A LAND (Local Area Network Denial) attack is a DoS (Denial of Service) attack that consists of sending a special poison spoofed packet to a computer, causing it to lock up. The security flaw was first discovered in 1997 by someone using the alias "m3lt", and has resurfaced many years later in operating systems such as Windows Server 2003 and Windows XP SP2.

Land, sometimes referred to as dry land, is the solid surface of the Earth that is not permanently covered by water. The vast majority of human activity occurs in land areas that support agriculture, habitat, and various natural resources.

The suffix -land which can be found in several countries' name and country subdivisions indicates a toponymy—a land. The word came via Germanic "."

Länder (singular Land) or Bundesländer (singular Bundesland) is the name for (federal) states in German-speaking countries.
