DDNS(Dynamic Domain Name System)

1. What is DDNS Service?
DDNS (Dynamic Domain Name System) is a service that maps domain names to IP addreesses. DDNS serves a
similar purpose to DNS. Unlike DNS that only works with static IP addresses, DDNS works with dynamic IP
addresses, such as those assigned by ISP or other DHCP server. And it provides client machines with a static
DNS name even if their IP address is dynamically assigned.
DDNS is popular with home networkers, who typically receive dynamic, frequently-changing IP addresses from
their service provider. To use DDNS, one simply signs up with a provider and installs network software on their
host to monitor its IP address.
