What is DNS used for?
DNS servers
translate requests for names into IP addresses, controlling which server an end user will reach when they type a domain name into their web browser. These requests are called queries.

What is DNS explain with example?
D. N. S. (Domain Name System) The Internet's system for converting alphabetic names into numeric IP addresses. For example, when a Web address (URL) is typed into a browser, DNS servers
return the IP address of the Web server associated with that name.
What is a DNS and why is it important?
The Domain Name System (DNS) is
the phonebook of the Internet. Humans access information online through domain names, like nytimes.com or espn.com. Web browsers interact through Internet Protocol (IP) addresses. DNS translates domain names to IP addresses so browsers can load Internet resources.
What are two uses of DNS?
DNS serves other purposes in
addition to translating names to IP addresses. For instance, mail transfer agents use DNS to find the best mail server to deliver e-mail: An MX record provides a mapping between a domain and a mail exchanger; this can provide an additional layer of fault tolerance and load distribution.
Is DNS safe?
DNS is an old protocol, and it
was built without any integrated security. Several solutions have been developed to help secure DNS, including: Reputation Filtering: Like any other Internet user, most malware needs to make DNS requests to find the IP addresses of the sites that it is visiting.

The benefits of DNS are that domain names:- can map to a new IP address if the host's IP address changes.
- are easier to remember than an IP address.
- allow organizations to use a domain name hierarchy that is independent of any IP address assignment.
What is DNS problem in Internet?
DNS errors occur essentially
because you're unable to connect to an IP address, signaling that you may have lost network or internet access. DNS stands for Domain Name System.
What is DNS and its types?

Address Mapping record (A Record)—also known as a DNS host record, stores a hostname and its corresponding IPv4 address.

a third-party DNS service can both speed your internet activity and protect against tricky DNS-based attacks.
What are the types of DNS?

Domain Name Service which is used to convert alphabetic references into a server's IP address generally for hosting services.
What are the advantages and disadvantages of DNS?
DNS allows users to categorize and archive search terms without needing to remember IP addresses. All the domains are converted into IP addresses when the name is given to the search engines. Therefore, you don't need to memorize IP address for each and every site that you access frequently.
What causes a DNS problem?
Why does a DNS error occur? DNS errors occur essentially
because you're unable to connect to an IP address, signaling that you may have lost network or internet access. ... In other words, the DNS translates your web domain name into an IP address and vice versa.
