将IPv4转换为IPv6 [英] Convert IPv4 to IPv6

问题描述

是否有将IPv4转换为IPv6的直接方式？


我认为这只是一个问题将32位转换为128位，（通过

添加96个前导0），但在某些/大多数情况下这似乎不正确。


例如， 127.0.0.1，（IPv4 localhost），不转换:: 1，（IPv6

localhost）


所以，是否有函数/脚本/技术将IPv4转换为IPv6？


谢谢

我不知道数学，因为我不再处理网络问题了。你可以尝试将IP4分成它的八位字节然后应用数学，然后重新组装。

查看IPv6 RFC和/或其Wikipedia条目。 IIRC有一个

地址范围，用于映射旧的IPv4地址。

这是一个完全不同的编号系统。

是的，我看过它，我的印象是IPv6是IPv4的继承者

所以32位保留给允许向后兼容。

我不会完全忘掉''完全''。

Hi,

is there a straight forward way of converting IPv4 to IPv6?

I thought that it was just a matter of converting 32 bits to 128 bits, (by
adding 96 leading 0s), but that does not seem right in some/most cases.

For example, 127.0.0.1, (IPv4 localhost), does not convert ::1, (IPv6
localhost)

so, is there a function/script/technique to convert IPv4 to IPv6?

Thanks

Simon

I don''t know the math as I don''t deal with networking anymore. You
could try splitting IP4 into it''s octets and apply the math like that
then reassemble.

Have a look at the IPv6 RFC and/or its Wikipedia entry. IIRC there''s an
address range reserved for mapping the old IPv4 addresses.

It''s a totally different numbering system.

Yes, I had a look at it, and my impression was that IPv6 was the successor
of IPv4 so 32bits had been reserved to allow for backward compatibilities.

I wouldn''t go as far as asying ''totally''.

127.0.0.1 -01111111.00000000.00000000.00000001 ->
0111111100000000:0000000000000001 - 7f00:0001
