DNS Domain Research Paper

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

The /etc/resolv.conf file is the resolver configuration file. It provides access to DNS for Internet address resolution. The nameserver line indicates which systems the local system should query to resolve hostnames into IP

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 the service that translates from domain name to the matching IP address. The roles of the name servers in this process are:

For DNS we need also to test how long it takes authoritative DNS servers to respond to a request for your domain or host, including the Domain, the TLD, and the Root DNS server response times. This test provides us with information to help identify possible DNS hosting performance delays resolving our domain. It can be useful when evaluating the DNS performance of hosting providers, and general troubleshooting performance of a

Network Security - Networks are classified into many types like shared and non-shared, public or private, small area or large area networks and each of them have a number of security threats to deal with. Problems associated with the network level security comprise of DNS attacks, Sniffer attacks, issue of reused IP address, etc. A Domain Name Server (DNS) server performs the translation of a domain name to an IP address. Since the domain names are much easier to remember. Hence, the DNS servers are needed. But there are cases when having called the server by name, the user has been routed to some other evil cloud instead of the one he asked for and hence using IP address is not always feasible. Although using DNS security measures like:

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

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.

A malicious node can impersonate or spoof the address of another node in order to alter the vision of the network topology as perceived by another node. Such attacks can result in the formation of loops as described below [18]

This is domain name that is considered to be your account’s main domain. It is the domain you use to log into your Bluehost account and the domain you use when dealing with Bluehost representatives. There can only be one primary domain per account.

The goal of this case study is to follow a packet capture file to investigate the fictitious character Ann Dercover. Examining the file will show how she uses network tunneling to cover her tracks, but more importantly, it will help develop skills that can be applied to network forensics. The challenge is to determine if the DNS traffic is truly suspicious, determine the purpose of the DNS traffic, recover all possible information on the local and remote systems involved, and the risk associated with the data leaking from the organization.

The internet is a medium that is becoming progressively important as it makes information available in a quick and easy manner. It has transformed communications and acts as a global network that allows people to communicate and interact without being limited by time, boarders and distance. However, the infrastructure is vulnerable to hackers who use the system to commit cyber crime. To accomplish this, they make use of innovative stealth techniques for their malicious purposes in the internet.
