Again, the subnet and broadcast address must be found and reserved. 10.x.x.x; anarchy and crawling chaos (/22 is actually a damn useful subnet, not too big and not too small, so keep the same irrespective of the size, second octet defines a primary location, third defines a sub-location); gateway is always 1, servers start at 11 (with primary DNS being 11), then clients (starting at 10.x.1.x/10.x.5.x/etc using a /22 subnet), finally printers and other devices (starting at 10.x.3.x, 10.x.7.x, etc); servers with the same roles in each subnet have the same address where possible; DHCP for client PCs, static for everything else, reservations used for certain "special" clients where there are legacy apps and legacy security models that rely on a specific IP address. In this case, the organization has the ability to extend the number of bits that are allocated for the subnetwork. WebThe first IP subnet would be 192.168.0.1 through 192.168.0.255 and 192.168.1.0 through 192.168.1.254. Each rack get's a /24, which I terminate on a pair of core switch/routers.

An IP addressing plan is a document usually developed by network/design engineers to show how the IP addresses will be distributed among the network devices based on the network architecture or topology in a way that support the required services. The third subnetwork will begin where the second left off at 172.16.0.128 and go up to 172.16.0.191; this range is shown in Figure
