Even though I may have been vague with the numbers and specifics, does it help shed any light on how we might struggle to fit into a /29 allocation? In many respects, for us I feel that the fact there are >500k /48's in a /29 is similar to the fact that a /64 subnet has 2^64 addresses within it - it doesn't necessarily mean what the figures might otherwise first suggest!

This makes me curious.

Your /29 is the equivalent of 8 IPv4 internets, if we ignore that /64 subnet thing.

How do you manage your IPv4 space, then? Do you actually have routing that needs more than 8 total IPv4 spaces?
