dns-client#

A DNS stub resolver over the guest's UDP stack. It sends an A query to the configured nameserver and prints every IPv4 address in the reply.

The example keeps DNS policy explicit: the caller selects the resolver and the name, while Dns_client_mirage handles request encoding, retries, and response decoding. It is the useful starting point for adding name resolution to a network appliance without a Unix resolver.
