Internet Protocol Adressing Scheme.

While assigning IP addresses to host on you network, you must assign an address based in the appropriate scheme. Based on your network design and access that is given to host or node. Deciding on an IP Addressing scheme for your Network will be dependent on the number of devices that you expect to be in the system because this will affects how you configure your network. For instance, your organization might require a small network of several dozen standalone systems that are located on one floor of a single building, this means that you might need to set up a network with more than a thousand systems in several buildings. This setup can require you to further decide how to divide your network into subdivisions that are called subnets.

When planning your network addressing scheme, consider the following factors:
The type of IP address that you want to use: IPv4 or IPv6.
The number of potential systems on your network.
The number of systems that are multihued or routers, which require an IP address for each interface.
Whether to use private addresses on your network or public addresses
Whether to have a DHCP server that manages pools of IPv4 addresses.
 Below is a rundown of IP addressing scheme and their descriptions?

IPv4 Addresses
These 32-bit addresses are the original IP addressing format that was designed for TCP/IP. Originally, IP networks have three classes, A, B, and C. The network number that is assigned to a network reflects this class designation plus 8 or more bits to represent a host. Class-based IPv4 addresses require you to configure a network mask, for the network number this, will then, make more IP's available for you to use in your network.

IPv6 Addresses: Internet Protocol version 6 is a set of IP address specifications, from the Internet Engineering Task Force (IETF) that's essentially a better version of IP version 4 (IPv4). The principles of IPv6 are similar to that of IPv4,  only that devices can use IPv6 as source and destination addresses to pass packets over a network, and tools like ping work for network testing as they do in IPv4, with some slight variations.

PRIVATE IP: These are IP addresses used by organizations for nodes requiring IP connectivity within the organizational network, but not acquiring external connections to the global internet>. IP addresses in each of the classes are A, B, and C is reserved as privateIPV4 address. Because they are not routable and private address does not because duplicate IP addresses conflict on the internet. Meanwhile these addresses are referred to as site local address in IPv6.
PUBLIC IP: Every public address is shared on the internet, so basically public IP are those IP shared on the internet, to make public IP’s unique and different from each other it is then shared by in blocks by an organization known as ICANN.

APIPA/LINK LOCAL: Automatic Private IP Addressing is a feature of windows that enables a DHCP domain name control protocol client computer to configure itself automatically with a random IPv4 address in range of to until a DHCP server is available to change that configuration.

 The block of addresses in the IPv4 block of 127.0.0/8 or IPv6::1ranges are reserved for loopback. Information sent out from the device is routed back to the source without any processing or change. This is designed to mainly use for testing and troubleshooting purposes only.
Static and dynamic addressing scheme

In IP addressing scheme you can sign IP statically by manually entering the IP address to each of the individual host or node on your network. The logic here requires that the administrator visit each node to manually address the scheme. On large network configuring static IP on each node of every network and host can be very tedious and time consuming at the same time, can prone to errors that largely affect communication on the network. For me static addressing should be dedicated main on network infrastructures like routers, switches, printer and servers interfaces. To assign IP adress to your computer click on your computer network icon<<<<< click on network and sharing center. On the left side of your computer click on change on adapter settings<<<<< click on local area network,

Click on properties, then click on IPv4. Update your changes by telling the sysetem to use the following information and save your settings.

DHCP: Router has a DHCP interface ability to be configured as to lease IP’s to nearby clients to connect to the network automatically, once the wireless adopter is functioning the connection remain automatic, if the configure to accept DHCP connections.
DHCP requires a DHCP server configured with at least one functioning DHCP system. The system will contain a range of IP adresses and subnet masks, and can be able to contain other parameters like default gateway, and DNS server adresses, so in this case when the system is enabled it will then automatically leases configurations to a DHCP clients for a set up period of time.

 A gateway is a device or software that is configured with the ability to convert information from in-between incompatible systems and computers devices.
Gateway has the ability to translate information between different operating systems, or even email format, or between totally in different network. The implementation of gateway can be done on the hardware devices, software’s or even in both platforms. It is also good to install gateways on router, to allow the router to act as a gateway when there is need for it, this will ofcouse eradicate the need for a separate hardware platform.

In other hand to wrap this up, you should also know that without a default gateway the computers will only communicate between their LAN, they won't be able to route to the internet, or outside their local area so default gateway is needed to route to other networks in the system, this protocol directs the packets to a special address known as default gateway. Although default gate is not part of your addressing scheme but you should know that it connects the internal network to the external.
