I agree with you. @LeoNeeson. I registered a domain name with Dynu and used their dynamic DNS service for free. The reason I chose Dynu is because they offer more features than just IP update, including wildcard alias, IPV6 support,web redirect(port 80 redirect, URL forwarding),MX record,round robin DNS (multiple IP addresses for 1 hostname),offline settings(redirect to offline message or offline URL) and custom DNS records. Some online resources are supposed to be free only !
