Hi All,
We're pushing to get IPv6 deployed and working everywhere in our operation, and I had some questions about best practices for a few things.
On your management nets (network device management nets) , what's the best approach for addressing them? Do you use ULA? Or do you use global addresses and just depend on router ACLs to protect things? How close are we to having a central registry for unique local addresses, and will that really happen?
What if you apply to a /48 block as end-user because the management network is not part of your ISP-related /32 or larger block ? What if you happen to get that /48 and never announce it to the DFZ ? Then your attack surface gets very small (but still exists, you'll need some ACLs here and there, notably your customers having default-routes to your core). Rubens
