IP and IPv6 Protocols
IP works using a system of numeric addresses and sub-networks (subnets). IP also features the companion protocol ICMP. A new version of IP, IPv6, will someday replace the IP system currently in common usage.
IP - Internet Protocol
IP is probably the world's single most popular network protocol. Data travels over an IP-based network in the form of packets. Each IP packet includes both a header (that specifies source, destination, and other information about the data) and the message data itself.

What Is a Port Number?
In computer networking, a port number is part of the addressing information used to identify the senders and receivers of messages. Port numbers are most commonly used with TCP/IP connections. Home network routers and computer software work with ports and sometimes allow you to configure port settings.

MAC - Media Access Control
MAC is a mechanism to support access control and identification of computers on an Internet Protocol (IP) network. MAC assigns a unique number to each IP network adapter called the MAC address.

ICMP
ICMP is a simple network protocol useful in IP network management and administration. All implementations of IP require an accompanying implementation of ICMP.

What is IPv6?
IPv6 is the next generation protocol for Internet Protocol (IP) networking. IPv6 coexists with and will someday replace the current IPv4 standard.

Vista and IPv6
The Microsoft Vista operating system contains built-in support for IPv6. While it's true that some extra traffic to DNS servers will be needed to support IPv6 queries, will Vista really cause Internet traffic problems?
