Communications system with dynamic or changing mapping correspondence between the respective set of domain names and the network addresses

A computer-implemented method comprising:

• accessing a database of information indicating rights associated with respective accounts according to respective settings files and associated with a data-communications service provider for providing data-communications services;
• mapping domain names of a respective set of domain names to network addresses according to a mapping function indicated in a respective one of the settings files and monitoring at least one operating status of the provided data-communications services associated with one or more servers designated to provide the data-communications services, using a set of criteria indicated in the respective one of the settings files, wherein the settings file for a first one of the respective accounts includes or indicates the mapping function and the set of criteria customized for the first one of the respective accounts;
• and
• using the mapping function, based on input data from an authorized user at a user interface, to adjust the settings file for the first one of the respective accounts and, in response, changing mapping correspondence between the respective set of domain names and the network addresses.

A data-storage device including instructions which, in response to being executed by computer circuitry, cause the computer circuitry to carry out a set of steps, the set of steps comprising:

• accessing a database of information indicating rights associated with respective accounts according to respective settings files and associated with a data-communications service provider for providing data-communications services;
• mapping domain names of a respective set of domain names to network addresses based on a mapping function indicated in a respective one of the settings files, and monitoring at least one operating status of the provided data-communications services associated with one or more servers designated to provide the data-communications services based on a set of criteria indicated in the respective one of the settings files, wherein the settings file for a first one of the respective accounts includes or indicates the mapping function and the set of criteria customized for the first one of the respective accounts;
• using the mapping function to change mapping correspondence between the respective set of domain names and the network addresses;
• and
• receiving data, responsive to input from an authorized user at a user interface, to adjust the settings file for the first one of the respective accounts.
