3.7.2 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.
