 `cniVersion` specifies a [Semantic Version 2.0](http://semver.org) of CNI specification used by the plugin.
-The "dns" field contains a list of a priority-ordered list of DNS nameservers that this network is aware of.
-Each entry in the list is a string containing either an IPv4 or an IPv6 address.
-Typically this value would just be the value returned by the IPAM plugin.
-It is outside the scope of this specification how the container runtime uses the list of DNS nameservers from each of the networks to provide name resolution services to the container.
-Examples of how this list could be used include generating an `/etc/resolv.conf` file to be injected into the container filesystem or running a DNS forwarder on the host.
+`dns` field contains a dictionary consisting of common DNS information that this network is aware of.
+The result is returned in the same format as specified in the [configuration](#network-configuration).
+The specification does not declare how this information must be processed by CNI consumers.
