Core Protocols
The primary protocols in the internet layer are the Internet protocol (IP). It is implemented in two versions, IPv4 and IPv6. The Internet Control Message Protocol (ICMP) is primarily used for error and diagnostic functions. Different implementations exist for IPv4 and IPv6. The Internet Group Management Protocol (IGMP) is used by IPv4 hosts and adjacent multicast routers to establish multicast group memberships.

Famous quotes containing the word core:
“True, there are architects so called in this country, and I have heard of one at least possessed with the idea of making architectural ornaments have a core of truth, a necessity, and hence a beauty, as if it were a revelation to him. All very well perhaps from his point of view, but only a little better than the common dilettantism.”
—Henry David Thoreau (1817–1862)
