What is the difference between domain and DNS?
Your domain name, like www.dnsmadeeasy.com, is essentially the face of your IP address, 123.45.
DNS is the framework of the internet that connects a user who types in a domain name to their desired site.
Computers can’t communicate using domain names, so instead they find each other through the use of IP addresses..
What are the three domains of the DNS?
DNS is a TCP/IP protocol used on different platforms. The domain name space is divided into three different sections: generic domains, country domains, and inverse domain.
What is the purpose of DNS?
DNS translates domain names to IP addresses so browsers can load Internet resources. Each device connected to the Internet has a unique IP address which other machines use to find the device. DNS servers eliminate the need for humans to memorize IP addresses such as 192.168.

What you need to know about DNS?
DNS is simply that — it allows computers to translate human readable things, like a URL, into an IP address. If you’re not clear on what an IP address is, think of it as a phone number in the phone book. … The phone book provides names so you know who you’re calling. DNS does the same thing.
What is a NIS domain?
An NIS domain is a collection of systems that are logically grouped together. A group of hosts that share the same set of NIS maps belong to the same domain. The hosts are usually grouped together in the domain for a common reason; for example, when working in the same group at a particular location.
Is NIS still used?
NIS (nee YP) appears to be immortal. It’s almost 30 years old, and it is still in widespread use today.
Why do we need NIS?
We use the Linux NIS server (Network Information Service) for sharing critical data stored in flat files between systems on a network. It is often ideal to have a shared repository (such as NIS) for storing users and groups information instead of storing them in flat files like /etc/passwd.
What are the two types of DNS?
What are the different types of DNS server? All DNS servers fall into one of four categories: Recursive resolvers, root nameservers, TLD nameservers, and authoritative nameservers.
What is DNS Example?
DNS, or the Domain Name System, translates human readable domain names (for example, www.amazon.com) to machine readable IP addresses (for example, 192.0. 2.44).
What is DNS and its types?
DNS servers create a DNS record to provide important information about a domain or hostname, particularly its current IP address. The most common DNS record types are: Address Mapping record (A Record)—also known as a DNS host record, stores a hostname and its corresponding IPv4 address.
What is a DNS for a domain?
The Domain Name System (DNS) is a central part of the internet, providing a way to match names (a website you’re seeking) to numbers (the address for the website). … DNS syncs up domain names with IP addresses enabling humans to use memorable domain names while computers on the internet can use IP addresses.
