Very interesting! I found this children’s book called The Story
About Ping. Curiously, if you read the book, you can trace many
parallels with the modern Unix ping command and the Duck named
“Ping” described n the story. Note, however, that the book was
written decades in advance of the Unix ping command. In older tech
circles, apparently this book has become quite popular. In the modern
tech community, apparently it isn’t nearly as popular.
