Router User Manual
NOTE
: The configured time settings lose once the router is powered
off. But it obtains the GMT time automatically when you connect it to the
Internet. Features/functions based on time (e.g. security settings) take
effect only after time settings are configured manually or updated
automatically from Internet.
10.2 DDNS
Dynamic DNS or DDNS is a term used for the updating in real time of
Internet Domain Name System (DNS) name servers. We use a numeric
IP address allocated by Internet Service Provider (ISP) to connect to
Internet; the address may either be stable ("static"), or may change from
one session on the Internet to the next ("dynamic"). However, a numeric
address is inconvenient to remember; an address which changes
unpredictably makes connection impossible. The DDNS provider
allocates a static hostname to the user; whenever the user is allocated a
new IP address this is communicated to the DDNS provider by software
running on a computer or network device at that address; the provider
distributes the association between the hostname and the address to the
Internet's DNS servers so that they may resolve DNS queries. Thus,
uninterrupted access to devices and services whose numeric IP address
may change is maintained.
