MAC address vendor
Suzhou Pairlink Network Technology MAC prefixes: registry assignment identified
Primary prefix
EC:C5:7F
Block
MA-L
Summary
- // what this is
- Suzhou Pairlink Network Technology is registered to MAC prefix
EC:C5:7Fand 2 more in the IEEE OUI database. When a device's MAC address begins withEC:C5:7F, that block was registered by Suzhou Pairlink Network Technology — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- These records show IEEE registry assignments. Prefix length determines the suffix space: 24 bits for each MA-L assignment and 20 bits for the MA-M assignment. All three prefixes have Group and Local bits set to zero. The suffix counts describe possible address values, not observed devices. RFC 7042 describes the Group and Local bit meanings and MAC prefix structure.

The IEEE registry lists Suzhou Pairlink Network Technology for EC:C5:7F, 10:C2:83, and F0:AC:D7:6/28. The supplied records do not identify device types associated with these assignments.
The two MA-L prefixes cover 24 bits each, leaving 24 suffix bits; the MA-M prefix covers 28 bits, leaving 20 suffix bits. Each has Group and Local bits set to zero. The corresponding suffix spaces contain 16,777,216 values for each MA-L prefix and 1,048,576 for the MA-M prefix. These are address-space counts, not observed device counts.
