ip-address interview questions
Top ip-address frequently asked interview questions
I have a script that is to be run by a person that logs in to the server with SSH.
Is there a way to find out automatically what IP address the user is connecting from?
Of course, I could ask the user (it is a tool for programmers, so no problem with that), but it would be cooler if I just found out.

What is the most efficient way to store and retrieve IP addresses in MySQL? Right now I'm doing:
SELECT * FROM logins WHERE ip = '1.2.3.4'
Where ip is a VARCHAR(15) field.
Is there a better way to do this?

If you need to locate a user based on their IP address, what services are available (free and not free services are fine)?
P.S. I understand that some users use proxies etc., that means the result is not 100% accurate. That's ok.

I know regex is dangerous for validating IP addresses because of the different forms an IP address can take.
I've seen similar questions for C and C++, and those were resolved with a function that doesn't exist in C# inet_ntop()
The .NET solutions I've found only handle the standard "ddd.ddd.ddd.ddd" form. Any suggestions?

I understand it's a standard practice to look at both these variables. Of course they can easily be spoofed. I'm curious how often can you expect these values (especially the HTTP_X_FORWARDED_FOR) to contain genuine information and not just be scrambled or have their values stripped away?
Anyone with the experience or statistics on this stuff?
Is there anything else that can be useful for the task of getting the client's IP address?

What should be the most recommended datatype for storing an IPv4 address in SQL server?
Or maybe someone has already created a user SQL data-type (.Net assembly) for it?
I don't need sorting.

I'm not too sure how to go about getting the external IP address of the machine as a computer outside of a network would see it.
My following IPAddress class only gets the local IP address of the machine.
public class IPAddress {
private InetAddress thisIp;
private String thisIpAddress;
private void setIpAdd() {
try {
InetAddress thisIp = InetAddress.getLocalHost();
thisIpAddress = thisIp.getHostAddress().toString();
} catch (Exception e) {
}
}
protected String getIpAddress() {
setIpAdd();
return thisIpAddress;
}
}
