Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.</p><span>Copyright © <!-- -->2024<!-- --> Apache Software Foundation, Licensed under the<!-- --> <a href="https://www.apache.org/licenses/LICENSE-2.0" target="_blank" style="text-decoration:underline">Apache License, Version 2.0</a>.<br/>Apache®, the names of Apache projects, and the feather logo are either<!-- --> <a href="https://www.apache.org/foundation/marks/list/" target="_blank" style="text-decoration:underline">registered trademarks or trademarks</a> <!-- -->of the Apache Software Foundation in the United States and/or other countries. .</span></div></div></footer></div></div><script id="__NEXT_DATA__" type="application/json">{"props":{"pageProps":{}},"page":"/documentation/developer-manual/ip-to-location","query":{},"buildId":"nMv34a5M-gkxRhkmXCCE_","nextExport":true,"autoExport":true,"isFallback":false,"scriptLoader":[]}</script></body></html> |
