Instead of four dotted decimal digits, IPv6 USES 128 bits c.f. IPv4's which are represented as groups of hex like 1234:5678:90ab: cdef: 1234:5678:90ab: cdef.
与4个点分十进制不同的是，IPv 6使用了128位，表示为1234：5678：90ab：cdef： 1234： 5678： 90ab： cdef这样一组数字。
An IP address is -- in IP version 4 -- a 32-bit number, typically represented in dotted-decimal notation (such as 10.0.0.1).
IP地址（IP版本4）是一个32 位数，通常以点分十进制符号（如 10.0.0.1）表示。
