ELEC - Lecture 2

  1. 1. Elective 2 – Windows Server Management<br />By: Aaron Angeles<br />
  2. 2. IP Address<br />Subnet<br />Topics<br />
  3. 3. is an address used in order to uniquely identify a device on an IP network<br />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<br />32 binary bits are broken into four octets (1 octet = 8 bits)<br />IP Address<br />
  4. 4. Each octet is converted to decimal and separated by a period (dot)<br />The value in each octet ranges from 0 to 255 decimal, or 00000000 - 11111111 binary<br />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.<br />IP Address<br />
  5. 5. Video Components of an IP Address:<br />Video<br />IP Address<br />
  6. 6. Classes of IP Address:<br />IP Address<br />
  7. 7. IP Communication within a Single Networks:<br />1.) Determine local or remote networks<br />2.) Resolve destination IP to MAC Address<br />3.) Address packet<br />4.) Deliver packet to destination.<br />IP Address<br />
  8. 8. How IP address are wasted<br />Video<br />IP Address<br />
  9. 9. Private IP addresses:<br /> through<br /> through<br /> through<br />IP Address<br />
  10. 10. Subnets<br />
  11. 11. A physical segment of a network that is separated from the rest of the network by a router or routers. <br />defines the part of an IP address that is the network ID and the part of an IP address that is the host id.<br />composed of four octets, similar to an IP address<br />Subnet<br />
  12. 12. Considerations for creating a Subnet:<br />Determine the number of physical segments on your network.<br />Determine the number of required host addresses for each physical segment. <br />Based on the requirements as determined in steps 1 and 2 define the following<br />One subnet mask for your entire network<br />A unique subnet ID for each of the physical segment<br />A range of host IDs for each subnet.<br />Subnet<br />
  13. 13. Variable Length Subnet Masks (VLSM)<br />is a method of creating different-size subnet masks to conserve IP address<br />is a technique that allows network administrators to divide an IP address space to subnets of different sizes, unlike simple same-size Subnetting<br />is a means of breaking down IP addresses into subnets (multiple levels) and allocating it according to the individual need on a network<br />Can also be called classless IP Addressing<br />Subnet<br />
  14. 14. Formula for Computing the number of hosts available on a subnet:<br />Total Host = 2n -2<br />Where n = number of bits turned off (value of 0) on a subnet masks<br />Subnet<br />
  15. 15. For example:<br />Subnet<br />
  16. 16. QUESTIONS<br />
  17. 17. Determine the network ID of an IP Address:<br />Seatwork:<br />
  18. 18. Determine whether the two IP Address are on the same network:<br />Seatwork<br />
  19. 19. VLSM:<br />Main Network:<br />Original Subnet Mask:<br />Requirements:<br />No. of Subnet: 6<br />No of host required per subnet:<br />A - 25<br />B - 35<br />C - 80<br />D - 10<br />E - 2<br />F - 4<br />Seatwork:<br />
  20. 20. Answer:<br />
