Who invented the DNS protocol?
Paul V. Mockapetris
When was DNS invented?
What is the purpose of DNS?
Domain Name Servers (DNS) are the Internet’s equivalent of a phone book. They maintain a directory of domain names and translate them to Internet Protocol (IP) addresses. This is necessary because, although domain names are easy for people to remember, computers or machines, access websites based on IP addresses.
What is DNS Example?
DNS – Domain Name System
The Internet however, is really based on IP addresses. Every time you use a domain name, therefore, a DNS service must translate the name into the corresponding IP address. For example, the domain name www.example.com might translate to 198.105. 232.4.
Is DNS a protocol?
(Although many people think “DNS” stands for “Domain Name Server,” it really stands for “Domain Name System.”) DNS is a protocol within the set of standards for how computers exchange data on the internet and on many private networks, known as the TCP/IP protocol suite.
What was used before DNS?
Before the Internet and the DNS
In 1958, under the president Eisenhower, ARPA (Advanced Research Projects Agency) started. It was a big step for the American science and a response to the Soviet achievements (Sputnik 1, 1957). In the 60s ARPA was getting stronger and bigger.
Why do we need IPv6?
The Internet has experienced a phenomenal increase of devices accessing the Internet. Because of this increase, IPv4 addresses are running out. The solution is for IPv6 to accommodate this increased demand by providing a much larger address space, along with improved traffic routing and better security.
How many types of DNS are there?
3 types of DNS servers—DNS Resolver, DNS Root Server and Authoritative Name Server. 10 types of common DNS records—including A, AAAA, CNAME, MX and NS.
What does DNS stand for in government?

What layer is DNS?
In OSI stack terms, DNS runs in parallel to HTTP in the Application Layer (layer 7). DNS is in effect an application that is invoked to help out the HTTP application, and therefore does not sit “below” HTTP in the OSI stack. DNS itself also makes use of UDP and more rarely TCP, both of which in turn use IP.
What are two uses of DNS?
It is mainly used to convert human meaningful names (domain name) to computer meaningful name (IP address) in Internet. This is because computers can only recognize IP addresses. It allows you to use internet more easily by allowing you to specify a meaningful name on your web browser instead of using IP address.
What ports do DNS use?
DNS is provided over intranet and internet servers with different port numbers.
- TCP or UDP. DNS can use both transmission protocols TCP and UDP.
- TCP Port 53. One of the used DNS port is TCP Port 53.
- UDP Port 53. Most known and popular usage protocol of DNS is UDP 53.
- DNSSEC Port Number.
What is TCP IP in networking?
TCP/IP stands for Transmission Control Protocol/Internet Protocol, which is a set of networking protocols that allows two or more computers to communicate. The Defense Data Network, part of the Department of Defense, developed TCP/IP, and it has been widely adopted as a networking standard.
What is meant by IP address?
An IP address, or simply an “IP,” is a unique address that identifies a device on the Internet or a local network. It allows a system to be recognized by other systems connected via the Internet protocol. There are two primary types of IP address formats used today — IPv4 and IPv6.
What is DHCP in networking?
Dynamic Host Configuration Protocol (DHCP) is a protocol for assigning dynamic IP addresses to devices on a network. With dynamic addressing, a device can have a different IP address every time it connects to the network.
