What Is My IPv6 Address?

Use a request to an IPv6-only address service to see the IPv6 address that service observes for your connection. Select Check connection below. If the request fails, the address is unavailable for this test; that alone cannot identify whether the cause is your ISP, routing, a browser extension or the service.

Best solution

Use a request to an IPv6-only address service to see the IPv6 address that service observes for your connection.

Queries ipify’s IPv6-only endpoint. It never relabels an IPv4 address as IPv6.

Public IPv6 address

Start a lookup to see the address visible to ipify.

A VPN, proxy or relay can change the observed address. HTTPS request time is not ICMP ping, packet loss or internet speed.

Clicking Check contacts ipify, which sees the request address. Results stay in this page. No automatic polling.

How to Use This Check

Use the browser and connection you want to examine. If you recently changed Wi-Fi or VPN settings, run a fresh check rather than keeping the earlier result. The what is my IPv6 question is about the address used by this request, not a list of every IPv6 address configured on the computer.

Select Check connection and wait for the IPv6-only endpoint. A successful response is validated as an IPv6 address before display. A failed request keeps the address unavailable. The component does not switch to an IPv4 endpoint silently, because that would answer a different question while appearing to succeed.

Record the address and observation time only if you need them. IPv6 addresses can use compressed notation, and devices can have multiple addresses with different scopes or lifetimes. Do not assume that a local link-scoped address shown in system settings is the same address the internet-facing service observes.

If you need to compare address families, use the separate IPv6 test page. It queries IPv4 and IPv6 independently and keeps their outcomes separate. A result for one family does not fill in the other, and a failed family is not automatically evidence that every application using it will fail.

What the Result Actually Means

IPv6 uses a larger address space than IPv4 and commonly displays addresses as hexadecimal groups separated by colons. Compressed notation can omit runs of zero groups, so a shorter-looking address is not necessarily incomplete. The what is my IPv6 tool asks an IPv6-only service which source address reached it. That is an external observation. It cannot enumerate local adapters, reveal every temporary privacy address or determine all routing policies on the device. These limits matter when comparing the result with an operating-system network panel.

Reference meanings, not fabricated live measurements.
Field or observation Meaning
Successful IPv6 request Address observed by the IPv6 service
Failed request Address unavailable for this observation
Local link-scoped address Different scope; not a public-IP result
IPv4 response elsewhere Does not establish the IPv6 outcome

Limits and Common Misreadings

Do not turn a failed IPv6 endpoint request into a definitive “IPv6 unsupported” statement. Filtering, DNS resolution, routing and provider availability can affect the test. Keep the precise observation and investigate the relevant connection separately.

A VPN or proxy can alter how a request reaches the service. The address returned belongs to the connection the service observed, which may differ from the address a different application uses under split routing.

Avoid using a public IPv6 address as a permanent personal identifier. Address assignment and privacy behavior vary. Keep troubleshooting records only as long as needed and avoid sharing unrelated connection details publicly.

An Example of Careful Interpretation: Separate the Observation from Its Cause

A local settings panel can list an IPv6 address used only on the local link while the external tool reports a different address. Those are not interchangeable scopes. The external observation describes the source that reached the service, not every address assigned to the adapter. If the external request fails, do not paste a local link-scoped value into the public result field to make it appear complete. Save the failed observation as such, then inspect the relevant network configuration through tools on the device you control.

Keep a Useful Troubleshooting Record

Keep the question, input, observation time and source together. A bare address, percentage or status code is difficult to interpret later because it omits the connection and measurement context. When comparing two observations, note what changed between them: the target, network, VPN state, selected adapter, record type or remote origin. Change one relevant condition at a time when possible. That makes the comparison easier to explain without inventing a cause from one number.

Save only information you actually need. Network records can reveal infrastructure names and connection details, even when they do not contain a password. Remove unrelated identifiers before sharing a screenshot with another person. Never put private credentials in a domain field or publish an internal hostname as part of a public test. A copied result is a snapshot, not a promise that the same conditions still apply when someone reads it later.

Kepo is a Mac desktop-widget product for repeated checks and small workflows. A labeled troubleshooting note or a supported monitoring widget can keep the relevant context accessible while you work. The download link opens the product workflow; this article does not automatically install a configured diagnostic widget, transfer your network inputs or start a scheduled check. Confirm the actual widget’s capabilities before relying on it for ongoing observations.

Frequently Asked Questions

Does what is my ipv6 address? describe my entire network?

No. The steps and component above define the scope of this observation. A local adapter value, an external address and a remote probe result describe different viewpoints. Preserve that context and do not generalize a single observation to every application or connection.

What should I do when a result is unavailable?

Keep it marked unavailable. An unfinished or failed observation is not a successful zero result and does not establish the cause of a problem. Check the input and try again later only when another observation is useful. Respect provider limits rather than repeatedly retrying.

Does this page save a monitoring history or install a desktop widget?

No. The page provides the specific manual workflow described above. It does not schedule future tests or create a configured desktop widget. Save the relevant result yourself and use an explicitly supported monitoring feature if you need recurring checks.

Sources and Method

Primary references for the protocol, provider or operating-system steps.

A useful network answer states what was checked, where the observation came from and what remains unknown. Keep those distinctions when you save or share the result.

What Is My IP Address?

Your public IP address is the address an internet service sees for the connection reaching it. Select Check connection to query the IPv4 endpoint below. A VPN, proxy or shared network can change the address that service sees. This is different from the private address shown in your computer’s network settings.

IPv6 Test: Check Both Address Families

Run separate requests to IPv4-only and IPv6-only endpoints and compare the observed outcomes. This IPv6 test can show whether this browser reaches those two services now. It is not a full protocol certification, DNSSEC assessment, router audit or guarantee of connectivity to every IPv6 destination.
