Convert a Livewire channel number to its multicast IP address — Standard, Backfeed, Surround, and AES67 stream types
Livewire Multicast Address Calculator
Livewire encodes channel numbers directly into multicast IP addresses. Each stream type uses a different base address range.
Address Range Reference
| Stream Type | Base Address | Range | Notes |
|---|---|---|---|
| Standard | 239.192.0.0 | ch 1–32767 | Primary program audio |
| Backfeed | 239.193.0.0 | ch 1–32767 | Return feeds to studios |
| Backfeed Livestream | 239.195.0.0 | ch 1–32767 | Low-latency return streams |
| Surround / 5.1 | 239.196.0.0 | ch 1–32767 | 8-channel surround audio |
The last two octets encode the channel number. Ch 27 = 239.192.0.27 |
Ch 256 = 239.192.1.0 | Ch 1212 = 239.192.4.188.
