DnsClient.NET

Build Status Code Coverage NuGet NuGet

DnsClient.NET is a simple yet very powerful and high performance open source library for the .NET Framework to do DNS lookups.

Usage

See the DnsClient site for more details and documentation.

The following example instantiates a new LookupClient to query some IP address.


var lookup = new LookupClient();
var result = await lookup.QueryAsync("google.com", QueryType.A);

var record = result.Answers.ARecords().FirstOrDefault();
var ip = record?.Address;

Features

General

  • Sync & Async API
  • UDP and TCP lookup, configurable if TCP should be used as fallback in case the UDP result is truncated (default=true).
  • Configurable EDNS support to change the default UDP buffer size and request security relevant records
  • Caching
    • Query result cache based on provided TTL
    • Minimum TTL setting to overrule the result's TTL and always cache the responses for at least that time. (Even very low value, like a few milliseconds, do make a huge difference if used in high traffic low latency scenarios)
    • Maximum TTL to limit cache duration
    • Cache can be disabled
  • Nameserver auto discovery. If no servers are explicitly configured, DnsClient will try its best to resolve them based on your local system configuration. This includes DNS servers configured via network interfaces or even via Windows specific NRPT policies.
  • Multiple DNS endpoints can be configured. DnsClient will use them in random or sequential order (configurable), with re-tries.
  • Configurable retry of queries
  • Optional audit trail of each response and exception
  • Configurable error handling. Throwing DNS errors, like NotExistentDomain is turned off by default
  • Optional Trace/Logging

Supported resource records

  • A, AAAA, NS, CNAME, SOA, MB, MG, MR, WKS, HINFO, MINFO, MX, RP, TXT, AFSDB, URI, CAA, NULL, SSHFP, TLSA, RRSIG, NSEC, NSEC3, NSEC3PARAM, DNSKEY, DS
  • PTR for reverse lookups
  • SRV for service discovery. LookupClient has some extensions to help with that.
  • AXFR zone transfer (as per spec, LookupClient has to be set to TCP mode only for this type. Also, the result depends on if the DNS server trusts your current connection)

dotnet-etcd

A C# .NET (dotnet) GRPC client for etcd v3+. etcd is a distributed key value store that provides a reliable way to store data across a cluster of machines. It’s open-source and available on GitHub. etcd gracefully handles leader elections during network partitions and will tolerate machine failure, including the leader. Your applications can read and write data into etcd. A simple use-case is to store database connection details or feature flags in etcd as key value pairs. These values can be watched, allowing your app to reconfigure itself when they change. Advanced uses take advantage of the consistency guarantees to implement database leader elections or do distributed locking across a cluster of workers.

SIPSorcery

Real-time communications library with full support for the Session Initiation Protocol (SIP) and WebRTC. No wrappers and no native libraries required.
