Comparing IPv6 address types

IPv6 does not use a broadcast as in IPv4. However, there are several types of addresses, as listed here:

  • Global Unicast is like a public IPv4 address. The address is globally recognized and can be routed on the internet.
  • Link local is used to communicate with hosts on the same sub-network. This address always starts with FE80.
  • Unicast is a single host on a network.
  • Multicast packets are delivered to all nodes on a network using a single multicast address.
  • Anycast is used to send data to multiple locations with the same IP address. The packets are delivered to the closest (or nearest) destination.

In frame 347, we see the source and destination addresses: 

Source: fe80::9186:dbbd:2a45:50c2
Destination: ff02::1:2

When possible, Wireshark will use appropriate shortcut methods, as shown in the destination address. An IPv6 shortcut removes leading zeros and collapses two or more blocks that contain consecutive zeros. 

For many, but not all, protocols, Wireshark provides a means to modify the way in which Wireshark presents the data. The following gives us some insight of how to adjust preferences for both IPv4 and IPv6.
