#Mac address convert to ipv6 Offline#

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. 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. ipaddr () works with both IPv4 and IPv6 addresses in various forms. It can operate on strings or lists of items, test various data to check if they are valid IP addresses, and manipulate the input data to extract requested information. With an IPv4 device I can look at my DHCP leases to get the device name. ipaddr () is a Jinja2 filter designed to provide an interface to the netaddr Python package from within Ansible. 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 The IEEE manages allocation of MAC addresses, originally known as MAC-48 and which it now refers to as EUI-48 identifiers. 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. Description This converter was implemented per Dave Russell’s suggestion as a follow up to the MAC address to IPv6 link-local address online converter. I've avoided IPv6 until now, but my blissful ignorance must end. The converter It can also be addressed directly via: for all your API needs.
