IP Multicast and IP Address Range
This section provides a quick introduction of IP Multicast communication and IP address range, from 18.104.22.168 to 22.214.171.124, reserved for multicast.
MS08-001 vulnerability is around Windows' handling of the IGMP and MLD protocols, which
are used to control multicast traffic over the network. So let's learn some basics about multicast
communication in this section first.
What Is Multicast? Multicast is a network communication technology for the delivery of information
to a group of destinations simultaneously using the most efficient strategy.
If multiple destinations are on a single physical network, only a single copy of the message needs to be
transferred on that network.
On the Internet network, multicast is also called IP Multicast. It uses a multicast group address
to link message sources and receivers together.
A multicast group address is any IP address in the IP address range from 126.96.36.199 to 188.8.131.52.
This range of IP addresses are reserved for IP Multicast communications only.
Some of reserved IP addresses are registered for special purposes:
- 184.108.40.206 - Base address (reserved)
- 220.127.116.11 - The All Hosts multicast group that contains all systems on the same network segment
- 18.104.22.168 - The All Routers multicast group that contains all routers on the same network segment
- 22.214.171.124 - The Open Shortest Path First (OSPF) AllSPFRouters address. Used to send Hello packets to all OSPF routers on a network segment
- 126.96.36.199 - The OSPF AllDRouters address. Used to send OSPF routing information to OSPF designated routers on a network segment
- 188.8.131.52 - The RIP Version 2 group address. Used to send RIP routing information to all RIP v2 routers on a network segment
- 184.108.40.206 - EIGRP group address. Used to send EIGRP routing information to all EIGRP routers on a network segment
- 220.127.116.11 - Virtual Router Redundancy Protocol
- 18.104.22.168 - IGMP Version 3 (Internet Group Management Protocol)
- 22.214.171.124 - Hot Standby Router Protocol Version 2
- 126.96.36.199 - Multicast DNS address
- 188.8.131.52 - Cisco-RP-Announce address
- 184.108.40.206 - H.323 Gatekeeper discovery address
