Update AWS EC2 inbound security group rules when your IP address changes

I just released AWS IP Update, a Windows Tray application that updates inbound security group rules on AWS EC2 when your IP address changes.

This has been vaguely on my to-do list for years. I didn't bother because I knew how tedious it would be from that time I pulled Azure metrics into Google Data Studio (now Looker) via Apps Script. This whole thing was banged out by Claude Code in five volleys, and I think I wasted those because it could probably have single-shotted it. I did not write a character of code, and it was faster to create than the way I used to get access.

I have a monthly sys admin day where I patch all the things, pull a Google photos archive and run an old fashioned backup to an external hard drive. The hardest part of this psychologically has been getting access to AWS to patch by blog server and pull a backup. My IP address has changed, and I need to log into AWS, find the right settings, look up my external IP address (Google Search used to just show this but it's been broken for ages) and update the EC2 security group. Every other part of the routine is easy, the access part always bums me out. So this is a quick AI tool that not only saves a few minutes a month, it also helps with mood and blood pressure.
