Services
1.1 Overview
The Services module incorporates two functions, Dynamic DNS (DDNS) and UPnP (Universal
Plug and Play) to provide convenient network services.
1.2 Support Features
Dynamic DNS
Nowadays, network protocols such as PPPoE and DHCP are widely employed by ISPs to
assign public IP addresses to users. The use of these protocols can cause the user’s public
IP address to change dynamically. DDNS is an internet service that ensures a fixed domain
name can be used to access a network with a varying public IP address. This means the
user’s network can be more easily accessed by internet hosts.
UPnP
With the development of networking and advanced computing techniques, greater
numbers of devices feature in networks. UPnP is designed to solve the problem of
communication between these network devices. UPnP function allows devices dynamically
discover and communicate with each other without additional configurations. For example,
it allows the download of P2P software without opening ports.
