IP
An IP address, or Internet Protocol address, is a series of numbers that identifies any
device on a network. Computers use IP addresses to communicate with each other both
over the internet as well as on other networks
Internet Protocol Address (IP address) is a numerical label assigned to each device connected to a
computer network that uses the internet protocol for communication
The Internet Protocol (IP) is a protocol, or set of rules, for routing and addressing packets
of data so that they can travel across networks and arrive at the correct destination. Data
traversing the Internet is divided into smaller pieces, called packets.
There are four types of IP addresses: public, private, static, and dynamic.
IP v4 VS IP v6
Class Range
, Lowest Highest
A 0.0.0.0 127.255.255.255
B 128.0.0.0 191.255.255.255
C 192.0.0.0 223.255.255.255
There are five classes of subnetworks: Class A, Class B, Class C, Class D, and
Class E. Each class relates to a specific range of IP addresses. Classes A, B, and C
are used the most often by different networks.
Subnet classes are made unique by the number of bits their IP addresses have
dedicated to a network and the number of bits dedicated to hosts. They each have a
default subnet mask. Classes can be identified by the number in the first octet of
their address.
Class A: First Octet Value 0-126
Class B: First Octet Value 128-191
Class C: First Octet Value 192-233
Class D: First Octet Value 224-239
Class E: First Octet Value 240-255
DNS -Domain Name system
What DNS means?
Domain Name System
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).
Domain Name System (DNS)
The Domain name systems (DNS) is the phone book of the internet. Humans access information
online through domain names, like bbc.com or Microsoft.com. Web browsers interact through
internet protocol (IP) addresses. DNS translates domain name to IP addresses so browsers can load
internet resources.
DNS record
DNS records (aka zone files) are instructions that live in authoritative DNS
servers and provide information about a domain including what IP address is
associated with that domain and how to handle requests for that domain.
These records consist of a series of text files written in what is known as DNS
syntax.
