Check Ip Address Against A Range Of Values Using C#?
Dec 14, 2010
We are writing a feature that allows an administrator to block/allow ranges of ip addresses.
Is this easy enough to do with c#?
I was thinking of looking at each number [here].[here].[here].[here] and then mathing it with the ranges and just seeing if each number was between the two?
Will that work for standard ip v4 addresses?

If we let users input a couple of ip ranges, e.g., 172.16.11.5 - 100, how could I write a fucntion to check if a IP (172.16.11.50) falls in the ranges?
Is there any existing library in .NET to leverage?

I have the following code. What's happening is, on postback, the required attribute for sequence will fire. If it passed, the range check is skipped completely. If it fails, it never gets to the range check either. Have I coded something wrong?
using System.ComponentModel.DataAnnotations;namespace Venue.Models{ [MetadataType(typeof(CategoryMetadata))] public partial class Category { } public class CategoryMetadata { [Required(ErrorMessageResourceType = typeof(Resources.Locale), ErrorMessageResourceName = "sequence_required")] [Range(0, 9999, ErrorMessageResourceType = typeof(Resources.Locale), ErrorMessageResourceName = "sequence_invalid")] public int Sequence { get; set; } [Required(ErrorMessageResourceType = typeof(Resources.Locale), ErrorMessageResourceName = "title_required")] [StringLength(256, ErrorMessageResourceType = typeof(Resources.Locale), ErrorMessageResourceName = "title_invalid")] public string Title { get; set; } }}

Our logs show hundreds of these errors after our deployment if users are on the site. Anyone know what this means and how to fix it?
Notes:
We are using msdeploy, IIS 6 I recently noticed that our web server's time is about 10 minutes behind the real time, I think that may have something to do with it.
If I log into our site, seems like any file that depends on a WebResource or ScriptResource type file doesn't look right.

I have a form with x fields on - its a signup form on a web page. I use standard validation controls which I use for validating on both client and server side, however I have an additional requirement I don't think is covered by the standard controls. When a user enters an email address and press enter, I validate that the address is not already in the database, by calling a stored procedure. This works fine but it would be great to validate it client side as with all the other entry fields.
I wouldn't know where to start with javascript so I have come up with the following solution. I have put a ontextchanged event on the email textbox and set to autopostback. When the user navigates away from the textbox validation is called and this seems to work ok. My question is have I missed something, and is there an easier soluyion using validation controls or is this an appropriate solution to the problem?

How can I check if an email address actually exists?
I have a list of email addresses which I want to screen for dead email accounts (without sending an email msg with a hyperlink). Is there a web-service for this? Or C# code (which I prever instead of sending the data to someone else)?
