IPv4 Address parts

PreviousIPv4:NextIPv4 Address Classes

Last updated 4 years ago

Address is divided into 2 parts:

    1. Network Port

    2. Host Portion

1. Network Portion (NID):

  • Network Portion also called Network ID (NID) is used to identify a specific Network.

  • Upon receiving the packet, a Router looks at the DIP & matches the Network Address stored in its Routing Table.

  • The Real-life equivalent of NID is a Pin code of an area where only your area code is mentioned but not your read house address

Host Portion (HID):

  • Host Portion also called Host ID (HID) is used to identify a specific endpoint (devices) on a Network.

  • E.g. A PC, SmartPhone, Servers, Printers, etc.

  • The Real-life equivalent of HID is your House Room Number where your actual House Address is mentioned but not your Pin code.
