The below is useful info for when we start working on our support for 
IPv6...

Hi Max,

I really hate to use [xyz] anywhere I'd like to use literal IPv6 address. IP address should be always without brackets! On the other hand, URL need brackets because URL port (+ password) delimiter is the same as IPv6 IP's group delimiter - in this case [] are needed in _every_ case, but again - only when we are using _literal_ IPv6 address, not name. In an URL brackets are important to use because ambiguity can be occurred very easily.

I hate the present (only one) possible option as ./standalone.sh ... -b [IPv6] -bmanagement=IPv6 because it is really bad and at least unprofessional... in every case we'd like to specify literal IP address, we should do this _only_ without bracket, because this is only one possible text representation...

I guess, my thought isn't accepted by majority up to now (as we can see in present AS7), but I'd like to bet future is mine...:)

Pavel
