Re: What's a good free DDNS solution?
Whilst router-based DDNS is a simple no fuss solution, for reasons now forgotten (I was probably experimenting - exploring solutions that would work with laptops) I used a scheduled job to run a Curl script to send me an email when my parents IP address changes, also I configured a BGinfo icon which parents can click on to run the Curl script and display their current public address. Aside: if they can't login then it is unlikely that I will be able to fix their problem remotely.
