Spicial subject final

  1. 1. Special SubjectIPv6 Addressing<br />Morten Jørgensen<br />2. semester Network<br />
  2. 2. Overview<br />Addressing<br />Unicast (Individual)<br />Multicast (Group)<br />Anycast (Selective )<br />Required Addresses and Address Selection<br />Real World Address<br />Demo <br />Questions<br />
  3. 3. Addressing Essentials<br />DNS is important <br />Manual typing<br />sequence of all-zero groups can be replaced by pair of colons <br />Loopback address = 0:0:0:0:0:0:0:1 = ::1<br />IPv6 supports three different address types for which the delivery process varies:<br />Unicast (individual)<br />Multicast (group) ( Broadcast ) (ff02::1)<br />Anycast (selective)<br />
  4. 4. Unicast<br />This is the most important address type because unicast addresses are the “normal” addresses identifying the common computers, printers and other devices connected to the network.<br />Unicast is defined in RFC 3587<br />The unicast address structure contains just three parts - global routing prefix, subnet ID, and<br />interface ID.<br />Not all unicast addresses are global. Some of them are limited just to a single physical (layer 2) network.<br />
  5. 5. Multicast <br />There is a separate part of the IPv6 address space dedicated to multicast. It is identified by the prefix ff00::/8. So every multicast address starts with “ff” which makes them easy to distinguish.<br />
  6. 6. Anycast<br />There is no separate part of the address space dedicated for Anycast<br />Anycastare living in the unicastspace<br />Security<br />How do we protect anycast groups from intruders falsely declaring themselves to be holders of given anycast addresses and stealing the data or sending false responses<br />
  7. 7. Required Addresses and Address Selection<br />Every interface has just a single address in IPv4.<br />IPv6 is different. ( More addresses to same netcard ) <br />
  8. 8. Real-world Addresses<br />
