Imagine you have a subnet of 192.168.0.0 with a mask of 255.255.255.0 Now you know that you have 254 hosts available. Why? Because the HOST portion of the subnet in bold 192.168.0.0 equal the formula 2^8 - 2 = 254 So your valid hosts would be 192.168.0.1 to 192.168.0.254 The network address is: … 255.255.255.0 or /24. subnetting question? | Yahoo Answers Apr 23, 2011 Subnet Masks - CNES Number of Addresses Number of Bits Prefix Classful Notation Mask; 1: 0 /32: 255.255.255.255: 2: 1 /31: 255.255.255.254: 4: 2 /30: 255.255.255.252: 8: 3 /29: 255.255 Networking Concepts — Understanding CIDR Subnet Mask
Question about 255.255.254.0 Subnet Mask Solutions
15 subnet bits and 9 host bits. The block size in the third octet is 2 (256 - 254). So this makes the subnets in the interesting octet 0, 2, 4, 6, etc., all the way to 254. The host 10.16.3.65 is in the 2.0 subnet. The next subnet is 4.0, so the broadcast address for the 2.0 subnet is 3.255. The valid host addresses are 2.1 through 3.254. Apr 23, 2011 · /x just indicated the amount of networking bits, the remaining bits are the host portion of the subnet. For example a /24 would mean a subent of 255.255.255.0, a class C address and any ip address between 192.0.0.0 - 223.255.255.255 A subnetwork or subnet is a logical subdivision of an IP network.: 1,16 The practice of dividing a network into two or more networks is called subnetting. Computers that belong to a subnet are addressed with an identical most-significant bit-group in their IP addresses.

Examples 209.60.128.0 is a class C network address with a natural mask of /24. 209.60.128.0 /22 is a supernet which yields: 1.5. Understanding CIDR Subnet Mask Notation The CIDR number comes from the number of 1's in the subnet mask when converted to binary. The common subnet mask 255.255.255.0 is 11111111.11111111.11111111.00000000 in binary. This adds up to 24 1's, or /24 (pronounced 'slash twenty four').
