I used noip.com for like 30 or 60 days. Then I got really annoyed at having to renew the DDNS every 30 days.
After switching to duckdns.org I haven't had any problems whatsoever. It's completely free and you don't have to renew anything manually. You obliviously still need to have a script running to update the DDNS though, otherwise it wouldn't be very dynamic would it.
