How to IP Range Regular Expression Builder in C#

Hello Madan Sir,

 

                           i can required regex string builder, ip range i have already finded but start ip address and end ip address value on generate regex string.

https://www.c-sharpcorner.com/article/get-ip-address-in-Asp-Net/

 

using above link you will come to know how to get system ip adress 

public static bool IsInRange(string startIpAddr, string endIpAddr, string address)

{

long ipStart = BitConverter.ToInt32(IPAddress.Parse(startIpAddr).GetAddressBytes().Reverse().ToArray(), 0);

long ipEnd = BitConverter.ToInt32(IPAddress.Parse(endIpAddr).GetAddressBytes().Reverse().ToArray(), 0);

long ip = BitConverter.ToInt32(IPAddress.Parse(address).GetAddressBytes().Reverse().ToArray(), 0);

return ip >= ipStart && ip <= ipEnd; //edited

}

Console.WriteLine(IsInRange("100.0.0.1", "110.0.0.255", "102.0.0.4"));//true

 

 

true means valid incoming ip is fall under our ip range . false means failure
