The subnet calculator allows a subnet ID to have its final octet equal to the final octet of its subnet mask - for example, a class C network address of 192.168..192 with a subnet mask of 255.255.255.192 is permitted. The above is generally accepted as being 'normal', however, certification students should keep in mind that, in some

So, 255.255.255.0 means that the first three numbers are being used to define the subnet. A subnet mask of 255.255.255.0 is actually 24 binary ones, followed by 8 binary zeros. The image above shows how you define the subnet for an Asus router. The subnet mask goes hand in hand with assigning the router an IP address (our next topic below).
A subnet is division of an IP network (internet protocol suite), where an IP network is a set of communications protocols used on the Internet and other similar networks. It is commonly known as TCP/IP (Transmission Control Protocol/Internet Protocol). IPv4 subnet mask is 32 bits large. In a valid subnet mask network part is represented with "1" from left side followed and ended by host part "0" - 11111111.11111111.11111111.00000000 (binary form), 255.255.255.0 (dotted-decimal form) or simply "/24" (where 24 represents that subnet network part is 24 bits long). IP block: Notation: Subnet mask: Inverse mask: 1 /32 (single) 255.255.255.255: 0.0.0.0 : 2 /31 : 255.255.255.254: 0.0.0.1 : 4 /30: 255.255.255.252: 0.0.0.3 : 8 /29 A Full IP subnet cheat sheet in a table format for your day to day subnetting tasks. IPv4 chart includes cidr, subnet mask, wildcard and IPv6 chart includes number of /48, /56, /64, /127 per prefix Addresses Hosts Netmask Amount of a Class C /30: 4: 2: 255.255.255.252: 1/64 /29: 8: 6: 255.255.255.248: 1/32 /28: 16: 14: 255.255.255.240: 1/16 /27: 32: 30: 255.255 Enter your netmask (s) in CIDR notation (/25) or dotted decimals (255.255.255.0). Inverse netmasks are recognized. If you omit the netmask ipcalc uses the default netmask for the class of your network. Look at the space between the bits of the addresses: The bits before it are the network part of the address, the bits after it are the host part.
