On the topic of dns, I still use GoDaddy. People ask why, it's because GoDaddy seems like a good idea in 2003 when I got my first domain, and 2006 when I got my current one. At that point it's just inertia, I tend to buy several years in advance because I don't like annual payments, I know it makes me a weirdo. That means I'm locked in for several years and it's not enough of a problem to do anything about. Anyone who uses GoDaddy knows that they turned off their dynamic DNS option quite some time ago. My system is pretty stable so I don't usually need to change it, but if I have a power failure at home or I need to reboot my router, I obviously need to change my DNS at those moments. When I'm away from home, I end up having to use TeamViewer to hop into a jump box vm I have set up for that purpose. The two obvious problems with that are first of that TeamViewer is a proprietary product, and the second of all that they see me hopping into a jump box regularly and they assume that I'm a commercial customer. There is apparently a way to tell them that you're just a hobbyist, but I haven't gotten around to filing that. What I did do is set up a script that compares the current IP to my DNS IP, and if they are different then I send myself an email that contains the old IP in the new IP. This way, I don't need to hop into my network to find out what the new IP address is. I also added a little bit there to save the last successful IP address sent by email to /tmp/ so that if I lose my IP address but I'm doing something where I can't hop onto the GoDaddy website to fix it, I don't get 100,000 emails with my new IP address. I killed my house power a couple weeks ago, and the whole system worked exactly as intended. I was pretty happy to see that.
