Public IPv4 and routed IPv6 /64 explained
Every VMBargain VM includes a routed IPv6 /64. A public IPv4 address is optional and must be selected in the configuration when the workload requires IPv4 reachability.
IPv4 and IPv6 are independent protocols: success over one does not prove the other works. DNS clients prefer addresses according to their own network and policy, so publish an AAAA record only after the service works over IPv6.
Useful checks
ip -4 address
ip -6 address
ip route
ip -6 route
curl -4 https://example.com/
curl -6 https://example.com/Do not copy example prefixes into the guest. OpenNebula supplies the assigned addressing through the selected image’s network context.
