The address: 10.10.10.0 subnet mask 255.255.255.0 means that the subnet is a range of IP addresses from 10.10.10.0 - 10.10.10.255. The prefix-length in IPv6 is the equivalent of the subnet mask in IPv4. However, rather than being expressed in four octets like it is in IPv4, it is expressed as an integer between 1 through 128.
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.This results in the logical division of an IP address into two fields, the network number or routing prefix and the rest field You learn how to assign each interface on the router an IP address with a unique subnet. There are examples included in order to help tie everything together. Prerequisites 1 1 1 1 1 1 1 1 128 64 32 16 8 4 2 1 (128+64+32+16+8+4+2+1=255) Here is a sample octet conversion when not all of the bits are set to 1. In the following diagram, there is a subnet mask for a Class C address. The subnet mask is 255.255.255.128 which, when translated into bits, indicates which bits of the host part of the address will be used to determine the subnet number. Of course, more bits borrowed means fewer individually addressable hosts that can be on the network. The CIDR number comes from the number of ones in the subnet mask when converted to binary. The common subnet mask 255.255.255. is 11111111.11111111.11111111.00000000 in binary. This adds up to 24 ones, or /24 (pronounced 'slash twenty four'). A subnet mask of 255.255.255.192 is 11111111.11111111.11111111.11000000 in binary, or 26 ones A subnet mask neither works as an IP address nor does it exist independently of IP addresses. Instead, subnet masks accompany an IP address, and the two values work together. Applying the subnet mask to an IP address splits the address into two parts, an extended network address and a host address.
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. is 11111111.11111111.11111111.00000000 in binary. This adds up to 24 1's, or /24 (pronounced 'slash twenty four').
The subnet mask is 255.255.255.128 which, when translated into bits, indicates which bits of the host part of the address will be used to determine the subnet number. Of course, more bits borrowed means fewer individually addressable hosts that can be on the network.
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).
