(The seventh bit will be 0, make it a 1). Note: The MAC address 11:22:33:44:55:66 will be used for the following examples.

My servers and the machines where I do my troubleshooting are running Windows. Take the MAC address and convert the first octet from hexadecimal into binary. Customer IPv4: IP: using bits use your public IPv4 address (PPP: your own, not the peer address) and the bits value from the ISP or 32 for 6to4. Provider prefix IPv6: / Use 2002::/16 for 6to4 and whatever you ISP gave you for 6rd. How can I determine which device on my network has this IPv6 address? IPv6 Address: Please use hexadecimal notation with the relevant 32 bits to the far right. We update MAC address lookup database as soon as we have new information from the IEEE database and Wireshark manufacturer database. What you have is an address using privacy extensions or random generation. An IPv6 address generated from a MAC address will have ff:fe in the middle of the Interface ID portion of the address, but that address has 70:16 there. None of the OUI lookup tools recognize it and it doesn't appear in my IPv4 DHCP leases. That address, fe80::1d81:b870:163c:5845, is not an IPv6 address generated from a MAC address. I tried that and get the MAC 13:3d:d9:85:94:3b. I attempted a crash course in IPv6 and learned that the fe80 prefix means the address is link-local and I can supposedly derive the MAC address from the address. But this network doesn't have a IPv6 DHCP server and arp doesn't seem to speak IPv6. Failing that, I'd ping it, then run arp -a to get its MAC address, which at least gives me the manufacturer. With an IPv4 device I can look at my DHCP leases to get the device name. convert the first octet from hexadecimal to binary: 52 -> 01010010. reformat to IPv6 notation 5274:f2ff:feb1:a87f. I ran tracert and determined it's on the local link and currently online: Tracing route to fe80::113d:d91e:e685:943b over a maximum of 30 hopsġ 9 ms <1 ms 1 ms fe80::113d:d91e:e685:943b Conversion step by step from a MAC address (48 bits) to a IPv6 address (128 bits): take the mac address: 52:74:f2:b1:a8:7f. I'm a noob when it comes to IPv6 and I've got a machine on my 60+ node network that is part of a malware-spewing botnet. Here’s how to figure out what MAC address your IP address maps to: We convert your IP address to binary: decimal: 239.192.0.1 binary: 11101111 11000000 00000000 00000001. Finally after four days a matching DNS lookup request was made, but to my dismay the request came from the address fe80::113d:d91e:e685:943b. I need to find that device and deal with it, so I enabled logging on my DNS server. Convert a mac address between dot notation, bit-reversed, hexadecimal and more Paste MAC Address below. My ISP notified me that a device on my network performed a DNS lookup for one of the C&C servers taken offline in the recent law enforcement action against the Avalanche botnet. I've avoided IPv6 until now, but my blissful ignorance must end.
