Transcript

  • 1. Types Of Addresses
  • 2.
    • IP Addresses 2. MAC Addresses
  • 3. IP (Internet Protocol)
  • 4. What Is IP (Internet Protocol) ?
    • Any protocol that is the part of the TCP/IP protocol stack.
    • It is also the network protocol.
    • IP provides features for addressing.
  • 5. IP Addresses
  • 6. IP Addresses assigned to hosts using the TCP/IP suite of protocols
  • 7. IP addresses are of 32-bits IP addresses have two portions A . Network Portion B . Host Portion
  • 8. Example 042 - 7706570 042 = is network portion and it remains same throughout the network. 7706570 = is host portion and it varies from host to host.
  • 9. Range Of Decimal Values An IP address is expressed as Four decimal values in the range of 0 to 255 Dotted Decimal Notations These decimal values each represents Eight bits of the 32-bits address, known as an OCTET . This is called Dotted Decimal Notation. Example 155.127.231.124
  • 10. Classification Of IP Addresses
  • 11.
    • Note :
    • Value 127 is not in any class it is reserved for Loop Back Testing
    • It is used for checking of TCP/IP Stack on PC
    Research and Testing 240-255 Class E Multi Casting 224-239 Class D 8-bits 24-bits Data Communication 192-223 Class C 16-bits 16-bits Data Communication 128-191 Class B 24-bits 8-bits Data Communication 1-126 Class A Host Portion Network Portion Uses Range Class
