    took a month to finish chapter 1 and 2 (shame on me :( ), and get stuck on a sentence in CIDR part. it says " .... But keep in mind that the largest subnet mask available can only be a /30 because you've got to keep at least 2 bits for host bits". I really confused the words in red here. why is 2 bits not 4 (don't laugh at me masters :oops: ,).
