        <clear />
        <add ipaddress="127.0.0.1" allowed="true" /> 
        <add ipaddress="192.168.78.0" subnetmask="255.255.255.0" allowed="true" />
        <add ipaddress="193.167.89.0" subnetmask="255.255.255.0" allowed="true" />

Have you read this: http://www.stokia.com/support/misc/web-config-ip-address-restriction.aspx[^]?

This settings is handled by IIS, thus if the user ip is blocked, your code will never got notified.

1. Import library as:

C#

Import System.Configuration

2. Read config data as:

C#

string configIP1 = ConfigurationManager.AppSettings["ip1"];

3. Validate with user input as:

C#

string user_input = txtUserInput.txt
if(user_input.Equals(configIP1))
{
//Valid ip entered
}
{
//Invalid ip entered
}

I hope this is what you are looking for...

Hope this will help you.

The IPSecurity tag will be work only if IIS manager Role Service is configuered like

http://www.iis.net/configreference/system.webserver/security/ipsecurity/add#006[^]

But we can't configure this for windows xp or any client machine.

It can be done only in windows server2008 and vista.

So we can add list of ip address as

XML

<appSettings>
    <add key="RestrictIPAddress" value="192.168.78.0 to 192.168.78.50,193.167.89.0 to 193.167.89.50"/>
  </appSettings>

with this name we can able to check ip address.
