I liked the idea to have these IPs dynamically detected at runtime, though some research showed that my current provider only renews these every 180 days, nowadays. So, no need for such a hyper-dynamic solution. Instead I use a variable now, which brings some other benefits, like adding arbitrary IPs as well. This might become handy in cases of CI/CD.
