6.3 DDNS
Dynamic DNS or DDNS is a term used for the updating in real time of
Internet Domain Name System (DNS) name servers. 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 host
name 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 host name 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. (You
need to have an account with one of the Service Providers in the drop-
down menu first.)
