Abstract
An exemplary failover module includes (a) instructions to respond to a connection problem to a host server at an IP address by selecting a different IP address from a cached list of IP addresses for a domain name associated with the host server and (b) instructions to return the selected, different IP address to future name queries where the instructions to respond, the instructions to initiate, and the instructions to return execute at an operating system level of a computing device configurable to connect to at least one of a plurality of host servers. Such a module may include instructions to optionally initiate a connection to a host server at the selected, different IP address. An exemplary failover module may optionally select an IP address based in part on Internet Location Coordinates (ILCs) where the host servers reside in an ILC enhanced Domain Name System (DNS). Other methods, devices and systems are also disclosed.
