与IPv4相比,IPv6具有许多优势。首先,IPv6解决了IP地址数量短缺的问题;其次,IPv6对IPv4协议中诸多不完善之处进行了较大的改进。其中最为显著的就是将IPSec集成到协议内部,从此IPSec将不再单独存在,而是作为IPv6协议固有的一部分贯穿于IPv6的各个领域。当然,IPSec的大规模使用
IPv6 has many advantages over IPv4. First of all, IPv6 solves the problem of a shortage of IP addresses. Secondly, IPv6 greatly improves many imperfections in the IPv4 protocol. One of the most significant is the integration of IPSec within the agreement, IPSec will no longer exist alone, but as an inherent part of the IPv6 protocol throughout all areas of IPv6. Of course, the massive use of IPSec
