A binary number that uniquely identifies a host computer connected to the Internet. The IP packet header provides an originating address field so that a host can identify itself as the originator of a packet. The IP packet header also provides a destination address field so that an originating host can identity the target host for which a packet is intended.For example, comprises 4 fields separated by dots and expressed as xxx.xxx.xxx.xxx, with each field given a value in decimal between 0 and 255.

DNS is an Internet service that translates domain names into IP addresses. Every time you use a domain name, therefore, a DNS service must translate the name into the corresponding IP address.For example, the domain name www.BoomIp.com might translate to 72.52.141.102!

Short for Transmission Control Protocol/Internet Protocol. TCP enables two hosts to establish a connection and exchange streams of data. TCP guarantees delivery of data and also guarantees that packets will be delivered in the same order in which they were sent.
