This URL is only for IPv4↔IPv6 Convert (network · ipv4 ipv6). Map between IPv4 and IPv4-mapped IPv6. Other Network tools on Tool-You look similar in the chrome, so the job definition below is the part that belongs to IPv4↔IPv6 Convert alone: IPv4 → ::ffff:a.b.c.d; mapped IPv6 → IPv4. Plain IPv6 is compressed. Accepts ::ffff:127.0.0.1.

How to use IPv4↔IPv6 Convert

Keep this tab on IPv4↔IPv6 Convert (/network/ipv4-ipv6). Pasting into the wrong Network tool (for example IPv6 Compress) changes the job.
Paste or type the input IPv4↔IPv6 Convert expects. Path hint: network · ipv4 ipv6. Map between IPv4 and IPv4-mapped IPv6.
Apply the IPv4↔IPv6 Convert action only. Is IPv4 is a different transform (Validate a dotted IPv4 address.). IPv4 → ::ffff:a.b.c.d; mapped IPv6 → IPv4. Plain IPv6 is compressed. Accepts ::ffff:127.0.0.1.
Copy the output of IPv4↔IPv6 Convert if you need it elsewhere. Size/complexity still follows: Valid IPv4 or IPv6. Mapped addresses decode to IPv4.
If the text job is actually Compress an expanded IPv6 address., leave IPv4↔IPv6 Convert and open IPv6 Compress.

When not to use IPv4↔IPv6 Convert

Skip IPv4↔IPv6 Convert when a neighbor tool matches better — start with IPv6 Compress or Is IPv4 — or when the description already warns the job will fail. In the tool’s own words: IPv4 → ::ffff:a.b.c.d; mapped IPv6 → IPv4. Plain IPv6 is compressed. Accepts ::ffff:127.0.0.1.
