DDNS use No-IP

Dependents:   TCPEchoClient-WIZwiki-W7500

Prerequisite

This is DDNS_NoIP Library. DDNS(Dynamic DNS) host name is linked up to the uesr's dynamic IP address. Whenever the IP changes a dynamic DNS client will send an update to No-IP with the current IP address and then No-IP propagates the DNS change to the internet within seconds.
