  1. IPv6 Address Structure

  2. :: can be used once to represent a string of zeroes

  3. From Zytrax: link IPv6 10

  4. IPv6 - IPv4 Addresses • A hybrid format may be used when dealing with IPv6 - IPv4 addresses where the normal IPv4 dotted decimal notation may be used after the first 6, 16 bit address elements:

  5. Examples

  6. Multiple Addresses • Note: Interfaces normally have two addresses, or even more • Link-local FE80::w.x.y.z • Global unicast

  7. Used by Ethernet

  8. Example Interface MAC 00-40-63-ca-9a-20 IPv6 Interface ID (EUI-64) ::0040:63FF:FECA:9A20 or ::40:63FF:FECA:9A20 link local FE80::40:63FF:FECA:9A20

  9. Version IHL Type of Service Total Length Version Traffic Class Flow Label Identification Flags Fragment Offset Payload Length Next Header Hop Limit Time to Live Protocol Header Checksum Source Address Source Address Destination Address Options Padding Destination Address IPv4 and IPv6 Header Comparison IPv4 Header IPv6 Header Field’s Name Kept from IPv4 to IPv6 Fields Not Kept in IPv6 Name and Position Changed in IPv6 New Field in IPv6 Legend

  10. AAAA Records in DNS • iana.org and ipv6.net work too

  11. In CNIT 202E - Link IPv6 1

  12. IPv6 Address Types

  13. IPv6 Address Types

  14. IPv6 Address Types • From ICANN (Link L2a)

  15. 90% of this talk is stolen • I got it here • CNIT 202E, link IPv6 8
