Classless IP Addressing (part 1) Now that we've discussed Classful IP Addressing, we diagram and explain Classless IP addressing and examine what the differences are between the two and why they exist. You'll learn how to sub divide a class B IP address into smaller "sub" address or subnet mask when more addresses within the same IP address are needed and how those "sub" address are determined.
