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.)
