administrators have not expected this risk caused by IPv6.
Secondly, when enterprises welcome IPv6, IT management becomes more difficult. James Lyne, director of Sophos technical strategy, told reporters that companies that are not interested in IPv6 traffic want to set up clear rules to strictly block IPv6 packets. However, IT administrators must know "How to Talk to IPv6" before writing corresponding rules to handle the protocol.
