7.3 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.
