Each class uses the 32-bit IPv4 address space differently, providing more or fewer bits for the network part of the address. These classes are class A, class B, and class C.Class A Network NumbersA class A network number uses the first 8 bits of the IPv4 address as its “network part...
Classes of IP Addresses There are 3 main classes of IP addresses which can be organized in the table below: Classes of IP addresses Let’s go through this row by row. Class A Network Class Ahas an address range from0.0.0.0to127.255.255.255. The default subnet mask is255.0.0.0. That impl...
These classes are class A, class B, and class C. Class A Network Numbers A class A network number uses the first 8 bits of the IPv4 address as its “network part.” The remaining 24 bits contain the host part of the IPv4 address, as the following figure illustrates. Figure 10-3 ...
The 32-bit IP address is subdivided into two portions: the network address space and the host address space. The use of 32-bits does not change, but the use of the bits within the 32-bit address changes in order to define four classes of addresses. There are currently five defined addre...
Much in the same way that IP addresses are split into classes, so are ports. There are three ranges of ports: the well-known ports, the registered ports, and the dynamic/private ports.The Internet Assigned Numbers Authority (IANA) manages the allocation of port numbers, the regional ...

IPNetwork utility classes take care of complex network, IP, IPv4, IPv6, netmask, CIDR, subnet, subnetting, supernet, and supernetting calculation for .NET developers. It works with IPv4 as well as IPv6, is written in C#, has a light and clean API, and is fully unit-tested with 100%...
Understand different classes of IP address & “dotted quad”. Differentiate between Private and Public IP addresses. The TCP/IP model. Get a better understanding of commonly used TCP ( Transmission Control Protocol ) ports & services for example ports 21, 22, 53, 80, 110 and so much more....
The following table displays subnet masks for the Internet address classes.

IPv4 networks have five classes: A, B, and C, which we use all the time, D, the multicast class, and E, which is experimental and reserved for future use. With the advent of IPv6, it’s likely class E will never be used. A picture is worth a thousand words, and this table fro...
