The are just a few terms used in computer networking. More to follow.
Classful
Addresses – In a Classful addressing system all the
IP addresses that are available are divided into the five classes A,B,C,D, and
E.
Classless
address – The classless address system broadcasts subnets
unlike classful addresses that do not.
VLSM
– Variable
Length Subnet Masks were developed to allow multiple levels of subnetworked IP
addresses within a single network.
CIDR
– Classless
Inter-Domain Routing (CIDR) is a method of allocating IP addresses and routing
Internet Protocol packets.
Prefix
Length – The prefix length is a shorthand way of expressing
the subnet mask for a particular network.
IP Address Subnet
Mask Prefix Length
192.168.1.67 255.255.255.240 192.168.1.67 /28 ß Prefix Length
138.96.58.0 255.255.0.0 138.96.0.0 /16 ß Prefix Length
10.1.1.2 255.0.0.0 10.0.0.0 /8 ß Prefix Length
Route
Summarization – Route summarization is a term used to
describe the representation by a single network of a group of contiguous
networks. The point of route summarization is to optimize the routing.
Supernetting
– Supernetting
is the practice of using a summary network to group multiple classful networks
into a single network address. Supernetting can make the addresses appear as a
single large network, or supernet.
