What is a network address?
A network address is an identifier for a node or host on a telecommunications network. Network addresses are designed to be unique identifiers across the network, although some networks allow for local, private addresses, or locally administered addresses that may not be unique.
What is the IPv4 and IPv6?
The Internet Protocol version 4 (IPv4) is a protocol for use on packet-switched Link Layer networks (e.g. Ethernet). IPv4 provides an addressing capability of approximately 4.3 billion addresses. The Internet Protocol version 6 (IPv6) is more advanced and has better features compared to IPv4.
What is a subnet?
A subnet mask is like an IP address, but for only internal usage within a network. Routers use subnet masks to route data packets to the right place. Subnet masks are not indicated within data packets traversing the Internet — those packets only indicate the destination IP address, which a router will match with a subnet.
What is network prefix?
A network prefix is an aggregation of IP addresses. Currently, the Internet runs two protocol versions of IP: version 4 and 6. ... The bitmask or prefix length defines the size of the aggregation. It effectively defines the amount of bits that determine the aggregation itself. For example, 192.50.
What is network range?
Each of the normal classes also have a range within them that is used to designate private network addresses. For instance, for class A addresses, the addresses from 10.0. 0.0 to 10.255. 255.255 are reserved for private network assignment. For class B, this range is 172.16.
