Jeremy’s IT Lab: Introduction to IPv6

Overview

• Free, complete course for CCNA
• Focus on IPv6, following IPv4 coverage
• Importance of transitioning to IPv6 as networks evolve
• Key topics: IPv6 addressing & prefixes (configuration and verification), comparison of IPv6 address types, and static routes in IPv6

Importance of IPv6

• IPv6 is the future due to IPv4 address exhaustion
• IPv4 has about 4 billion addresses (32 bits), insufficient for modern needs
• IPv6 has 128 bits, offering a vast number of addresses
• IPv6 address: 340 undecillion addresses

Understanding Number Systems

Hexadecimal

• Essential for IPv6 as addresses are written in hexadecimal
• Base 16, using digits 0-9 and A-F

Binary and Decimal

• Binary (base 2) with digits 0 and 1
• Decimal (base 10) with digits 0 to 9
• Essential to convert between these for understanding IPv6

IPv6 Address Representation

• Written using 32 hexadecimal characters
• Consists of 8 groups of 4 hex characters, separated by colons
• Abbreviations allowed:
  • Remove leading zeros
  • Use double colons for consecutive groups of zeroes (only once per address)

Conversion Practice

• Binary-to-hexadecimal and vice versa
• Importance of understanding binary for network calculations

Transitioning to IPv6

• IPv4 address exhaustion: IANA and RIRs running out of IPv4 addresses
• Techniques like NAT and VLSM are temporary solutions
• IPv6 offers a long-term solution with ample address space

IPv6 Basics

• 128-bit address structure
• Conventional /64 prefix length
• IPv6 addresses have network and host portions
• Global unicast addresses are the standard networked addresses

Configuring IPv6 on Cisco Devices

• Enable IPv6 routing with IPV6 UNICAST-ROUTING
• Configure addresses using IPV6 ADDRESS
• Link-local addresses automatically assigned

Practice Questions

• Identifying valid IPv6 addresses
• Shortening and expanding IPv6 addresses using abbreviation rules
• Calculating network prefixes from host addresses

Quiz and Practice

• Practice converting and configuring IPv6 addresses
• Supplementary materials available: Anki flashcards, Packet Tracer labs
