ip ddns name

Establishes a dynamic DDNS host name for the Island.

Syntax

[no] ip ddns name <string>

Syntax Description

Keyword	Description
no	(Optional) Deletes an existing DDNS name.
string	The desired DDNS host name. This must be a simple host name, not a domain name. It may consist of between 1 and 63 alphanumeric characters or a minus sign ("-"). The first character must be a letter or number.

Defaults

No DDNS name is assigned by default.

Usage Guidelines

Island provides a DDNS service that assigns names with the "myisland.info" domain. The user may assign a simple host name using this command. For example, if "bobs-island" is specified, the resulting fully-qualified domain name (FQDN) will be "bobs-island.myisland.info".

There is no registration or authentication required for this service. Names are available on a first-come, first-served basis. Once a name is assigned to a specific Island, that name may not be assigned to another Island until a grace period has expired or the name is manually deleted using the "no" form of this command from the original Island with an active Internet connection.

The A and AAAA records for the FQDN will be updated automatically by the Island based on the public IPv4 and IPv6 addresses on the WAN port. If multiple WAN primary ports are in use (or multiple secondary WAN ports if no primary port is available), the A and AAAA records will be assigned arbitrarily to the IP address on one of the active ports.
