ip-address

问题 According to Dotnet reference , Dns.GetHostAddresses("") should return IPv4 addresses . However I am getting only IPv6 on my windows 7 machine. I tried the program on a different windows 7 still the same result. It only returned IPv4 correctly on an XP machine. If I try , Dns.GetHostEntry(""); It now correctly returns one IPv4 and one IPv6 . How do I get IPv4 from GetHostAddresses() because I don't want to use GetHostEntry(). It looks up the DNS. Also, say for a computer with 1 Network card,

问题 The newsletter_ip field in MySQL is set as an UNSIGNED INT (10). I've also tried INET_ATON to format the data, but my results always look like this. Here is part of my processing code: //Retrieve data from user and create variables $ip_orig = $_SERVER['REMOTE_ADDR']; $ip = ip2long($ip_orig); //Place into database $sql = "INSERT INTO newsletter(newsletter_email, newsletter_ip, newsletter_date, newsletter_time) VALUES('".$email."', '".$ip."', '".$date."', '".$time."')"; I've also tried this

问题 I manage a web site that used to be hosted on Server A. I gave clients a subdomain url that pointed to this server, e.g. app1.example.com I have moved my web site to a new server, Server B. I changed the IP address of app1.example.com (via the domain name host company) to point to the new server and this worked ok, for me at least. However, I have one client that is still getting directed to the old server. When I get the client to ping app1.example.com it is trying to ping the old Server A.

问题 I've created a python project that scans an ip range (ie. x.y.z.0/24) and returns a list of online hosts. It saves the online hosts list to file with just the ip's (ie ['192.168.0.1', '192.168.0.2', '192.168.0.8',...]. I'm having trouble with this next step. I'd like to compare this online hosts list to an IP range to verify that these are computers to eliminate other devices. I have a DHCP Reservation List for computers that I can use. Is there a simple way to do this and update the onHosts

问题 After inputting the Rechability classes Apple provided. Also after inputting this, Reachability reachabilityWithAddress:(const struct sockaddr_in *)hostAddress. How should we input the IP address we want to check into this line? This is the part where i'm really lost at. 回答1: struct sockaddr_in is a low-level "socket address" type used by BSD sockets. We generally don't deal with them at the Cocoa level, but they can creep up from time to time, including in Apple's demo class. The reason

问题 I have the Maxmind Geolitecity database in a Mysql database. I could see field like startIpNum and endIpNum . The values for those fields are like this: 16777216 for startIpNum and 16777471 for endIpNum`. My ip is 115.184.126.186, how can I convert my ip to match the startIpNum or endIpNum ? 回答1: Either use inet_aton() as suggested by lmz, or do it in php using: http://php.net/manual/en/function.ip2long.php Note that this function returns an signed integer, meaning ranging from − 2,147,483

问题 I have a database table which contains an unsigned integer field to store the visitor's IP address: `user_ip` INT(10) UNSIGNED DEFAULT NULL, Here's the snippet of PHP code which tries to store the IP address: $ipaddr = $_SERVER['REMOTE_ADDR']; if ($stmt = mysqli_prepare($dbconn, 'INSERT INTO visitors(user_email, user_ip) VALUES (?,?)')) { $remote_ip = "INET_ATON('$ipaddr')"; mysqli_stmt_bind_param($stmt, 'ss', $email, $remote_ip); if (mysqli_stmt_execute($stmt) === FALSE) return FALSE; $rows
