ip

问题 I want to find out the default network in use. My current method was to find all IP addresses and compare it to the default gateway IP address, but that sounds silly. What is the correct way of doing it ? UPDATE I want to use a C program, not by commands ... 回答1: You can try a slightly dirtier but infinitely easier approach: cnicutar@lemon:~$ ip route show to 0.0.0.0/0 default via X.Y.Z.T dev eth0 proto static ^^^^ So you can try: FILE *cmd = popen("ip route show", "r"); fgets(str, LEN, cmd);

问题 I'm using PHP and MySQL, and I want to store users' IP addresses into the database for comparison purposes (e.g. allowing only one flag to a thread per IP). Would it be okay to do it the following way? Retrieving it in PHP: $ipAddress = md5($_SERVER["REMOTE_ADDR"]); And then saving it into the database as a VARCHAR(32) . If I had to make a more comprehensive use of the IPs this wouldn't be the proper way to do it I guess, but if it's only to make sure that the same IP didn't do something

问题 I apologize for the broad question. But I have a list of IP addresses, and would like to connect them to the companies they came from. I'm not interested in identifying personal IP address information (probably not even possible) but I figure there must be a way to identify if the IP address is associated with a large corporation. Whois.net usually only gives the ISP name, not the company name. Thank you 回答1: The http://ipinfo.io API (my own service) returns the company name as the org field:

问题 -- I've searched to find out how to get my local ip address using python. (my python version is 3.4) And there is an answer. That answer says: import socket socket.gethostbyname(socket.gethostname()) And it works. script said my ip address is 192.168.56.1 . But my local (=internal) ip address is 192.168.0.100 . So, What was that ip address? It was an ip address of 'Virtualbox Host-Only Network' which was installed when I setup virtualbox a week ago. (Virtualbox's version is 5.0) I have now 2

问题 I am trying to create an app to find the exact location of IP address. I did some research on IP addresses and many more. But whenever I try to locate an IP address it provides the location of Internet Service Provider. I want to track the exact geolocation or long & lat of that place. So can anyone help me out to let me know how to find the geolocation of Dynamic IP address 回答1: The information upon which such a service might (hypothetically) be based is not available. Ergo, the ISP level

问题 This question is unlikely to help any future visitors; it is only relevant to a small geographic area, a specific moment in time, or an extraordinarily narrow situation that is not generally applicable to the worldwide audience of the internet. For help making this question more broadly applicable, visit the help center. Closed 8 years ago . Is it possible to run a code that searches IPConfig for the IP address then saves that to a text document or enters it into the prompt? I want to be able
