Sure… You have to maintain the tunnel or they may reassign/reallocate the address. Here’s the reality of that, however: 1. Unless you care about reaching the customer they reassigned it to from your network, you don’t care. 2. Using it for ULA in addition to the tunnel isn’t really pro

Once again, you’re talking about usability of the addresses for internet connectivity. I don’t understand the relevance since we’re talking about a GUA based substitute for ULA. What am I missing? Owen > On Mar 2, 2018, at 1:29 PM, Bryan Holloway wrote: > > Another problem with tunnel broke

Not sure if this is the common thought, but if anyone has a network which requires static IP assignments, they can probably justify a request for a /48 from an RIR. After all, ARIN's requirement for an end-user IPv6 block is, at minimum: "Justify why IPv6 addresses from an ISP or other LIR are uns
