments to modest PCs in people's homes and offices. Despite the recent hype, the Internet is not a new phenomenon. Its roots lie in a collection of computers that were linked together in the 1970s to form the US Department of Defense's communications systems. Fearing the consequences of nuclear attack, there was no central computer holding vast amounts of data, rather the information was dispersed across thousands of machines. A set of rules, of protocols, known as TCP/IP was

P1: The first method in network addressing is, Fully Qualified Domain Name which is known as FQDN for short. FQDN is used as the domain name for a specific host or computer name on the internet. FQDN consists of two main parts, the domain name and the hostname. For example, Belfast Met is the hostname, but the domain name is belfastmet.ac.uk.

The Domain Name System is most often described as the Internet’s phone book or address book. All of us Internet users use it on daily basis without even realizing it. Its basic task is to convert human-readable website name like coursera.org into its computer-readable numerical IP address like 107.21.240.231.Since such strings of numbers are difficult for humans to memorize, DNS allows you to assign a domain name, such as facebook.com to you IP address. So, the domain name is simply an address on the Internet. It has to be unique just like physical address or phone number.
