Cyclades User's Guide manual Cidr Notation, Cluster, DNS Server, Domain Name

CIDR Notation	Classless Inter Domain Routing (CIDR) is a method for assigning
	IP addresses without using the standard IP address classes like
	Class A, Class B or Class C. In CIDR notation, an IP address is
	represented as A.B.C.D /n, where "/n" is called the IP prefix or
	network prefix. The IP prefix identifies the number of significant
	bits used to identify a network. For example, 192.9.205.22 /18
	means, the first 18 bits are used to represent the network and the
	remaining 14 bits are used to identify hosts. Common prefixes are
	8, 16, 24, and 32.
Cluster	A cluster is a group of one or more computers working as a group
	to execute a certain task. From the user standpoint, a cluster acts
	as a large computer system.
Community	The community name acts as a password and is used to
	authenticate messages sent between an SNMP client and a router
	containing an SNMP server. The community name is sent in
	every packet between the client and the server.
DHCP	Dynamic Host Configuration Protocol. A protocol for automatic
	TCP/IP configuration that provides static and dynamic address
	allocation and management.
	DHCP enables individual computers on an IP network to extract
	their configurations from a server (the 'DHCP server') or servers,
	in particular, servers that have no exact information about the
	individual computers until they request the information. The
	overall purpose of this is to reduce the work necessary to
	administer a large IP network. The most significant piece of
	information distributed in this manner is the IP address.
DNS Server	Domain Name Server. The computer you use to access the DNS
	to allow you to contact other computers on the Internet. The
	server keeps a database of host computers and their IP addresses.
Domain Name	The unique name that identifies an Internet site. Domain Names
	always have 2 or more parts, separated by dots. The part on the
	left is the most specific, and the part on the right is the most
	general. A given machine may have more than one Domain Name
