![]() ![]() This eliminates the possibility of IP conflicts in a network where two devices share the same IP address. Most systems, by default, are configured to obtain an IP automatically using the DHCP protocol. Once the lease time lapses, the client acquires a new IP address. Thus, it simplifies and makes the configuration of IP addresses more efficient. The DHCP server, which in most cases is a router, contains a pool of addresses that it leases out to client devices on a network for a certain period of time. DHCP IP AddressĭHCP ( Dynamic Host Configuration Protocol) is a client-server protocol that dynamically allocates IP addresses to client systems on a network. IP allocation on client machines or any end-point devices connected to a network is done either using the DHCP protocol or manual configuration where IP addresses are statically allocated. Dynamic (DHCP) and Static IP Configuration The fact is, it will take a while before IPv6 replaces or phases out IPv4. In fact, you’ll hardly ever need to configure an IPv6 on your device to provide connectivity. These extra bits provide more addressing space which will supplement the address provided by IPV4.Īlthough IPv6 is set to take over from IPv4 addressing in the near future, many organizations and ISPs still use and largely rely on IPv4 addresses. As you know by now, IPv6 contains 128 bits which is four times more than the number of bits in IPv4 (32 bits). IPv6 was developed as a solution to the imminent exhaustion of addresses in IPv4. This can be further shortened as follows. The remaining 64 bits identified the address on the nodes.īelow is an example of a full IPv6 address. The network part makes up the first 64 bits and is used for routing purposes. Like an IPv4 address, it is split into two parts: the network and host component. 192.168.50.15Īn IPv6 address is an alphanumeric address that is 128 bits long, arranged in eight groups, each of which contains 16 bits. All hosts in the same network share the same network portion.įor example, the following host IP addresses belong to the same network. This part uniquely identifies a host in a network. The remaining section of the IP address is the host portion, which is the section that determines the number of hosts in a network. The remaining 21 bits of the first three octets define the network ID, and the last octet defines the number of hosts.Īs such, Class C IP address produces the highest number of networks amounting to 2,097,150, and the least number of hosts per network which is 254 hosts. In a Class C network, the first two network bits are set to 1 while the third is set to 0, i.e. This class of IP is mostly used for small networks such as a home network or a small office or business. This class of IP is typically used for medium-large networks and yields 65,534 hosts per network with a total of 16,382 networks. The default subnet mask is 255.255.0.0 where the first 16 bits define the network ID. In Class B, the first two octets, or 16 bits are used to define the network ID. It yields a maximum of 16,777,214 hosts and 126 networks. This class is used in networks that command a large number of hosts. The remaining 24 bits are designated for hosts. The default subnet mask of class A is 255.0.0.0 with the first 8 bits used to identify the network. ![]() The Private IP addresses range from 10.0.0.0 to 10.255.255.255.Īddresses 127.0.0.0 to 127.255.255.255 are reserved for loopback and other diagnostic purposes, and hence are not allocated to hosts in a network.The Public IP addresses range from 1.0.0.0 to 127.0.0.0.In Class A type of network, the first 8 bits (octet) define the network, while the remaining 24 bits are reserved for the hosts in the network. There are 3 distinct classes of IP addresses used in computer networks: Class A, Class B, and Class C. The network section of an IP address identifies the class the IP address belongs. The first part represents the network section, while the remaining part defines the host section. An IPv4 address can further be divided into two sections. This is usually referred to as dotted-decimal format.Įach octet is made up of 8 bits which collectively represent a byte. An IPv4 (IP version 4) address is a 32-bit number that is split into four octets, with each octet separated by a period or a decimal point. ![]()
