Program Plan Intro

IP addresses:

• The IP address denotes an unsigned integer that is 32-bit.
• The IP addresses is been stored by network programs in IP address structure.
• The addresses present in IP address structure are stored in network byte order.
•  An unsigned 32-bit integer is converted from host byte order to network byte order by “htonl” function.
• An unsigned 32-bit integer is converted from network byte order host byte order by “ntohl” function.
• The IP address is presented to humans in a form known as “dotted-decimal” notation.
  • Each byte is been represented by its corresponding decimal value and is separated by a period from other bytes.
