WHAI IS IP?
An IP address, or Internet Protocol address, is a numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. IP addresses serve two main functions: identifying the host or network interface and providing the location of the device in the network.
WHAT ARE DIFFERNET TYPES OF IP ADDRESS?
Public IP address*:* Public IP addresses are globally unique addresses assigned to devices directly connected to the internet. They are used to identify and communicate with devices over the internet. Websites, servers, and other internet-facing devices typically have public IP addresses.
Private IP address: Private IP addresses are used within private networks, such as local area networks (LANs) or intranets. These addresses are not directly accessible from the internet and are typically used for internal communication between devices within the same network. Private IP addresses are governed by specific address ranges defined in standards such as RFC 1918.
Static IP address: A static IP address is an address that remains constant and does not change over time. It is manually configured for a device and remains associated with that device until it is manually changed. Static IP addresses are often used for servers, routers, and other network infrastructure components that require a consistent address for accessibility.
Dynamic IP address*:* Dynamic IP addresses are assigned to devices by a DHCP (Dynamic Host Configuration Protocol) server on a temporary basis. These addresses can change over time as devices connect and disconnect from the network or as the DHCP server assigns new addresses. Dynamic IP addressing is commonly used for devices in residential and small business networks to efficiently manage available address space.
IPv4 address: IPv4 (Internet Protocol version 4) addresses are 32-bit numerical addresses used to identify devices on a network. Due to the limited number of available IPv4 addresses, IPv6 has been developed to provide a much larger address space.
IPv6 address*:* IPv6 (Internet Protocol version 6) addresses are 128-bit numerical addresses designed to replace IPv4 addresses. IPv6 addresses offer a significantly larger address space, allowing for the proliferation of internet-connected devices without the concerns of address exhaustion.
