Whats Is IP Address ?
An IP address (Internet Protocol address) is a unique numerical label assigned to every device connected to a computer network that uses the Internet Protocol for communication. It acts as a identifier for a device and helps in routing of data packets to their destination over the network.
There are two types of IP addresses: IPv4 (32-bit) and IPv6 (128-bit). An IPv4 address is written in the format x.x.x.x, where x is a number between 0 and 255, while an IPv6 address is written in hexadecimal format with colons separating each 16-bit block.
IP addresses are important because they enable computers to send and receive data over the internet and allow the creation of a global network infrastructure.
IPv6 Explaination
IPv6 (Internet Protocol version 6) is the most recent version of the Internet Protocol (IP), the communications protocol that provides an identification and location system for computers on networks and routes traffic across the Internet. It was designed to replace the older IPv4, which is reaching its limit in terms of the number of available addresses.
The main difference between IPv4 and IPv6 is the length of their addresses. IPv4 uses 32-bit addresses, which allows for approximately 4.3 billion unique addresses, while IPv6 uses 128-bit addresses, providing an virtually unlimited number of addresses. This increase in the number of available addresses allows for the growth of the Internet and the increased use of connected devices.
IPv6 also includes several new features and improvements over IPv4, including a simplified header format, improved support for mobility and security, and automatic configuration of addresses. These improvements make IPv6 more efficient, scalable, and secure than IPv4.
Adoption of IPv6 has been slow, but it is increasingly being deployed by Internet Service Providers (ISPs) and corporations around the world. This is due to the growing shortage of IPv4 addresses, as well as the need for a more efficient and secure communication protocol.
In summary, IPv6 is the next generation of the Internet Protocol that provides a larger number of unique addresses and improved features for a more efficient, scalable, and secure communication network. Its deployment is crucial for the continued growth and development of the Internet.
Whats is IPv4 ?
IPv4 (Internet Protocol version 4) is the fourth version of the Internet Protocol, the primary communication protocol used for transmitting data over the internet. It was first defined in 1981 and has since been widely adopted as the standard for internet communication.
IPv4 uses 32-bit addresses, which allows for approximately 4.3 billion unique addresses. Each address is written as four numbers separated by dots (e.g., 192.168.1.1). The address acts as a unique identifier for a device connected to the internet, allowing data to be sent and received between devices.
One of the key features of IPv4 is its hierarchical structure, which allows for the efficient routing of data packets. The address is divided into different parts, with the first part indicating the network and the remaining parts indicating the host within the network. This structure allows for efficient and scalable routing of data over the internet.
Despite its widespread use, IPv4 has some limitations. The limited number of unique addresses is a major issue, as more and more devices are being connected to the internet. This has led to the depletion of available addresses and the development of IPv6, which provides a much larger number of unique addresses.
In conclusion, IPv4 is an essential component of the internet and has been crucial in the development and growth of the internet as we know it today. However, due to its limitations, it is gradually being replaced by IPv6, which offers a larger number of unique addresses and improved features.
Class division of IP address
Class Type | Range IP Address | ||||||
A | 1.0.0.0 - 126.255.255.255 | ||||||
B | 128.0.0.0 - 191.255.255.255 | ||||||
C | 192.0.0.0 - 223.255.255.255 | ||||||
D | 224.0.0.0 - 239.255.255.255 | ||||||
E | 240.0.0.0 - 255.255.255.255 |
IP addresses are divided into different classes, based on their first few bits, to allow for efficient routing of data packets over the internet. There are five classes of IP addresses: Class A, B, C, D, and E.
Class A IP addresses have their first bit set to 0 and their first octet (the first eight bits) in the range of 1 to 126. This allows for 126 possible Class A networks, each with a maximum of 16,777,214 unique addresses. Class A addresses are typically assigned to very large organizations, such as corporations and governments, which require a large number of unique addresses for their devices.
Class B IP addresses have their first two bits set to 10 and their first octet in the range of 128 to 191. This allows for 16,384 possible Class B networks, each with a maximum of 65,534 unique addresses. Class B addresses are typically assigned to mid-sized organizations that require a moderate number of unique addresses for their devices.
Class C IP addresses have their first three bits set to 110 and their first octet in the range of 192 to 223. This allows for 2,097,152 possible Class C networks, each with a maximum of 254 unique addresses. Class C addresses are typically assigned to small organizations or individual users that only require a few unique addresses for their devices.
Class D IP addresses have their first four bits set to 1110 and are reserved for multicast addressing. Multicast addressing allows for the efficient transmission of data to a group of devices, rather than to each device individually.
Class E IP addresses have their first four bits set to 1111 and are reserved for future use or experimental purposes.
In conclusion, IP addresses are divided into different classes to allow for efficient routing of data packets over the internet. Each class has a specific range of values and is assigned to different types of organizations based on their unique address requirements.
