MAC address vendor
SnapAV MAC prefix assignments: vendor identity only
Primary prefix
D4:6A:91
Block
MA-L
Summary
- // what this is
- SnapAV is registered to MAC prefix
D4:6A:91and 1 more in the IEEE OUI database. When a device's MAC address begins withD4:6A:91, that block was registered by SnapAV — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- Both assigned prefixes are 24 bits long, leaving 24 suffix bits (16,777,216 possible suffix values per prefix). For each exact prefix, the first-byte Group and Local bits are fixed at 0; changing either bit produces a different prefix. A match indicates registry assignment only, not a particular deployed device or device count.

About this vendor.
Updated · Confidence: High · 2 sources · How this page is checked
A MAC address beginning with either D4:6A:91 or 14:3F:C3 matches an IEEE MA-L assignment registered to SnapAV; the registry record alone does not identify a device type or product. Both assignments are 24-bit prefixes, leaving 24 bits in the address after the prefix.
RFC 7042 describes the first three octets of a 48-bit MAC identifier as an OUI and explains the Group and Local bits. For these exact prefixes, both bits are zero in the first octet, so they are fixed as unicast and globally administered indicators in the prefix. A captured address matching one of these prefixes establishes an assignment match, not deployment, vendor of a particular device, or security status.
- Identification
- SnapAV is the organization named on both IEEE MA-L records; no device category is established.
- Matching prefixes
D4:6A:91and14:3F:C3are 24-bit prefixes; match the first three octets.- Address bits
- For each exact prefix, the first-byte Group bit is 0 and Local bit is 0. Changing either bit yields a different prefix.
- Suffix space
- Each prefix leaves 24 bits, allowing 16,777,216 possible suffix values; this is not a count of devices or shipments.
