7.1 IPv4 Community Addresses

Binary and Decimal Conversion

• IPv4 Addresses

• • Particular Consumer IPv4 Addresses
    • Loopback addresses
      – 127.0.0.0 /8 or 127.0.0.1 to 127.255.255.254
    • Hyperlink-Native addresses or Computerized Non-public IP Addressing (APIPA) addresses
      – 169.254.0.0 /16 or 169.254.0.1 to 169.254.255.254
    • TEST-NET addresses
      – 192.0.2.0/24 or 192.0.2.0 to 192.0.2.255
  • Classless Addressing
    • CIDR
    • Allotted IPv4 addresses primarily based on prefix size
  • Task of IP Addresses

7.2 IPv6 Community Addresses

IPv4 Points

• The Want for IPv6
  • Depletion of IPv4 deal with area
  • Web of Every part
• IPv4 and IPv6 Coexistence
  • Twin Stack – IPv4 and IPv6 on the identical community
  • Tunneling – IPv6 packets inside IPv4 packets
  • Translation – IPv6 packet is translated to an IPv4 packet, and vice versa.

IPv6 Addressing

• IPv6 Deal with Illustration
  x:x:x:x:x:x:x:x, the place x represents 4 hexadecimal values
• Apply the principles to easily these IPv6 Addresses
  • Rule 1: Omit Main 0s
  • Rule 2: Omit All 0 Segments
    • 2001:0DB8:0000:1133:0000:0000:0000:0200
    • 2001:0DB8:CAFE:0000:1111:0000:0000:0200
    • 2001:0DB8:000A:0000:0000:0000:0000:1000
    • 2001:0DB8:ACAD:1234:0000:0000:0000:0000
    • 2001:0DB8:0000:1111:0020:0000:ACAD:0000
    • FF02:0000:0000:0000:0000:0000:0000:0001
    • FE80:0000:0000:0000:0000:0000:0000:0003
    • 0000:0000:0000:0000:0000:0000:0000:0000

Forms of IPv6 Addresses

• • IPv6 Deal with Varieties
  • IPv6 Prefix Size
    • Signifies the community portion
    • Format: IPv6 deal with /prefix size
    • Prefix size vary from 0 to 128
    • Typical size is /64

• Widespread Forms of IPv6 Addresses
  • • Unicast Addresses
      – Distinctive, Web routable addresses
      – Configured statically or assigned dynamically
    • Hyperlink-Native Unicast Addresses
      – Talk with different IPv6 enabled gadgets on the identical hyperlink
      – Gadget creates its personal hyperlink native deal with with out DHCP server
    • Distinctive Native Addresses
      – Distinctive native unicast
      – Used for native addresses inside a web site or between a restricted variety of websites

  

IPv6 Unicast Addresses

• Construction of an IPv6 World Unicast Deal with
  • World Routing Prefix
  • Subnet ID
  • Interface ID
• Static Configuration of a World Unicast Deal with
  • ipv6 deal with ipv6-address/prefix-length
• Dynamic Configuration
• Hyperlink-Native Addresses
• Verifying IPv6 Deal with Configuration
  • present ipv6 interface transient

IPv6 Multicast Addresses

• Assigned IPv6 Multicast Addresses
  • IPv6 multicast addresses have the prefix FF00::/8
    – FF02::1 All-nodes multicast group
    – FF02::2 All-routers multicast group

  

• Solicited-Node IPv6 Multicast Addresses

7.3 Connectivity Verification

ICMP

• ICMPv4 and ICMPv6
  • Host Affirmation
  • Vacation spot or Service Unreachable
  • Time Exceeded
  • Router Redirection
• ICMPv6 Router Solicitation and Router Commercial Messages
  • Messaging between an IPv6 router and an IPv6 gadget:
    • Router Solicitation (RS) message
    • Router Commercial (RA) message
  • Messaging between IPv6 gadgets:
    • Neighbor Solicitation (NS) message
    • Neighbor Commercial (NA) message
  • Duplicate Deal with Detection (DAD)

Testing and Verification

• Ping
  • Testing the Native Stack
    – 127.0.0.1 (IPv4) or ::1 (IPv6)
  • Testing Connectivity to the Native LAN
  • Testing Connectivity to Distant
• Traceroute
  • Testing the Path
    – Spherical Journey Time (RTT)
    – IPv4 TTL and IPv6 Hop Restrict

7.4 Chapter Abstract

Abstract

• Clarify using IPv4 addresses to offer connectivity in a small to medium-sized enterprise community.
• Configure IPv6 addresses to offer connectivity in small to medium-sized enterprise networks.
• Use widespread testing utilities to confirm community connectivity.
