4.4.4 DDNS Settings
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.
