IANA has assigned several ranges of multicast IP addresses for specific types of reasons:
- Permament multicast groups: 224.0.0.0 - 224.0.1.255
- Adresseses used with Source-Specific Multicast (SSM): 232.0.0.0 - 232.255.255.255
- GLOP addressing: 233.0.0.0 - 233.255.255.255
- Private multicast addresses: 239.0.0.0 - 239.255.255.255
- Transient multicast addresses: 224.0.2.0 - 231.255.255.255, 234.0.0.0 - 238.255.255.255
