DDNS is a service that maps internet domain names to IP addresses and allow you to access your home computer from anywhere in the world.
DDNS serves a similar purpose to Internet's Domain Name System (DNS) in such that DDNS lets you to host a web or VPN server advertise a public name instead of numbers.
Further, unlike DNS that only works with static IP addresses, DDNS is designed to also support dynamic (changing) IP addresses, such as those assigned by a DHCP server. That makes DDNS a good fit for home networks, which normally receive dynamic public IP addresses from their internet provider. The result is that if your IP address changes, your domain name will adapt to the new IP address.
