What it means

The virtual machine asks the DNS servers the Mac asks. This Mac's network names none that has an IPv4 address (a router that advertises only an IPv6 one, for example), and an IPv6 resolver of the Mac cannot be reached across the machine's NAT. The machine's gateway does not answer DNS, so zbx puts 1.1.1.1 (Cloudflare) and 8.8.8.8 (Google) before it, and the machine's name lookups, such as a pull's, go to them. A Mac with an IPv4 DNS server never does this.

To keep the lookups on your own network, join one that has an IPv4 DNS server, then zbx vm stop; the next command starts a machine that asks it. The warning is printed once, by the command that starts the machine.
