CloudFlare and No-IP is that you need to own a domain name to make use of CloudFlare. No-IP However offers free subdomains, meaning it’s a costless service to use.
Cloudflare also offers more protection such as free SSL, anonymized IP, DDOS protection

server=api.cloudflare.com/client/v4
login=your_email
password=your_api-key
zone=your_domain.com
anything.your_domain.com
