If you are to attend personal necessity, please go silently and please be back. Drinks and foods are authorized. Mobile phones should be in silent mode Safety Guidelines What is an IP Address?  IP addresses are an important part of the Internet.  An IP address is a unique address that locate a device on the internet or a local network.  IP stands for "Internet Protocol," which is the set of rules governing the format of data sent via the internet or local network. IP Addresses Structure Currently, there are 2 versions of IP addresses in use i.e IPv4 and IPv6: 1. IPv4 (Internet Protocol Version 4)  It is the first version of the Internet Protocol address.  The address size of IPv4 is a 32-bit number.  It has 4,294,967,296 addresses IP Addresses Structure 2. IPv6 (Internet Protocol Version 6)  It is the recent version of the Internet Protocol address.  The address size of IPV6 is 128-bit number.  It allows 3.4 x 10^38 unique IP addresses which seems to be more than sufficient to support trillions of internet devices present now or coming in future. IP Addresses Structure Binary and IPv4 Addresses  Binary numbering system consists of 1s and 0s, called bits  Decimal numbering system consists of digits 0 through 9  Hosts, servers, and network equipment uses binary addressing to identify each other.  Each address is made up of a string of 32 bits, divided into four sections called octets.  Each octet contains 8 bits (or 1 byte) separated by a dot.  For ease of use by people, this dotted notation is converted to dotted decimal.  Binary Positional Notation The binary positional notation system operates as shown in the tables below.

NAT is typically enabled on the edge router connecting to the internet. It translates the internal private address to a public global IP address. Network Segmentation Check on Learning Summary  Discussed the Internet Protocol Addressing.  Determined the IPv4 Address Structure.  Identified the types of IPv4 Addresses.  Described the Network Segmentation.  Assessment Written Examination Twenty (20) items 1 point each. The exam will be Multiple Choice (Single Response). Students must attain a grade of 70% to pass the exam. Learning Outcome By this time, students are now able to define IP addressing and explain its purpose in network communication in accordance with Cisco Certified Network Associate (CCNA) v7, Introduction to Networks. Future Next lesson will be “Routing Fundamentals”. End of Presentation
