A MAC address 00:0C:29:0C:47:D5 is turned into a 64-bit EUI-64 by > inserting FF:FE in the middle: 00:0C:29:FF:FE:0C:47:D5. When this EUI-64 is > used to form an IPv6 address it is modified:[1] the meaning of the > Universal/Local bit (the 7th most significant bit of the EUI-64, starting > from 1) is inverted, so that a 1 now means Universal. To create an IPv6 > address with the network prefix 2001:db8:1:2::/64 it yields the address > 2001:db8:1:2:020c:29ff:fe0c:47d5 (with the underlined U/L (=Universal/Local) > bit inverted to a 1, because the MAC address is universally unique)." > The API should return this address in the ip6address field for a NIC in Basic > Networking. > End-Users can use this, but it can also be used internally by Security > Grouping to program rules. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
