Soenneker.DnsClient.Util

Provides a lazily initialized, cached DnsClient.NET LookupClient through dependency injection.

Installation

dotnet add package Soenneker.DnsClient.Util

Registration

using Soenneker.DnsClient.Util.Registrars;

services.AddDnsClientUtilAsSingleton();

Use AddDnsClientUtilAsScoped() when each dependency-injection scope should own a separate lookup client and cache.

Query a record

using DnsClient;
using DnsClient.Protocol;
using Soenneker.DnsClient.Util.Abstract;

public sealed class AddressResolver(IDnsClientUtil dnsClientUtil)
{
    public async Task<IReadOnlyList<string>> Resolve(
        string host,
        CancellationToken cancellationToken)
    {
        LookupClient client = await dnsClientUtil.Get(cancellationToken: cancellationToken);
        IDnsQueryResponse response = await client.QueryAsync(
            host,
            QueryType.A,
            cancellationToken: cancellationToken);

        return response.Answers.ARecords()
                       .Select(record => record.Address.ToString())
                       .ToArray();
    }
}

Get returns the same LookupClient for the utility’s lifetime. The first successful call controls its options; options supplied to later calls are ignored.

Configure the client on the first call when system DNS defaults are not appropriate:

var options = new LookupClientOptions
{
    UseCache = true,
    Timeout = TimeSpan.FromSeconds(3),
    Retries = 2
};

LookupClient client = await dnsClientUtil.Get(options, cancellationToken);

For singleton registration, initialize it once during startup if multiple callers might otherwise race to provide different settings. DnsClient.NET handles DNS response codes and transport failures; inspect the returned response and allow cancellation or network exceptions to propagate when the caller should decide recovery behavior.

The utility owns the cached client. Do not dispose the returned LookupClient; dispose the utility or its dependency-injection scope instead.
