Andreas, Exequiel over here, the article's author. I did actually test the '.local' domain on macOS but didn't have any issue. However, after your comment I researched on the topic and found what you meant, then changed the example to use '.test' instead. Thank you for pointing that out!

Henrik, Exequiel here. Thank you for your suggestion, it didn't come to me naturally to implement it that way. I will implement that and add it to the article.
