or maybe you mean the user's searching if he needed to change that ip.
yes, if a user had nameservers a.ns.domain.dom, b.ns.domain.dom, and
c.ns.domain.dom, and wanted to change the ip all of these resolve to, he
would need to change each of these 1 by 1, at least given opensrs'
management interface. this would occur whether they had the same or
different ips -- there is no difference.
the root servers do not give ptr records (reverse dns) for registered
nameservers. no such conflicting would occur there.
i may have misunderstood the point of your above paragraph the first time
around. my apologies if so.
