subnets. The mask number represents the number of 1s in the binary of the address that is ’masked" against the address so that it ignores the last bits which are for the group of IP addresses in the masked address. The first address of a subnet block (all 0s) is called the network address or network ID. The last address (all 1s) is the broadcast address of the network. Typically the network address +1 or the broadcast address -1 is the gateway to the internet. The ’slash’ notation (ie /24) is known

belong to a subnet are addressed with a common‚ identical‚ most-significant bit-group in their IP address. This results in the logical division of an IP address into two fields‚ a network or routing prefix and the rest field or host identifier. The rest field is an identifier for a specific host or network interface. The routing prefix is expressed in CIDR notation. It is written as the first address of a network‚ followed by a slash character (/)‚ and ending with the bit-length of the prefix. For

What most people don’t realize is that with each one of those devices‚ you have to have an IP address to ensure that you can connect to the internet. Because more and more people around the world are using more internet enabled devices‚ the world is very quickly running out of IP addresses. History of IPv6 Up until very recently‚ every device used an Internet Protocol Version 4 (or IPv4) address. Since those addresses are becoming more scarce by the day‚ “the Internet Engineering Task Force
