Hi Karol. If I understand you correctly, the choice of address to use is up to you and how it works best in your network. The DNS service addresses only need to be relevant to the network they sit in and the clients that need to reach them. In a private network, any 10 etc. address would work, as long as it can be routed. On the public Internet, obviously they need to be Internet-routable addresses.
I used to run internal resolvers that used anycast. Each one advertised the same two /32 and two /128 addresses, attached to loopback interfaces, routed into the boxes via their connected interfaces, which were all unique. The network ingested multiple versions of the loopback addresses, for which it needed a routeing protocol that supported ECMP. OSPF is an obvious choice but BGP also works if configured correctly. A search for "anycast rfc" finds a few IETF documents that discuss anycast generally. Does that help?
