They're not rogue; they're intended for IPv6 anycast DNS service. The RFC in
question is expired, though, and these days, DHCPv6 is probably the most
common way of configuring DNS for IPv6.
I didn't think they came in the list if you actually had any other DNS
servers (e.g., via DHCPv6), but I might be mistaken.
