IPv4 Addressing Basics IP address: 32 bits (4 octets) binary representation ‘dotted decimal’ is decimal translation of bit values by octet 11000001. 00000101. 00100010. 00001011 193 . 5 . 34 . 11 The binary values of each bit within the octet are predefined per Base2 numerical system 1 1 1 1 1 1 1 1 2 7 2 6 2 5 2 4 2 3 2 2 2 1 2 0 128 64 32 16 8 4 2 1 Any device on a network that needs to send and/or receive data requires an IP address Network Layer Address => comes in two parts: 1) Network Number: part of IP address that specifies the network to which the host (device) belongs **This is what the router needs to know 2) Host Number: part of the IP address that designates the specific device on a particular network ** IP address must have a subnet mask to be properly read. The subnet mask tells the router which bits are ‘network’ bits. The ‘count’ of network bits is also known as its CIDR (Classless InterDomain Routing) prefix IP addresses are identified by classes. The class is identified by the value of the 1 st octet: Class Binary Decimal 1 st octet 2 nd octet 3 rd octet 4 th o c t e t CIDR A 0 - - - - - - - 1 – 126* Network Host Host Host /8

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
