IPv6 special addresses, such as Link Local Addresses, are IP addresses registered for specific reasons.

In this follow-up to last week’s episode IPv4 Special Addresses and IPv6 Adoption, Ed, Scott and Tom discuss IPv6 special address ranges, how they are used, and what to watch out for when using them.

Topics discussed include:

* Understanding the special IPv6 ranges, including the ones used in production networks

* Problems caused by the use of Unique Local Addresses (ULAs) and the operational circumstances where it’s OK to use them

* The special prefix reserved for DNS64/NAT64 and whether it should be used in production networks

* What IPv4-mapped IPv6 addresses are and when are they used
