Web27 Aug 2015 · Remember our formula for new subnet mask kapag # of networks is NSM = OSM + bits barrowed. So /24 + 5(bits taken) = 29. Remember, 192 is a Class C ip address na merong 255.255.255.0 or /24 na default subnet mask. Therefore, 192.168.253.0/29 is the subnetted network that can accomodate the question. /29 = 255.255.255.248. Why?

WebThe first step in the subnetting process is to divide the allocated address of 192.168.10.0/24 into four equal size address blocks. Since 4 = 22, 2 bits are required to identify each of the 4 subnets. Next, take subnet #0 (192.168.10.0/26) and identify each of its hosts. Allocated Address Sub-networks 62 usable hosts/ sub-network (subnet #0) WebBenefits of Subnetting.
