ProblemYou have an IP address that you need to resolve into a hostname. SolutionUse the Dns.Resolve method to get the hostname for an IP address. In the following code, an IP address is passed resolved, and the hostname is printed to the console: using System; using System.Net; //... // use the Dnss class to resolve the address IPHostEntry iphost = Dns.Resolve("127.0.0.1"); // HostName property holds the hostname string hostName = iphost.HostName; DiscussionThe System.Net.Dns class is provided for simple DNS resolution functionality. The Resolve method returns an IPHostEntry that can be used to access the hostname via the HostName property. See AlsoSee the "DNS Class" and "IPHostEntry Class" topics in the MSDN documentation. |
