Fix #1100: scenarios with -6 and --ip=<ipv6address>

Browse Source 
This PR fixes checks where those two cmdline options were supplied
but errorneously also the IPv4 address was tested.

It also lables supplied IPv6 addresses as AAAA records
instead of A records.

Still, determine_ip_addresses() has space for improvements.

Some comparisons fixed strings popped up during debugging were polished
to avoid internal quoting

[[ $VAR == "teststr" ]]

will be otherwise expanded to

[[ $VAR == \t\e\s\t\s\t\r ]]
