typedef basic_resolver_query< InternetProtocol > query;
| Name | Description | 
|---|---|
| A bitmask type (C++ Std [lib.bitmask.types]). | |
| The protocol type associated with the endpoint query. | 
| Name | Description | 
|---|---|
| Construct with specified service name for any protocol. Construct with specified service name for a given protocol. Construct with specified host name and service name for any protocol. Construct with specified host name and service name for a given protocol. | |
| Get the hints associated with the query. | |
| Get the host name associated with the query. | |
| Get the service name associated with the query. | 
| Name | Description | 
|---|---|
| Only return IPv4 addresses if a non-loopback IPv4 address is configured for the system. Only return IPv6 addresses if a non-loopback IPv6 address is configured for the system. | |
| If used with v4_mapped, return all matching IPv6 and IPv4 addresses. | |
| Determine the canonical name of the host specified in the query. | |
| Host name should be treated as a numeric string defining an IPv4 or IPv6 address and no name resolution should be attempted. | |
| Service name should be treated as a numeric string defining a port number and no name resolution should be attempted. | |
| Indicate that returned endpoint is intended for use as a locally bound socket endpoint. | |
| If the query protocol family is specified as IPv6, return IPv4-mapped IPv6 addresses on finding no IPv6 addresses. | 
          The ip::basic_resolver_query class template
          describes a query that can be passed to a resolver.
