How can I determine which device on my network has this IPv6 address? None of the OUI lookup tools recognize it and it doesn't appear in my IPv4 DHCP leases. Convert the left side of your MAC address into binary format. Add FFFE fixed hexadecimal part to the middle of the mac address. I tried that and get the MAC 13:3d:d9:85:94:3b. MAC address (Media Access Control address) is a unique identifier assigned to network interfaces for communications on a physical network. Follow the steps in the below steps to produce an IPv6 Interface ID from this MAC address: Divide this MAC address into two part. 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. 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 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. 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.

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.
