Important:

1. We recommend that you place your DNS servers on different networks.

2. Some top-level domain (TLD) zones may have specific network requirements for DNS servers. For example, in the .DE and .FR TLD zones, DNS servers must be placed on different networks. We recommend taking this into account when preparing your servers.
