What Is A Dns Resolver
The DNS resolver is the first stop in the DNS lookup, and it is responsible for dealing with the client that made the initial request. The resolver starts the sequence of queries that ultimately leads to a URL being translated into the necessary IP address.
Note: A typical uncached DNS lookup will involve both recursive and iterative queries.
It’s important to differentiate between a query and a recursive DNS resolver. The query refers to the request made to a DNS resolver requiring the resolution of the query. A DNS recursive resolver is the computer that accepts a recursive query and processes the response by making the necessary requests.
How Does Domain Name Work
IP address allows communication over the internet between devices and networks connected to the internet. IP address is meant for computers so that it can easily identify a particular entity on the internet but these numbers are not easy to remember by humans, so it is converted into domain name with the help of DNS .
When individuals enter your domain name into a Web browser, the browser uses your domain name to find the right IP address and in turn provide back the website associated with that IP address.
What Was The First Domain
The first Internet domain name “symbolics.com” was registered by Symbolics, a Massachusetts computer company on March 15, 1985.

Selecting Your Logon Context In Windows Vista And Windows 7
Windows Vista and Windows 7 changed how domains are specified. There is no more drop-down list! The reasons why are complex, but essentially Microsoft made this change in the name of security.
In these newer versions of Windows, if you need to specify a different domain than the default, you must now manually type the domain name with your user name, using this syntax: DOMAIN \ USERNAME. Note the use of the backslash, which is usually above the Enter key on your keyboard. If the Log on to item is present and already shows the correct domain name, you can simply type your user name.
So, take a look at the most common screen you’ll see when you want to log on, which shows the user who last logged on and prompts for the password:
Notice the domain, JDFOXMICRO, is specified clearly here, but you can’t edit the domain or the user name just by clicking on it. You must click Switch User and then Other User, just like you do to use a different account even on a single-domain network.
Only now you will notice that the logon prompt shows the domain underneath the password box, where it says Log on to. On this screen, Windows Vista and Windows 7 always default to the domain that the computer itself is a member of, regardless of who logged in last. In this case, the computer is a member of the JDFOXMICRO domain, so that domain still shows here.
Notice that domain names and user names on Windows networks are not case-sensitive.

What Is A Domain User Account
Unlike a personal machine, a domain-connected PC doesn’t . Instead, the domain controller manages the logins. Using Microsoft’s Active Directory, a user management software, the network administrators can easily create new users and disable old ones. They can also add users to specific groups to allow access to private server folders.
With a domain account, you can sign into any computer that’s on the domain. You’ll start with a fresh account on that PC, but this enables you to use any computer in your company when needed. Thanks to domain accounts, ex-employees can’t sign back in either. If they try to log in with their old password, they’ll see a message that they were denied access.
The Windows login screen looks a bit different when you’re using a domain-connected PC. Instead of a local username, you’ll have to make sure you’re signing into the domain with your domain username. Thus, your login will look something like MyDomain\StegnerB01.
How Do You Know If Your Computer Is On A Domain
If you have a home computer, it’s very unlikely you’re on a domain. You could create a domain on your home network, but there’s not much use to doing so. But if you use a computer supplied by your work or school, it’s almost certainly on a domain.
To check if your computer is part of a domain, open the Control Panel and click the System entry. Look under the Computer name section. If you see a Workgroup entry with WORKGROUP or another name listed, your computer is not on a domain. Likewise, if you see Domain here, then your computer is on a domain.
These steps also allow you to find your domain name on your computer.

What Is A Domain
Windows domains provide network administrators with a way to manage a large number of PCs and control them from one place. One or more servers known as domain controllers have control over the domain and the computers on it.
Domains are generally made up of computers on the same local network. However, computers joined to a domain can continue communicating with their domain controller over VPN or Internet connection. This allows businesses and schools to remotely manage laptops they provide to their employees and students.
When a computer is joined to a domain, it doesnt use its own local user accounts. User accounts and passwords are managed on the domain controller. When you log into a computer on that domain, the computer authenticates your user account name and password with the domain controller. This means you can log in with the same username and password on any computer joined to the domain.
Network administrators can change group policy settings on the domain controller. Each computer on the domain will get these settings from the domain controller and theyll override any local settings users specify on their PCs. All the settings are controlled from a single place. This also locks down the computers. You probably wont be allowed to change many system settings on a computer joined to a domain.

Domain Names And Urls
The universal resource locator, or URL, is an entire set of directions, and it contains extremely detailed information. The domain name is one of the pieces inside of a URL. It is also the most easily recognized part of the entire address. When computer users type a web address directly into the field at the top of their browser window, it initiates a process of locating the page requested. To do so, the instructions contained inside the URL, including the domain name, must correctly point to that location. The IP address is a numerical code that makes this possible.

Registering Or Purchasing A Domain
While the common terminology is that you purchase a domain, in reality, its more like youre leasing it. You retain ownership of a domain by paying an annual fee. Depending on the domain and the registrar, which Ill talk about in a moment, those fees can be as low as five or six dollars a year, or much higher. Most registrars allow you to pre-pay at a discount for several years.
A registrar is a company authorized to register domains on your behalf and sell them to you. For example, one of the largest domain registrars is GoDaddy. I happen to use SimpleURL.
Not all registrars can sell all domains. For example, the popular .com, .net and .org domains are commonly available through most US-based registrars, but for foreign-based domains, such as .co.uk, .cn, .to and the like, youll often need to locate the registrar responsible for those top level domains, as theyre called, and register with them.
