Converter ng IPv4 ↔ IPv6

I-convert sa pagitan ng IPv4 at IPv6 address sa parehong direksyon. I-parse at beripikahin ang mga address, i-expand at i-compress ang IPv6 sa canonical na RFC 5952 anyo nito, i-map ang IPv4 sa IPv4-mapped at IPv4-compatible na IPv6 (o alinmang custom na /96 prefix), at kunin ang nakapaloob na IPv4.

What it does

The IPv4 ↔ IPv6 Converter translates between IPv4 and IPv6 addresses in both directions, entirely in your browser. Paste any address and it auto-detects the family, then shows the canonical RFC 5952 form, the fully expanded form, IPv4-mapped (::ffff:a.b.c.d) and IPv4-compatible representations, and any IPv4 embedded inside an IPv6 address. Everything runs 100% client-side - your input never leaves the page.

How to use it

Type an IPv4 (192.168.1.1) or IPv6 (2001:db8::1) address into the box - the family is detected automatically.
For an IPv4, read its IPv4-mapped and IPv4-compatible IPv6 forms. Optionally enter a custom /96 prefix (e.g. 64:ff9b::) to embed it under a NAT64-style prefix.
For an IPv6, read its canonical compressed form, its fully expanded form, and any IPv4 embedded in a mapped/compatible address.
Copy any result, or Copy share link to send the exact input and prefix to a teammate.

Examples

IPv4 → IPv6 (mapped & compatible)

Input: 192.168.1.1
IPv4-mapped IPv6: ::ffff:192.168.1.1
IPv4-compatible IPv6: ::192.168.1.1
Under prefix 64:ff9b::: 64:ff9b::192.168.1.1

IPv6 → canonical & expanded

Input: 2001:db8::8a2e:370:7334
Canonical (RFC 5952): 2001:db8::8a2e:370:7334
Expanded: 2001:0db8:0000:0000:0000:8a2e:0370:7334

Extract an embedded IPv4

Input: ::ffff:10.0.0.1 → Expanded 0000:0000:0000:0000:0000:ffff:0a00:0001, Embedded IPv4 10.0.0.1.

Good to know

Shareable: your address and prefix are encoded in the URL (?a=…&p=…), so a link reproduces the exact view.
Private: all parsing and conversion happen locally - safe for real network addresses.
RFC 5952: IPv6 output uses lowercase hex, no leading zeros, and collapses the longest run of zero groups to ::. Only ::ffff: mapped addresses render with a dotted-decimal tail; the deprecated compatible range renders as pure hex.
