Abstract: Examples of the present disclosure describe systems and methods for using a host DNS local cache to enable DNS resolution during network connectivity issues. In examples, a DNS request from a virtual environment executing on a host device is received by a DNS forwarder implemented within the host device. The DNS forwarder determines that a DNS resolver external to the host device is unreachable to provide a DNS response for a domain name in the DNS request. In response to determining the DNS resolver is unreachable, the DNS forwarder identifies a DNS response corresponding to the domain name within a DNS local cache implemented within the host device. The DNS forwarder provides the DNS response to the virtual environment to satisfy the DNS request.

Abstract: A stern light manually insertible into and removable from a powered socket such as for a boat, is shown and described. The stern light comprises a light transmissive elongated post with a plurality of point light sources. Each point light source is individually controllable as to on-off and as to color, either from local pushbuttons or from a portable wireless transmitter. The point light sources may be controlled by a programmable controller which responds to the local pushbuttons or to the portable wireless transmitter, and may illuminate according to various lighting sequences, such as constantly on and such as flashing.

Abstract: An internally illuminated transparent rail, such as a handrail, is disclosed. The rail is fabricated from polycarbonate or the like, and contains one or more series of lighting elements such as LEDs. The LEDs are connected to a programmable controller which stores preloaded programming control sequences and features, and which can also receive commands wirelessly from e.g. a hand held user interface such as a cellular telephone. The rail includes stanchions for mounting to an environmental object such as a transport vehicle or a static structure.
