IPv6 privacy extensions can cause issues by preferring a temporary network over a public one. This preference may limit connectivity in certain situations. An example of a connectivity issue can be seen where the command ``traceroute6`` fails or misses all hops while other traffic to a given domain with a "AAAA" record may succeed. To resolve this issue the IPv6 privacy extensions have been disabled.
