Vendor ethernet mac address lookup serial number#
VLANs still copy that base address - as normal - and are not unique among VLANs on the same trunk.The MAC address is the unique serial number burned into each network adapter that differentiates the network card from all others, just as your house number is unique on your street and identifies your home from all others. With this setting ON, “c1-4a” is replaced by a unique number for that Ethernet interface. With this setting off, the shared address will be 10-00-00-c1-4a-xx. It’s the 10-00-00 address, +1 in the first byte, following standard multicast assignment rules. If you’re a Clavister customer, that’s likely HA Cluster Heartbeats you’re seeing - it should be a handful every second. The last (sixth) byte is the cluster ID in hexadecimal. If you’re a Clavister customer, that’s likely a HA cluster shared MAC address that you are seeing. Clavister HA shared (virtual) MACs 10-00-00? If you want the Official Source, it’s - but the wireshark tables also contain unassigned-but-commonly-found addresses. There’s many that are poorly updated or pull from bad sources. X3 x7 xa xf = multicast belonging to locally-assigned Good lookup tools X1 x5 x9 xd = multicast, should belong to above The 4 lowest bytes are taken from the IPv6 address. This means that several valid IPv4 multicast addresses map to the same Ethernet addresses. The final bytes are taken directly from the lowest 23 bits (aka 3 bytes minus highest 1 bit) of the IPv4 multicast address. This ought to be an actual IEEE OUI - 01-00-5e-xx-xx-xx = IPv4 multicast First byte is x0, x4, x8, xc = you can look it up! Subtracting 2 from the first byte MAY get you the vendor, depending on what practice the local admins follow. These are not registered with IEEE - you are supposed to assign them “locally”, with varying interpretations of “local”. First byte not divisible by 4 = locally-configured Rounding down to a multiple of 4 ( = subtracting 1 or 3 ) from the first byte MAY get you the vendor, depending on application. These are typically never used as source address, only destination address. The first 3 bytes are often referred to as the “MAC Vendor field” or “IEEE OUI”, though note that OUI:s are also used for non-Ethernet things.
