Internet Group Management Protocol (IGMP). Computer and Network Examples
The Internet Group Management Protocol (IGMP) is a communication protocol of the multicast transfer data in the IP networks. IGMP is used by routers and IP hosts for organizing the network devices in groups.This example was created in ConceptDraw PRO using the Computer and Networks solution from the Computer and Networks area of ConceptDraw Solution Park. It shows the architecture of the network for delivering a multicast service using IGMP.

"A subnetwork, or subnet, is a logically visible subdivision of an IP network. The practice of dividing a network into two or more networks is called subnetting.
All computers that belong to a subnet are addressed with a common, identical, most-significant bit-group in their IP address. This results in the logical division of an IP address into two fields, a network or routing prefix and the rest field or host identifier. The rest field is an identifier for a specific host or network interface.
The routing prefix is expressed in CIDR notation. It is written as the first address of a network, followed by a slash character (/ ), and ending with the bit-length of the prefix. ...
The IPv6 address specification 2001:db8::/ 32 is a large address block with 296 addresses, having a 32-bit routing prefix. In IPv4 the routing prefix is also specified in the form of the subnet mask, which is expressed in quad-dotted decimal representation like an address. ...
Traffic between subnetworks is exchanged or routed with special gateways called routers which constitute the logical or physical boundaries between the subnets.
The benefits of subnetting vary with each deployment scenario. In the address allocation architecture of the Internet using Classless Inter-Domain Routing (CIDR) and in large organizations, it is necessary to allocate address space efficiently. It may also enhance routing efficiency, or have advantages in network management when subnetworks are administratively controlled by different entities in a larger organization. Subnets may be arranged logically in a hierarchical architecture, partitioning an organization's network address space into a tree-like routing structure." [Subnetwork. Wikipedia]
