Class D and E:
Class D is a class with first 4 MSB (Most significance bit) set to 1-1-1-0 and is used for IP Multicast.
See also RFC 1112. Class E is a class with first 4 MSB set to 1-1-1-1 and is used for IP broadcast.
According to IANA (Internet Assigned Numbers Authority), there are three specific IP address blocks
reserved and able to be used for extending internal network. We call it Private IP address and list
below:
Class A 10.0.0.0 --- 10.255.255.255
Class B 172.16.0.0 --- 172.31.255.255
Class C 192.168.0.0 --- 192.168.255.255
Please refer to RFC 1597 and RFC 1466 for more information.
Subnet mask:
It means the sub-division of a class-based network or a CIDR block. The subnet is used to determine
how to split an IP address to the network prefix and the host address in bitwise basis. It is designed
to utilize IP address more efficiently and ease to manage IP network.
For a class B network, 128.1.2.3, it may have a subnet mask 255.255.0.0 in default, in which the first
two bytes is with all 1s. This means more than 60 thousands of nodes in flat IP address will be at the
same network. It’s too large to manage practically. Now if we divide it into smaller network by
extending network prefix from 16 bits to, say 24 bits, that’s using its third byte to subnet this class B
network. Now it has a subnet mask 255.255.255.0, in which each bit of the first three bytes is 1. It’s
now clear that the first two bytes is used to identify the class B network, the third byte is used to
identify the subnet within this class B network and, of course, the last byte is the host number.
Not all IP address is available in the sub-netted network. Two special addresses are reserved. They
are the addresses with all zero’s and all one’s host number. For example, an IP address 128.1.2.128,
what IP address reserved will be looked like? All 0s mean the network itself, and all 1s mean IP
broadcast.
