-DnsOnly

Resolves this query using only the DNS protocol.

-DnssecCd

Sets the DNSSEC checking-disabled bit for this query.

-DnssecOk

Sets the DNSSEC OK bit for this query.

-LlmnrFallback

Allows falling back to the LLMNR protocol when resolving this query with DNS fails.

-LlmnrNetbiosOnly

Resolves this query using only the LLMNR or NetBIOS protocols.

-LlmnrOnly

Resolves this query using only the LLMNR protocol.

-Name<String>

Specifies the name to be resolved.

-NetbiosFallback

Allows fallback to the NetBIOS protocol when resolving this query with DNS fails.

-NoHostsFile

Skips the hosts file when resolving this query.

-NoIdn

Specifies not to use IDN encoding logic for the query.

-NoRecursion

Instructs the server not to use recursion when resolving this query.
