I was thinking of using this code to block access to public methods in my asp.net mvc application:
/// <summary>
/// Comma seperated string of allowable IPs with masks. Example "10.2.0.0;255.255.0.0,10.3.0.0;255.255.0.0"
/// </summary>
/// <value>The masked Ips.</value>
public string AllowedMaskedIPs { get; set; }
Excerpt taken from here.
But I was curious as to what is the difference between a masked ip and a single ip? Basically, what is a masked ip?
