The Internet Group Management Protocol (IGMP) is a protocol that allows several devices to share one IP address so they can all receive the same data. IGMP is a network layer protocol used to set up multicasting on networks that use the Internet Protocolversion 4 (IPv4). Specifically, IGMP allows devices to join a multicasting group.
Multicasting is when a group of devices all receive the same messages or packets. Multicasting works by sharing an IP address between multiple devices. Any network traffic directed at that IP addresswill reach all devices that share the IP address, instead of just one device. This is much like when a group of employees all receive company emails di...
Computers and other devices connected to a network use IGMP when they want to join a multicast group. A router that supports IGMP listens to IGMP transmissions from devices in order to figure out which devices belong to which multicast groups. IGMP uses IP addresses that are set aside for multicasting. Multicast IP addresses are in the range betwee...
The IGMP protocol allows for several kinds of IGMP messages: 1. Membership reports: Devices send these to a multicast router in order to become a member of a multicast group. 2. "Leave group" messages: These messages go from a device to a router and allow devices to leave a multicast group. 3. General membership queries: A multicast-capable router ...
IGMP is a network layer protocol, and only networking devices that are aware of the network layer can send and receive messages. A router operates at the network layer, while a network switchmay only be aware of layer 2, also known as the data link layer. As a result, a switch may be unaware of which network devices are part of multicast groups, an...
IPv4 and IPv6 are two different versions of the Internet Protocol (IP). IPv6 is more modern, but IPv4 is still in wide use. In IPv6, Multicast Listener Discovery (MLD) is the protocol for multicasting, not IGMP.
Jun 14, 2024 · Unlike SMS texts, RCS messages are routed over a mobile data connection or Wi-Fi link, with SMS functioning as a fallback.
You can report spam or scam texts directly to your mobile phone provider free of charge by forwarding the text message to 7726. When you report a text you may get an automated response thanking you for the report and giving you further instructions if needed.

Jul 6, 2020 · IGMP (Abbreviation for Internet Group Management Protocol) is used by the TCP/IP protocol suite to achieve dynamic multicasting. It allows a host to advertise its group membership to neighbouring switches and routers. Hosts identify group memberships by sending IGMP messages to their local multicast router. Under IGMP, routers listen to IGMP ...
