Download as PPTX, PDF1 like792 views
The document introduces IPv4 addressing, explaining its structure as a 32-bit binary number with over four billion possible combinations. It outlines the use of subnet masks to differentiate between network and node portions of IP addresses. Additionally, it emphasizes the logical nature of IP addressing, allowing for easier modifications compared to physical MAC addresses.

- 5. Page 5 When Bob on network A wants to view a Web page hosted on a server on network C, how does his computer know where to send Bob? Well somehow Bob has gotten the server’s IP address (either in IPv4 or IPv6 format). IP addresses are the location of the PC or server, identified as both network location and host location within that network. Introduction to IPv4 I.
- 6. Page 6 IP addressing provides a logical addressing scheme for our computers so that they can communicate on networks. Being logical means that an IP address can be changed with minimal fuss at any time, unlike a MAC (media access control) address, which is physically embedded into devices. Introduction to IPv4 I.

- 8. Page 8 As IPv4 is made up of a 32- bit binary number, there are 232 possible address combinations. That’s 4,294,967,296 possible combinations. With all of these possibilities, a process needed to be developed to keep everything neat and tidy and, most of all, findable. The implementation of the subnet mask was the answer.

Page 9 – Converting binary to decimal. » It’s very useful to understand how to convert binary (base 2) to decimal (base 10). • http://www.wikihow.com/Convert-from-Binary-to-Decimal. – Initial properties of IPv4. » 32-bit binary number. » Divided into four sets of eight (called octets) that are separated by periods (each octet is 8 bits, which is equal to one byte). » Represented in human friendly format by a dotted decimal format. » Requires the use of a mask to determine which portion defines the network and which portion defines the node. This is called the subnet mask. » The subnet mask has the same format as the IP address (32- bits and represented in dotted decimal format). Introduction to IPv4 I.

Topic Purpose of IP addressing. Summary IPv4 is made up of a 32-bit binary number (base 2). There are over four billion possible combinations. A subnet mask is used to allow for the identification of the network and node portions of the IP address. IPv4 address properties.
