DNS data and the transport layer
nIn principle the transport layer does not have influence on DNS data;
uData can be published by servers running on IPv4 or IPv6, content should not differ
uTransition problem: IPv6 client might not be able to see IPv6 servers and vice verse
uTransition problems are by far not solved
nException to above: IPv4 mapped addresses
uMapping is depended on OS libraries
