net,

mesh fabric, known from prehistoric times. Nets have been made of many materials, including sinews, strips of hide, silk, vegetable and synthetic fibers, and metallic threads. Their earliest use was probably for snaring animals and for fishing. Fishing nets include the stationary net, an early type; the drift net, an oblong vertical net, buoyed on its upper edge; the seine, whose ends are brought together to enclose the fish; and the bag-shaped trawl net, dragged along sea bottom. Hair nets include the gold or silver, wire or cord cauls worn in ancient Egypt, Greece, and Rome; reticulated caps and cauls popular in Europe especially in the 14th cent.; chenille or ribbon snoods of the 19th cent.; and the "invisible" net of human hair. Net fabrics include veilings, tulle, and maline, as well as heavier dress nets, curtain nets, and filet, a foundation for lace. Nettings are used also for safety nets, for hammocks, and for hoisting loads.

What does it mean when you dream about a net?

To cast a net as one does when attempting to catch fish or anything of value suggests that one is caught up in a net of intrigue or a complicated life situation.

(communications)
A number of communication stations equipped for communicating with each other, often on a definite time schedule and in a definite sequence.
(engineering)
Threads or cords tied together at regular intervals to form a mesh.
A series of surveying or leveling stations that have been interconnected in such a manner that closed loops or circuits have been formed, or that are arranged so as to provide a check on the consistency of the measured values. Also known as network.
(geology)
In structural petrology, coordinate network of meridians and parallels, projected from a sphere at intervals of 2°; used to plot points whose spherical coordinates are known and to study the distribution and orientation of planes and points. Also known as projection net; stereographic net.
A form of horizontal patterned ground whose mesh is intermediate between a circle and a polygon.
(mathematics)
A set whose members are indexed by elements from a directed set; this is a generalization of a sequence. Also known as Moore-Smith sequence.
A nondegenerate partial plane satisfying the parallel axiom.
(textiles)
Any fabric made in open hexagonal mesh.

(NETwork) Any term with a "net" prefix either means network or Internet. For example, a net address can mean a network address or an Internet address, depending on the context of the dialog. "Net" with a capital "N" generally refers to the Internet; for example, "the Net" is "the Internet." See also .NET Framework.
