You don't need a third party service to be able to do this. flags: qr rd ra QUERY: 1, ANSWER: 6, AUTHORITY: 0, ADDITIONAL: 0 >HEADER<<- opcode: QUERY, status: NOERROR, id: 53737 The results returned look like: > Dig.Net 0.0.1 > A The output goes straight to the console but you could modify to parse the results into return values.Īdding a reference to the project I was able to do this: Dig dig = new Dig() ĭig.DnsResolver = new Resolver("8.8.8.8") If you want to specify your own resolver then use the Dig tool I mentioned above. The above methods will query the DNS servers as specified in the computer's own network settings. IPAddress GetHostAddresses(string hostNameOrAddress) IPHostEntry GetHostEntry(string hostNameOrAddress)

There's a couple of static methods you could use: NET's built in capabilities you can use the System.Net namespace and the Dns class. DNS Lookup is an online tool that will find the IP address and perform a deep DNS lookup of any URL, providing in-depth details on common record types, like A, MX, NS, SOA, and TXT. There's plenty of free DNS services such as Google or OpenDNS you can use as nameservers. I've used this one in the past and it works pretty well. Use our nslookup utility to grab dns records, including mx records.Do global domain searches, look up internic whois records, and query the arin database with our automatic whois lookup.Use our software tools to do ip address lookups and reverse lookups. nslookup for and works but nslookup for any outside names don't work and login onto adminportal fails. However there are a one or two dig type C# implementations such as: Check your network path with our simple visual traceroute.Use our icmp ping and traceroute to check your servers. You don't say exactly what you want to be able to do.
