Create an IP addressing plan that will grow. In traditional classful Each of the different departments needs to be separate and have their own IP address space. First, we need to plan our subnetting scheme and our subnetting strategy and steal as many bits from the host portion of the address as needed to represent the subnets that we have and the hosts that we have. That leaves us with the 7 bits for the host and that means 126 possible hosts per subnet. Other private networks like 192.168../16 and 172.16../12 are not big enough, no matter how small your company might be. the same size. Some examples are 200.x.x.x, 215.x.x.x, 221.x.x.x, 195.x.x.x. A private IP address or local IP is an address assigned to devices for use in a private network. The subnet and broadcast address must be found and reserved. Hence the IP range of this class should be 0-127 but 0.0.0.0 doesnt represent a valid network and 127.0.0.0 to 127.255.255.255 is reserved for local host loop back to verify TCP/IP services diagnostic functions. Let us see all these types of IP address in detail. addresses into eight subnets of 30 hosts each. Figure 1 First and Last Range Addresses. Thats because DNS names are cached by DNS servers, which means that they dont have to be resolved every time theyre used. That throws your whole scheme out, For your small network, maybe have one /24 for static assignments and one /24 for DHCP? Anyone may .

Consider the following real-world example: A small business plans to use the 192.168.1. network for its internal ( intranet ) hosts. In this case, the organization has the ability to extend the number of bits that are allocated for the subnetwork. Because an hexadecimal number uses 4 bits this means that an IPv6 address consists of 32 hexadecimal numbers. the four-part dotted decimal address has appended to it a slash and then a Broadcast addresses are used to send data packets to all devices on a network. For example, you can split a class C network containing 254 This could be due to a network that has outgrown its allotment of IP addresses. These octets are broken down to provide an addressing scheme that can accommodate large and small networks. As the subnet address is the lowest number in the range, it is 172.16.1.192; as the broadcast address is the highest address in the range, it is 172.16.1.255, leaving the addresses from 172.16.1.193 through 172.16.1.254 as usable.
