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.)
