ip-address

问题 Is there a way to get the number of IPv6 addresses from a Ipv6 CIDR? for example: CIDR: 2403:3E00::/32 => need get number of ipv6 addresses: 79228162514264337593543950336 回答1: An IPv6 address has 128 bits, of which (slightly simplified) a number are dedicated to network address, and the rest are dedicated to host addresses. In your case, 32 bits are dedicated to the network part ( /32 ), so the other 96 are dedicated to host addresses. 2^(128-32) = 2^96 = 79228162514264337593543950336 hosts

问题 I'm building a small application that will change your IP address after you type it into a masked text box. I'm really close to figuring it out, but I need help with the h = myNewIP part, as I can't convert from an IP address to an IP Host Entry : Public Class MainForm Dim h As System.Net.IPHostEntry = System.Net.Dns.GetHostEntry(System.Net.Dns.GetHostName) Dim myNewIP As System.Net.IPAddress Dim myIPEndPoint As System.Net.IPEndPoint Dim strLocalIp As String Private Sub myNewIP = System.Net

问题 I've my ruby on rails website registered as a subdomain under godaddy.com It works fine. But when I try to get the window.location.host, It returns the IP address of my server and not the domain name. Because of this I'm getting the following error with my google picker js api: Incorrect origin value.

问题 I need to get the IP address of a WebSocket and compare it to other already connected WebSockets to prevent redundant connections because the list of server addresses for this application are retrieved from potentially malicious sources. I've examined the WebSocket object and the specification, and it appears that the url can be returned but not the IP. How can the IP be retrieved from the WebSocket connection in a browser? 回答1: AFAIK, there is no such way to get resolve IP from url, you may

问题 Background At the beginning of my program I build a linked list of adapter interface addresses using GetAdaptersAddresses. Later, after creating an ipv6 slaac address, calling Socket() , Bind() and Listen() all succeed where the IfType is Wireless, that is, IfType 71 ( IF_TYPE_IEEE80211 ). My filter parameters are family and ifType . I test by connecting and disconnecting the ethernet cable. For each case my software finds the active interface with said parameters: connected it finds ethernet

问题 Background: I am trying to get up to speed on using RFC7217 compliant ipv6 addresses. To that end I have written code that creates a valid route-able ipv6 address like 2600:8806:2700:115:c4a3:36d8:77e2:cd1e . I know I need to enter the new address into windows before being able to bind() to it. I figured that these two methods would do the trick. So, using one of my ip addresses, I executed the sample code found in CreateUnicastIpAddressEntry. Then, using the same ip address, I executed the

问题 I'm trying to put together a batch file, that will ping a website, and assign its ip to a variable - I've searched around, but haven't really been able to put something together. Can anyone shove me in the right direction. Tim. 回答1: You could try the ping command. The idea is to get the part between the [], of the ping output. @echo off setlocal EnableDelayedExpansion set myServer=google.de for /f "tokens=1,2 delims=[]" %%a IN ('ping -n 1 !myServer!') DO ( if "%%b" NEQ "" set ip=%%b ) echo ip

问题 I have the below for loop for ip in 10.11.{32..47}.{0..255} do echo "<ip>${ip}</ip>" done I want to exclude this iprange: 10.11.{32..35}.{39..61} from the above for loop. This ip range is a subset of the above one. Is there a way to do that? I tried this, this doesn't work: abc=10.11.{34..37}.{39..61} for ip in 10.11.{32..47}.{0..255} do if [[ $ip == $abc ]] then echo "not_defined" else echo "<ip>${ip}</ip>" fi done 回答1: Try this: for ip in 10.11.{32..47}.{0..255} do echo 10.11.{32..35}.{39.

问题 I got this error when I tried to parse an IP address that was in string form. I was using a public dns ip address (4.2.2.2) while testing this (using the System.Net's IPAddress.Parse method). It does the parsing correctly and returns an IPAddress object. However, if I try to access the ScopeId property of this object, a SocketException is thrown with the message given in the title. I really am not able to figure out whats the problem here. When I checked the documentation of IPAddress.ScopeId
