ip-address

问题 I would like advice on the best way to restrict access to a weba pplication (using .net 2.0 and II6) based on the clients IP address. The two ways I am considering: 1) Through the server side code - check the client I.P against a list of IP addresses within the web.config. 2) Through IIS by creating a virtual directory and restricting the I.P addresses on this virtual directory. My question is if I go the virtual directory route there are a lot of users that access this website and I have

问题 I need to store persistent reference to third party device on an arbitrary IP network where the IP address of the devices may be static or randomly assigned by DHCP. I don't control the devices on the network and I can't rely on DNS and other ad-hoc networking protocols existing or working with the devices. So I have been instructed to investigate using hardware addresses and ARP. This will work but I don't want to duplicate code. The kernel must manage an ARP table. On Windows you can access

问题 I'm having a little trouble understanding the System.Net.IPAddress class, because I don't know where to look for a definition of what some of the properties are referring to. Specifically, what are: IPAddress.IsIPv6LinkLocal IPAddress.IsIPv6Multicast IPAddress.IsIPv6SiteLocal IPAddress.IsIPv6Teredo I will also happily accept an answer that points to a resource that explains these concepts. The MSDN site has proved insufficient. 回答1: IPAddress.IsIPv6LinkLocal A link-local address is an IP

问题 On which is running the WebService. Like the one I can get in cmd.exe > ipconfig : What I would like to achieve is automatic IP configuration of Kestrel, like: .UseKestrel(opts => { opts.Listen(/*LocalIPv4ActiveAddress*/, 5000); }) So I can switch my development machines with different active network interfaces (WiFi || Ethernet) and different local network IP addresses. 回答1: You can try something like this: // order interfaces by speed and filter out down and loopback // take first of the
