What is IPv4 Address classes?

IPv4 addresses are divided into classes. Below is the class range of IP addresses and default subnet masks:-                              Class                        Range                          … Read More »

What is IP address Subnetting? Explained in Detail

Subnetting IP Address. Subnetting allows you to create multiple logical networks that exist within a single Class A, B, or C network. There are so many reasons why we subnet: a. It helps in the preservation of address space in other not to waste addresses. b. It used for security. c. It helps to control network traffic due… Read More »

What is IPv6 Address?

IPv6 Expression and Examples Unlike the 32-bit with four 8-bit fields of IPv4 address, separated by dots. IPv6 process a larger, 128-bit and the use of colons to separate it’s 16-bit hexadecimal entries. Below explains how to shorten the IPv6 address: Lets use the IPv6 address: 2041:0000:130F:0000:0000:07C0:853A:140B. The Leading zeros in a field are optional. That means: the field… Read More »

What is IPv6 Routing Protocols? Explained with Examples

What is iPv6 Routing Protocols? Most of the routing protocols we’ve learned in IPv4 had been modified to be used for longer IPv6 addresses and different header structures. IPv6 routing protocols are similar to their IPv4 counterparts, but since an IPv6 prefix is four times larger than an IPv4 prefix, routing updates have to carry more information.  IPv4… Read More »

What is IPv6 Static and Default Route ? How to Configuration

Static and default routes IP configurations on network routers is to enable communication to remote networks that are not directly connected. There are similarities when configuring IPv4 and IPv6 static and default routes on Cisco Integrated Services Routers (ISRs), the only difference is the IP addressing formats and IPv6 routing had to be enabled on the router with the… Read More »

What is Port Address Translation ? Explained with Examples

What is NAT Overload or Port Address Translation PAT. NAT overload sometimes called PAT (Port Address Translation) maps multiple unregistered or private IP addresses to a single registered or public IP address by using different ports. This is what most home broadband routers do. Your ISP assigns an IP address to your router, but you find out that… Read More »

What is IP Address Class B Subnetting ? Explained with Examples

Subnetting Class B Addresses. Subnetting Class B network is much more similar to subnetting Class C, the only difference is that when subnetting class B, you will be working on the third octect; while Class C, you will work on the fouth octect. Look at this:   To enable you subnet Class B, use the same subnet numbers for the third octect… Read More »

Subnetting allows you to create multiple logical networks that exist within a single Class A, B, or C network. There are so many reasons why we subnet: a. It helps in the preservation of address space in other not to waste addresses. b. It used for security. c. It helps to control network traffic due to collisions of… Read More »

What are type of IP Addresses?

Type of Addresses in IPv4.  Within the IPv4 address range , there are three types of addresses: Network Address – The address by which we refer to the network. Broadcast Address – A special address used to send data to all hosts in the network. Host Address – The addresses assigned to the end devices in the network. Network Address The network… Read More »

What are Types of IPv6 Addresses ? Explained with Examples

 As with the IPv4’s Unicast, Broadcast and Multicast addresses that defines the basics of communication and connectivity on the internet, IPv6 managed to remove the broadcast (because of the difficulties it causes on a network through looping) from the trio and introduced Anycast. Lets look at these IPv6 address types in detail below: Unicast Address: Packets addressed to a unicast… Read More »
