Public and Private Addresses

 
Public Addresses

آدرس های که توسط InterNIC به واحد های متقاضی در سرتاسر جهان داده می شود IP Address Public گفته می شود . این آدرسها در Internet بکار می رود . مانند آدرس Public شرکت Microsoft

 که  24/207.46.130.0  می باشد

InterNIC ( Internet Network  Information Center )

 
Private Addresses

 اما آدرس هایی که می توان در شبکه های Intranet و یا  Private Network از آنها استفاده کرد را Private Address گفته می شود که در زیر آنها را مشاهده می کنید .

 Class A 10.0.0.0/8
10.0.0.1 ..... .  .... 10.255.255.254
Class B 172.16.0.0/12
172.16.0.1 .. .    ...... 172.31.255.254
Class C 192.168.0.0/16
192.168.0.1 ... . ... . .... 192.168.255.254
The private address space specified in RFC 1918 is defined by the following three address blocks:
- -
  • 10.0.0.0/8

    The 10.0.0.0/8 private network is a class A network ID that allows the following range of valid IP addresses: 10.0.0.1 to 10.255.255.254. The 10.0.0.0/8 private network has 24 host bits that can be used for any subnetting scheme within the private organization.

     

  • 172.16.0.0/12

    The 172.16.0.0/12 private network can be interpreted either as a block of 16 class B network IDs or as a 20-bit assignable address space (20 host bits) that can be used for any subnetting scheme within the private organization. The 172.16.0.0/12 private network allows the following range of valid IP addresses: 172.16.0.1 to 172.31.255.254.

     

  • 192.168.0.0/16

    The 192.168.0.0/16 private network can be interpreted either as a block of 256 class C network IDs or as a 16-bit assignable address space (16 host bits) that can be used for any subnetting scheme within the private organization. The 192.168.0.0/16 private network allows the following range of valid IP addresses: 192.168.0.1 to 192.168.255.254.
