(If you think that there is something important missing or not working as you expect, feel free to post an issue on GitHub) doing a reverse lookup of an IP address to get the hostnameДЄnd then querying for all IPv4 and IPv6 addresses of that hostname.ДЇor some of those more commonly used things, this DNS client comes with a default implementation. Some queries might involve more complex business logic to get the results we actually want, e.g. Var host = await client.QueryReverseAsync(ip) Extended Query API Var result = await client.QueryAsync('', QueryType.MX) Var host = await client.QueryReverse(ip) Var result = client.Query('', QueryType.MX)

Synchronous and Async APIsДЄsync and sync API implementations are available for all query API methods. See also the resolve service methods below. Answers.OfRecordType(ResourceRecordType.HINFO)Д¬onsole.WriteLine($'Cpu: ')

The following is another example for how to manual cast and then access the resource record type specific data. Now, the Address property is available and can be used:ДЇoreach (var aRecord in client.Query('', QueryType.A).Answers.ARecords()) The ARecords extension method filters all A records from the answers collection, and casts them to ARecords. The corresponding ARecord class stores the IP address in the Address property.

To make that process a little bit easier, DnsClient comes with some build in extension methods for the most common types.ДЄn A record for example always only provide an IP address. Which means, to get to the QueryType specific data, each result record must be cast to the actual type. Resource record collections of the LookupClient's query result are typed with the base class of all resource records, Therefore, resource records in DnsClient also have very different properties to access the data. Var result = client.Query('', QueryType.A) Resource Record Specific TypesД®ach type of resource record transports very specific and different data which needs custom parsing. The following example queries for all A resource records: You have to provide a QueryType and optionally a Querењњlass in addition to a valid domain name. Run standard DNS queries for a domain name. The LookupClient's Query and QueryAsync methods can be used to Throw new ArgumentNullException(nameof(client)) Public SomeController(ILookupClient client) Which can be consumed later by some MVC Controller for example: IDnsQuery instead of the concrete implementation.

Var endpoint = new IPEndPoint(IPAddress.Parse('127.0.0.1'), 8600) ДЇor mock friendly and easier to test code and usage with injection (DI), it is recommended to have implementers The following code initializes a new lookup client using your local network DNS server(s).Д«ut you can also specify a custom DNS server running on any port:

That being said, the lookup client is thread safe, which means it can be used in a multithreaded and/or async context Otherwise, features like result cache and connection pooling will not have any effect which can decrease the application's performance. It is important to note, that it is highly recommended to instantiate the lookup client only once per applicationДЄnd to always use the same reference (singleton).

Methods to run DNS queries and reverse lookups. The LookupClient class is the main tool of this library.
