Ways to validate IP address

Question

Hi What ways are there to validate the ip address when login from different ip address rather than previous address. Example : when login to the google account it will send the notification like you are logged in from another device. Thanks in advance.

Hi Lokesh You need to store all ip history in your database and need to check every time while login. You can find ip address in c# uising following code. string hostName = Dns.GetHostName(); Console.WriteLine(hostName); string myIP = Dns.GetHostByName(hostName).AddressList[0].ToString(); Console.WriteLine( My IP Address is : +myIP); Console.ReadKey(); Mark as answer if you find helpful.
