What's removed is the corresponding text, not the bits. See page 19 of RFC 4861: the bits are still there. > They don't even longer exist, but still > exist? 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.
