dns_servers = 203.0.113.8, 198.51.100.53
OVN answers queries for hosts and IP addresses in tenant networks by spoofing
responses from the configured DNS servers. This may lead to confusion in
debugging.
OVN can only answer queries that are sent via UDP, queries that use TCP will be
ignored by OVN and forwarded to the configured resolvers.
OVN can only answer queries with no additional options being set (EDNS). Such
queries depending on the OVN version will either get broken responses or will
also be forwarded to the configured resolvers.
* IPv6 NDP proxy
The NDP proxy functionality for IPv6 addresses is not supported by OVN.
* Metadata via IPv6
The OVN metadata agent currently does not allow access via IPv6.
