DDNS: Dynamic Domain Name Server
DDNS is a service that maps Internet domain names to IP addresses. DDNS serves a similar
purpose to DNS: DDNS allows anyone hosting a Web or FTP server to advertise a public

for ADSL environments, which means your IP address will constantly change each time you
connect to the Internet. As a result, users from WAN environments will have much difficulty
finding the correct IP address. The DDNS (Dynamic DNS service) is created for exactly this
kind of moment. By updating your WAN IP address each time you connect to the Internet, the
