Good luck with the link still being usable in a month or a year. There&#x27;s a reason we use domain names for sharing. Not only because they are friendly to read and remember, but also because IPs are typically far more transient than domain names.<p>The IPs behind my projects have changed dozens of times over the years (new server, changing hosting provider, adding a load balancer, etc.). A simple DNS change allows the same domain name to follow the project.<p>I&#x27;m actually surprised HN permits links to IP addresses. While links posted here are not guaranteed to point to the same content in the future anyway, it is more likely that an IP address will change before the project is taken down entirely. Search engine posterity and all.
