Vijay, I think it's been safe to say for many years that *all* IP addresses, of either family, are transient, with limited exceptions (i.e. stable servers). I don't see that IPv6 autoconf addresses are qualitatively different in that respect. It is a deep design bug that when applications obtain

Are IPv6 auto-configured addresses transient?

Hi Everyone, Is there a notion that auto-configured IPv6 addresses based on globally unique prefixes are transient compared to manually configured ones? I know that we could configure them to have infinite lifetimes & such, but I am thinking of a large IPv6 deployment where these addresses are expe
