What are the features of IP address?

An IP address, or Internet Protocol address, is a unique identifier assigned to each device connected to a network. The main features of an IP address include its format, which is typically either IPv4 or IPv6. IPv4 addresses are 32-bit numerical labels written in decimal format as four octets separated by periods (e.g., 192.168.0.1). IPv6 addresses are 128-bit hexadecimal labels separated by colons (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334). Each IP address contains a network portion and a host portion, allowing devices to be identified within their network and facilitating routing.

Internet addressing refers to the assignment of unique identifiers to devices connected to the internet or any other network, allowing them to communicate. Its features include the use of hierarchical addressing, which helps in efficient routing and management of IP addresses. Internet addressing can be public or private, with public addresses being unique and globally routable, while private addresses are used within local networks and are not routable on the global internet. This system ensures proper data delivery to the correct destination.

The properties of an IP address include its uniqueness within the assigned network, ensuring no two devices share the same address. IP addresses are hierarchical, comprising network and host segments, which support scalable network design and efficient routing. They are either static or dynamic, with static IPs being fixed and dynamic IPs assigned by DHCP servers. Furthermore, IP addresses can be publicly accessible or reserved for private networks, facilitating both global and local communication.

The primary functions of an IP address are identification and location of devices on a network. It ensures devices can be uniquely identified for communication purposes. Additionally, IP addresses facilitate routing by providing the necessary information for data packets to reach their intended destinations across interconnected networks. This role in routing also includes ensuring that data packets are sent through the most efficient path from source to destination.

The two main features of the IP protocol are connectionless communication and best-effort delivery. Connectionless communication means that each data packet, or datagram, is treated independently, and packets can take different paths to reach the destination without establishing a dedicated connection. Best-effort delivery indicates that the IP protocol does not guarantee packet delivery, ordering, or error correction, leaving these tasks to higher-level protocols like TCP to handle.
