Static address never changes but dynamic addresses are temporary. For more information please visit our "whatsmyipaddress.net" tool.

The Internet protocol called IP is the part of TCP/IP (transfer control protocol and internet protocol). • IP is specified into two parts: The interface with a TCP, specifying the services regarding IP provides and another is actual protocol format.
IP Services: • The services to be provided across protocol layers (e.g. between IP and TCP) are expressed in terms of primitives and parameters. • A primitive specifies the function to be performed, and the parameters are used to pass data and control information.
The actual form of primitives is implementation dependent. An example is a subroutine call. • IP provides two service primitives at the interface to the next higher layer. • The Send primitive is used to request transmission of a data unit. The Deliver primitive is used by IP to identify a user of the arrival of a data unit.
The pare-meters associated with the two primitives are as follows: • Source address: Internetwork address of sending IP entity. • Destination address: Internetwork address of destination IP entity. • Protocol: Recipient protocol entity (an IP user, such as TCP)
Type of service Indicators: Used to specify the treatment of t he data unit in its transmission through component networks. • Identification: Used in combination with the source and destination addresses and user protocol to identify the data unit uniquely. This parameter is needed for reassembly and error reporting. • Data length: Length of data being transmitted. • Data: User data to be transmitted.
IP address is 32 bits long. One portion of the address indicates a network and the other portion indicates the host or router on the network. • This means that there is sense of hierarchy in IP addressing. • To reach a host on the network internet, we must first reach the network using the first portion of the address. • Then we must reach the host itself using the second portion.
In other words, Classes A, B and C in the IP addressing are designed with two levels of hierarchy. • IP address can be Static or Dynamic. Static address never changes but dynamic addresses are temporary. • If you want to know that, what is my IP address? then simply visits our our tool whatsmyipaddress.net.
