ClassDandEare not used for the host addressing. Class D addresses are used for multicast addresses. Class E addresses are reserved for research and development purposes. Multicast addresses are explained in the following tutorial. The subnet mask IP addresses use an additional component to distinguish...

Private IP addressing In classes A, B, and C, a range of IP addresses are set aside for private networks. These IP ranges aren't accessible via the internet. All public routers ignore any packets sent to them containing such an address. ...
The address 172.16.52.63 is a class B address. Its first octet is 172, which is between 128 and 191, inclusive. Class C networks use a default subnet mask of 255.255.255.0 and have 192-223 as their first octet. The address 192.168.123.132 is a class C address. Its first octet is...

A Class A, B, or C TCP/IP network can be further divided, or subnetted, by a system administrator. It becomes necessary as you reconcile the logical address scheme of the Internet (the abstract world of IP addresses and subnets) with the physical networks in use by the real world. ...
