但IPv 6与IPv4无法兼容，用IPv6地址就无法进入使用IPv4地址的网站。

But IPv6 and IPv4 are not compatible, so anyone working with a new IPv6 address would not be able to access Web sites using old IPv4 addresses.

大约有40亿个IPv4地址，二进制的IP地址的长度是32位，可以有这么多不同的组合。

There are about 4 billion IPv4 addresses, because the length of the addresses in binary form — 32 bits — allows for that many possible unique combinations.

更多的地址IPv 6使用128位地址而不是目前的32位地址，这样可用IP地址的数量会急剧增加。

IPv6 USES 128-bit addresses rather than the current 32-bit addresses allowing for an exponential increase in the number of available IP addresses.

It imports it into our database and does some fancy indexing as we'll call it later in the term to make searches more efficient.

将它导入到我们的数据库中，并进行一些变址,这将在后期会提到,它可以使查找更高效。
