This document discusses IP addressing and subnetting. It defines IP addresses and subnets, explaining that IP addresses are made up of 32 binary bits that can be divided into a network portion and host portion using a subnet mask. It also discusses private IP addresses, calculating the number of available hosts on a subnet, and using variable length subnet masking to efficiently allocate addresses across multiple subnets with different size requirements.
3. is an address used in order to uniquely identify a device on an IP network 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 32 binary bits are broken into four octets (1 octet = 8 bits) IP Address
4. Each octet is converted to decimal and separated by a period (dot) The value in each octet ranges from 0 to 255 decimal, or 00000000 - 11111111 binary When assigning an address to a host, the first and last addresses are not to be assigned. The first address is the Network Address and last is reserved as the Broadcast Address. IP Address
7. IP Communication within a Single Networks: 1.) Determine local or remote networks 2.) Resolve destination IP to MAC Address 3.) Address packet 4.) Deliver packet to destination. IP Address
11. A physical segment of a network that is separated from the rest of the network by a router or routers. defines the part of an IP address that is the network ID and the part of an IP address that is the host id. composed of four octets, similar to an IP address Subnet
12. Considerations for creating a Subnet: Determine the number of physical segments on your network. Determine the number of required host addresses for each physical segment. Based on the requirements as determined in steps 1 and 2 define the following One subnet mask for your entire network A unique subnet ID for each of the physical segment A range of host IDs for each subnet. Subnet
13. Variable Length Subnet Masks (VLSM) is a method of creating different-size subnet masks to conserve IP address is a technique that allows network administrators to divide an IP address space to subnets of different sizes, unlike simple same-size Subnetting is a means of breaking down IP addresses into subnets (multiple levels) and allocating it according to the individual need on a network Can also be called classless IP Addressing Subnet
14. Formula for Computing the number of hosts available on a subnet: Total Host = 2n -2 Where n = number of bits turned off (value of 0) on a subnet masks Subnet
19. VLSM: Main Network: 192.168.10.0 Original Subnet Mask: 255.255.255.0 Requirements: No. of Subnet: 6 No of host required per subnet: A - 25 B - 35 C - 80 D - 10 E - 2 F - 4 Seatwork:
