I
ICMP
Internet Control Message Protocol. A method for IP hosts to communicate status and error messages.
instance
An object derived from a class that contains actual data. For example, in database terms, an instance is a row of data from a table.
Instance method
An instance method is not a static or class method. It is bound to a specific instance of the class and generally acts on that instance or uses it as input. When you call an instance method, you pass in a full instance path (or relpath). There is no difference in visibility (scope) between instance and class methods. All methods are either instance or class methods.
Internet Protocol
Within TCP/IP, this protocol governs the breakup of data messages into frames, the routing of frames from source computers to destination computers, and the reassembly of frames into the original data messages at the destination.
See also frame.
Internetwork Packet Exchange
The Novell implementation of the Xerox Internet Datagram Protocol Exchange. The IPX protocol handles sessions and broadcasts.
inventory
Information that SMS inventory client agents collect for each client in the site. The inventory can include hardware and software information and collected files, depending on the administrator-defined configuration.
See also collected files; file collection.

IP address
A 32-bit binary number that identifies the network node to other nodes on the network. An IP address is expressed in dotted quad format, which consists of the decimal values of its 4 bytes, separated with periods for example, 127.0.0.1). The first set of numbers (127 in the example) identifies the network the node is connected to; the remaining numbers identify the node itself.
