 The namespace for this extension is `https://podcastindex.org/namespace/1.0`. Clients which recognize this namespace must also recognize `https://github.com/Podcastindex-org/podcast-namespace/blob/main/docs/1.0.md` as identical. The suggested tag prefix for use in XML is `podcast`, but clients should support alternate prefixes for this namespace. If your application generates RSS feeds and you implement one or more elements below, you will need to link this DTD in your XML:
 
 ```
-<rss version="2.0" xmlns:podcast="http://podcastindex.net/namespace/1.0">
+<rss version="2.0" xmlns:podcast="https://podcastindex.org/namespace/1.0">
