Dynamic DNS
Dynamic DNS (Domain Name Server) a dynamic IP address to be aliased to a static
hostname, allowing a computer on the network to be more easily accessible from
the Internet. Typically, when connecting to the Internet, the service provider assigns
an unused
IP address from a pool of IP addresses, and this address is used only for
the duration of a specific connection. Dynamically assigning addresses extends the
usable pool of available
IP addresses, while maintaining a constant domain name.
This allows to user to access a device (a camera, for example) from a remote loca-
tion, since the device will always have the same
IP address.
When using Dynamic DNS , each time the IP address provided by the ISP changes,
the DNS database changes accordingly to reflect the change. In this way, even
though the IP address of the computer changes often, its domain name remains
constant and accessible.
Opening a Dynamic DNS Account
To use Dynamic DNS , a free Dynamic DNS account must be opened at http://
www.dyndns.org/account/create.html.
When applying for an account, a user name and password must be specified. Have
them available when customizing the Router’s Dynamic
DNS feature. For more
