ALCATEL STC AUSTRALIA — MAC prefix identifies an IEEE registry assignment
Summary
- // what this is
- Alcatel STC Australia is registered to MAC prefix
00:80:39in the IEEE OUI database. When a device's MAC address begins with00:80:39, that block was registered by Alcatel STC Australia — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- A literal 00:80:39 match fixes the first-octet Group and Local bits at 0; matching covers 24 bits, with 24 suffix bits. Possible suffix values do not represent observed devices or shipments. RFC 7042 provides general MAC-prefix and bit-interpretation guidance.
About this vendor.
A MAC address beginning 00:80:39 matches the IEEE MA-L assignment to ALCATEL STC AUSTRALIA. The record identifies the prefix registrant; it does not establish the device, product, operator, or current legal identity behind a particular address. No device category or product catalog is established by the supplied records.
The prefix is 24 bits long, leaving 24 bits for possible suffix values: 16,777,216 combinations. These are possible address suffixes, not a count of devices, shipments, or observed addresses. For this literal prefix, the first octet is 00: its Group bit is 0 and its Local bit is 0. Changing either bit produces a different prefix; those bits do not vary within an exact 00:80:39 prefix match.
RFC 7042 describes 48-bit MAC identifiers as an initial OUI or longer assigned prefix followed by additional bits, and explains the Group and Local bits. Match all three prefix octets when checking this MA-L assignment. A match alone cannot establish deployment or security status.
- Registry match
00:80:39is assigned to ALCATEL STC AUSTRALIA under MA-L.- Device identification
- Unknown; the supplied evidence does not map a device category to this exact prefix.
- Matching boundary
- Compare the first 24 bits, or three octets; the remaining 24 bits have 16,777,216 possible values.
- First-octet bits
- Group bit 0 and Local bit 0 for this literal prefix.
