IPv6 address/port format

[Wilfried Woeber, UniVie/ACOnet]

=> 	Is that port 143 on system 130.205.1.0 (host 1.0 on network 130.205)
=> or is that host 130.205.1.143?  It's a rare case, but legitimate.  In
=> IPv4 notation they allow 130.20.1 to be the equivalent of 130.205.1.0 in

=I think you mean 130.205.0.1...

=[sloth]:~$ telnet 10.1
=Trying 10.0.0.1...

  That's exactly why we should avoid room for (different) interpretations.
  
  "Everyone" in the routing world would read(expand) 10.1 as 10.1.0.0/16 :-)
  and I suppose most of the tools (other than your telnet :-) would expand
  that to 10.1.0.0/32 ....
