METHOD AND AN APPARATUS FOR CREATING A UNIQUE IPV6 ADDRESS BY USING AN INTERFACE ID, ESPECIALLY CONCERNED WITH MINIMIZING THE POSSIBILITY THAT IPV6 ADDRESSES ARE DUPLICATED WITH EACH OTHER

摘要

PURPOSE: A method and apparatus for creating an IPv6 address using an interface ID is provided to minimize the possibility of duplication by creating a unique IPv6 address by using an interface ID. CONSTITUTION: In the case of a link local address(430), an IPv6 address is created as a unique ID bit stream, extracted as much as 54 bits from the uppermost bit of a unique ID value, is combined with a 54-bit zero field(432) from the 11th bit to the 64th bit. In the case of a site local address(440), an IPv6 address is created as a unique ID bit stream, extracted as much as 38 bits from the uppermost bit of a unique ID value, is combined with a 38-bit zero field(442) from the 11th bit to the 48th bit. In the case of a global address(450), an IPv6 address is created as a unique ID bit stream, extracted as much as (64-n) bits from the uppermost bit of a unique ID value, is combined with a (64-n)-bit zero field(452) from the n+1th bit to the 64th bit.
