Re: Variable length internet addresses in TCP/IP: history

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?

The result, therefore, is that you don't
have variable-length addresses at all but rather fixed-length addresses
with a shorthand encoding for unused bits.

For most variable-length schemes, yes, but not all.
