Here is the code with which you can play and explore the internet: string srv = null; do { Console.Write(Enter server name: ); srv = Console.ReadLine(); if (!string.IsNullOrEmpty(srv)) { try { System.Net.IPAddress[] addr = System.Net.Dns.GetHostAddresses(srv); for (int i = 0; i Console.WriteLine(Name: {0}; Family: {1}; Address: {2} srv addr[i].AddressFamily addr[i].ToString()); } catch (System.Exception ex) { Console.WriteLine(ex.Message); } } } while (!string.IsNullOrEmpty(srv)); I've tried several addresses and results are interesting: Name: www.microsoft.com; Family: InterNetwork; Address: 207.46.131.43 Name: ftp.microsoft.com; Family: InterNetwork; Address: 64.4.30.34 Name: ftp.c-sharpcorner.com; Family: InterNetwork; Address: 74.81.194.29 Name: www.c-sharpcorner.com; Family: InterNetwork; Address: 74.81.194.29 Name: www.sysexpand.com; Family: InterNetwork; Address: 66.96.146.89 Name: ftp.sysexpand.com; Family: InterNetwork; Address: 66.96.146.89 Name: www.oracle.com; Family: InterNetwork; Address: 46.33.68.118 Name: www.oracle.com; Family: InterNetwork; Address: 46.33.68.78 Name: ftp.oracle.com; Family: InterNetwork; Address: 141.146.44.21 You can see that large systems like microsoft.com and oracle.com hold FTP on different addresses. However smaller sites typically hosted for money at the ISP have same address of FTP and HTTP server. That is typical situation on the Internet and it is directed by actual traffic made over FTP and HTTP. Zoran

System.Net.IPAddress[] addr = System.Net.Dns.GetHostAddresses(www.sysexpand.com); for (int i = 0; i Console.WriteLine(Family: {0}; Address: {1} addr[i].AddressFamily addr[i].ToString()); This code produces output: Family: InterNetwork; Address: 66.96.146.89 This is read as IPv4 family address 66.96.146.89 Do not write protocol as part of the server name (ftp:// or http://) because that is not part of the server name - it only shows what protocol to use when communicating with the server.
