I’ve been working out a tolerable dynamic DNS solution for myself lately. After much effort, I’ve settled on running my own bind server (I last did this like 12 years ago, hah). I’ve written simple scripts that handle it for me and they work fine. However, I found for many of my domains hosted by GoDaddy, I couldn’t get it to use my new nameservers. Godaddy would let me switch my nameservers, but then they’d revert to their previous settings and I’d get an email containing the helpful message:
Error: Authorization error; 6007
