The problem with variable-length addressing that, in practice, one needs
to specify a maximum length.

In some practical terms, perhaps, but there are extensibility schemes that allow the payload (addressing bits, in this case, to go on forever, in theoretical terms.

I look forward to your design for a forwarding plane based on streaming addresses :)

Does anyone really think that we'll need more than 128 bits?


You might have missed my opening qualification by refererring to practical terms as an actual limit?

I was responding to a comment about design limitations; I wasn't recommending infinite-length addressing.

I wasn't being as theoretical as one might assume. Although I had no direct hands-on, some of the folks on this list did:
