Hi, Dominik,

What's removed is the corresponding text, not the bits. See page 19 of
RFC 4861: the bits are still there.

I'm curious about why the corresponding text was removed. In particular
when at the time (2007) the DNS options was not yet widely implemented,
and hence you *needed* DHCPv6 to learn the addresses of recursive DNS
servers dynamically.

Thanks,
