In telecommunications, unicast is the addressing of a message to a single recipient.
The term unicast is formed in analogy to the terms broadcast , multicast and anycast . It is addressing schemes of the network layer in the OSI model .
The term unicast does not allow any conclusions to be drawn as to whether it is a bidirectional connection, i.e. whether the sender and receiver are communicating with one another, or whether the respective data is only transmitted in one direction ( unidirectional ).
With IPv6 , certain areas are reserved for unicast addresses, which are specified by ICANN .
Unicast addresses are used here, among other things, for the temporary connection to IPv4 networks ( global unicast transition address ) or for the assignment of individual devices within closed networks ( link-local unicast address ).
