You can also just spend $10 on a domain name with a registrar that offers dynamic DNS. Offhand, both Namecheap and Cloudflare do. I have no idea what my public IP address is because my router just updates it automatically for me. Plenty of DDNS desktop clients around if your router can’t for whatever reason.

I generally remap to swap caps lock with left control. Having control on the home row makes Ctrl shortcuts way less of a contortion act.

Useful in general but especially so on laptop keyboards.
