Introduction

Internet Protocol and IPv4 Internet Protocol relies on reading the IP Addresses of packets. IPv4 was the first major version of IP.

IPV4’s Failings Eventually, every last address in IPV4 was allocated. Something had to change in order to accommodate the rapidly growing internet.

IPv6 vs. IPv4 Address Space 32 Bits long 128 Bits long

More on IPv6 Address IPv6 addresses are represented in hexadecimal The 128 bit address space offers a huge amount of addresses This large of an address block allows the designers to pack more information in a more organized way into the IP. Binary Dotted Decimal Hexadecimal Leading-Zero Suppressed Straight Hex Zero-compressed Mixed Notation

Additional Advantages of IPv6 Better for mobile users Stronger connection security Easier transfer of audio/video files

IPv6 Multicast Addressing 3 Types of Addresses Unicast Broadcast Multicast Multicast is build into IPv6 Multicast is made up of groups.

Datagram Structure IPv6 headers can hold more information because of the increased size of IPv6. Header was simplified since IPv4. Can add extension headers for greater flexibility

Hey, My unique number is 100 What?! I’m confused!! Unique IP Addresses

BOOTP (Bootstrap Protocol)

Server Searches BOOTP Table for Matching IP ADDRESS and MAC ADDRESS

Ok, so here is your IP address, my IP address, my name, and the IP address of the default router. BOOTP Server Sends IP ADDRESS and Other Requested Information

DHCP (Dynamic Host Configuration Protocol) Automated way of assigning an unique IP address Client Request from DHCP Server an “IP address to lease” Server receives request and sends offer to the client Client Responds to offer DHCP server sends packet acknowledging agreement

DHCP Server Leases IP Addresses from a Pool of IP Addresses

Client Requests an IP Address Can I have an IP address?

Server Sends Offer to the Client Sure, I reserved an IP address for you. You can use it for 18 hours. By the way, here is my IP Address.

Client Responds to Offer Thanks, I received your offer and I accept it

DHCP Server Sends Packet Acknowledging Agreement No problem! Here is the information you need in order to configure your settings

APIPA: DHCP’s Support Support for DHCP Acts as a backup when DHCP servers fail

APIPA And Addressing ARP: Address Resolution Protocol The inner mechanics of APIPA.
