IPv4 / IPv6 轉換器 — 免費線上工具

什麼是 IPv4 / IPv6 轉換器？

免費線上 IPv4/IPv6 轉換工具。在 IPv4 與 IPv6 位址表示法之間轉換。

為什麼要使用 IPv4 / IPv6 轉換器？

Four conversion modes for all common IP format transformations
IPv4-mapped (::ffff:x.x.x.x) and IPv4-compatible formats
IPv6 expansion with full 8-group zero padding
IPv6 compression with :: zero-group collapsing
Embedded IPv4 extraction from IPv6 addresses

如何使用 IPv4 / IPv6 轉換器 — 逐步教學

Choose a conversion mode (IPv4→IPv6, IPv6→IPv4, Expand, Compress).

Enter the IP address in the appropriate format.

IPv4 / IPv6 轉換器 — 常見問題

什麼是 IPv4 對映的 IPv6 位址？

An IPv4-mapped IPv6 address (::ffff:x.x.x.x) is used to represent an IPv4 address in an IPv6 format. This is commonly used in dual-stack applications where an IPv6 socket communicates with an IPv4 host.

可以將任何 IPv6 位址轉回 IPv4 嗎？

Only IPv6 addresses in the ::ffff:x.x.x.x or ::x.x.x.x format contain embedded IPv4 addresses. Native IPv6 addresses (e.g., 2001:db8::1) cannot be converted to IPv4 as they are different address spaces.
