View Full Version : IP Addressing

07-08-2007, 12:48 PM
I am currently studying towards earning the CCNA Certification, and have run into a roadblock. My question concerns a Class A IP Address. I am clear on the first 8 bits, or octet being used for the Network address, and the remaining 24 bits or three octets being used for the Host address. How is it that *6,777,2*4 hosts can be addressed? I hope I worded the question correctly, and that someone may be of some help. Thanks!
