As DNS is "global" naming service, it is not too easy to integrate local
names such as site local or even worse - link local with it. Even if you
have to reconfigure your global names, it's major pain..... We had to
change our domain master server some years ago and it took about week to
get old address to vanish, for example. The problem at client side, I
think, is choosing the right address to make connection with - if host
has severall addresses - ipv4, ipv6 global, site local and link local,
the client resolver must not resolve adresses whicha are clearly not
reachable. I mean, if the target host is from different subnet, the
resolver must not give me link local adress. If the target is from
different site, resolver must not give site local etc. Just now I can
configure my naming service to include all addresses and this will work
as long as all hosts are reachable for all addresses.... but this all is
for resolving names and connecting to host. name registering and related
security is another issue...
