Internet Protocol telephony or IP telephony has been in use for quite a while now. Once you send or obtain data (for example, an e-mail note or a Internet page), the message gets divided into little chunks known as packets. IP is the protocol that controls all site visitors on the Web – from that final-minute birthday email to that multimedia package deal from All of this data is transferred in line with the rules laid down by IP.

Early network design, when world end-to-end connectivity was envisioned for communications with all Web hosts, meant that IP addresses be uniquely assigned to a particular laptop or machine.

In IP packet headers, PHBs should not indicated as such; instead Differentiated Companies Codepoint (DSCP) values are used. RFC 1953 Ipsilon Move Administration Protocol Specification for IPv4 Model 1.0. This is essential as Web Management Message Protocol (ICMP) messages travels as the information part of an IP datagram.

IPv4 addresses are canonically represented in dot-decimal notation , which consists of four decimal numbers, every ranging from 0 to 255, separated by dots, e.g., Every half represents a group of 8 bits ( octet ) of the handle. Each class permits for a variety of legitimate IP addresses, shown within the following table.
