Definitely Agree. I will often pause the television to better hear or track down the source of a barely audible sound…and feel like I can’t resume normal activities until I identify it. It really annoys my wife who either doesn’t hear it or just isn’t as audibly observant…and then I’m annoyed at my wife for having no concern about the bizarre out of ordinary unidentified sound that she is content to ignore.
Are you just talking about dynamic DNS services for one or a few home servers?
There’s always DynDNS, but that’s a paid service. I actually discovered that dynamic IP address service was provided free by Google when using Google Domains as the registrar, so I moved a few of my private domains over to Google several years ago to save myself $55 a year.
Unfortunately, Google Domains is shutting down and all registrar services and existing customer domains are getting moved to squarespace and I’ve not yet been able to determine if squarespace is going to be offering the free dynamic DNS service or not.
