IPv4からIPv6への変換器
インターネット上で無料でIPv4からIPv6への変換が可能。インストール不要。マッピング型、6to4型、および互換性のあるアドレスフォーマットをサポート。
について IPv4 to IPv6 Conversion
Convert IPv4 addresses to various IPv6 representations を含む IPv4-mapped, IPv4-compatible, 6to4, と IPv6-translated addresses. Essential for network migration と dual-stack configurations.
Conversion Types
IPv4-mapped (::ffff:a.b.c.d) represents IPv4 hosts in an IPv6 context. IPv4-compatible (::a.b.c.d) was used for automatic tunneling. 6to4 (2002:aabb:ccdd::) enables IPv6 over IPv4 networks.
How to 使用
Enter an IPv4 address と the tool will display all available IPv6 conversion formats. Each result can be copied to clipboard.
▶What is an IPv4-mapped IPv6 address？
It's an IPv6 address that represents an IPv4 node, formatted as ::ffff: followed by the IPv4 address. 使用d by dual-stack systems to hとle both protocols.
▶Why are there multiple IPv6 formats？
Different transition mechanisms use different address formats. IPv4-mapped is for dual-stack, 6to4 is for tunneling, と each serves a specific purpose in IPv4-to-IPv6 migration.
▶Can I convert IPv6 back to IPv4？
For IPv4-mapped と IPv4-compatible addresses, yes. The last 32 bits contain the original IPv4 address. Pure IPv6 addresses cannot be converted back to IPv4.
