This continues until the left-most bit, or most significant bit, which holds a value of 2^7. The bit just to the left of that holds a value of 2^1. It contains all the supporting project files necessary to work through the video course from start to finish. Here is how binary octets convert to decimal: The right most bit, or least significant bit, of an octet holds a value of 20. Cisco CCNA Packet Tracer Ultimate Labs: ICND2 Exam Preparation Labs This is the code repository for Cisco CCNA Packet Tracer Ultimate Labs: ICND2 Exam Preparation Labs, published by Packt. The value in each octet ranges from 0 to 255 decimal, or 00000000 – 11111111 binary. For this reason, an IP address is said to be expressed in dotted decimal format (for example, 172.16.81.100). Each octet is converted to decimal and separated by a period (dot).

The 32 binary bits are broken into four octets (1 octet = 8 bits). The address is made up of 32 binary bits, which can be divisible into a network portion and host portion with the help of a subnet mask. In order to subnet a network, extend the natural mask with some of the bits from the host ID portion of the address in order to create a subnetwork ID.Īn IP address is an address used in order to uniquely identify a device on an IP network.

Any device, or gateway, that connects n networks/subnetworks has n distinct IP addresses, one for each network / subnetwork that it interconnects.

Each data link on this network would then have a unique network/subnetwork ID. If you break a major network (Class A, B, or C) into smaller subnetworks, it allows you to create a network of interconnecting subnetworks. If you do not subnet, you are only able to use one network from your Class A, B, or C network, which is unrealistic.Įach data link on a network must have a unique network ID, with every node on that link being a member of the same network. Subnetting allows you to create multiple logical networks that exist within a single Class A, B, or C network.
