+## Note: MAC address
+
+1. It's a locally administered address (the second bit in the first byte is set to 1)
+2. It's a unicast address (the first bit in the first byte is set to 0)
+
+Your previous MAC address `d5:62:40:43:af:06` starts with `d5`, which in binary is `11010101`. The first bit being `1` makes it a multicast address, which most network interfaces won't accept for their own hardware address.
+
+For a valid unicast, locally administered MAC address, the first byte should follow this pattern:
+- Bit 0 (least significant): 0 for unicast (individual), 1 for multicast
+- Bit 1: 0 for globally unique, 1 for locally administered
+
+So valid first bytes for a locally administered unicast MAC would include:
+- `02` = `00000010` (locally administered, unicast)
+- `06` = `00000110`
+- etc.
