I need to obtain client local IP address into internal network not the IP over internet by angular for some reason that data will send to IP address over network not based on authorization,I googled so much and I can just find the IP over internet,
Now how can I solve this issue? thanks
Client IP address cannot be accessible by you or with any NPM from front end.
U can find different IP's over internet don't use it.
If you want the client IP, can only be accessed in Node.js.
NPM - request-ip

For example i send a request to https://www.w3schools.com/ which is showed Remote Address: 192.229.179.87:443 on Inspect tools, can i get that ip in js?
An IP address or Internet Protocol is used in hand with TCP(Transmission control protocol) to identify and share information between computers on the internet. Because it would be a very hard job for humans to keep IP's of various servers in the head, all IP addresses are saved on a DNS server together with their domain names. Hence, whenever you make a request to a site in your web browser, the web browser first visits a DNS server to fetch the IP address corresponding to your domain before making a direct request to the server. Hence there is no Javascript code or command to generate IP addresses from domain names. Hence to accomplish this, you'll have to use an API which will do all the hard work for you.
Check this question for some API's : API's for getting IP
I am using a IP location Service. which return location of the Ip. But When some proxy user login My site return wrong address Because the IP is Proxy. How to find out the user using proxy IP and find server Ip From Proxy IP in Javascript
.
While the point of a proxy, as Ryan says, is to block this, in some browsers it is possible to use RTCPeerConnection to get the user's IP.
This is not a perfect solution, and can be blocked fairly easily. Firefox has a built in setting to turn it off, in Chrome uBlock Origin can be used to block it. To check if your browser is vulnerable you can use this page, or take a look at the GitHub Repo.
Can you say how to website can can obtain real IP user with JavaScript, whereas people using a proxy, please?
Thanks
Client-side Javascript cannot, by itself, obtain your IP address. And, even if it did, what it would likely see is an internal network IP address, not a public IP address.
So, the only way to get the IP address from plain Javascript is to ask a server to tell you what your IP address is. You make an Ajax request to the server with a request that tells the server you want it to return what your IP address is. The server can then return the IP address that it sees your connection coming from. This address will be your outwards-facing public IP address. Since most client computers these days are behind some sort of router/firewall, what the server is probably seeing is a single public IP address that is being NATed from your actual client computer.
If there was a proxy server in the route between my client computer and the server, then the server would see the IP address of the proxy server, not the IP address of the client computer. And, there is nothing you can do to change that. Proxies and routers are specific designed to map one set of private IP addressing to a public IP addresses while keeping the network topology of the private network completely hidden from the outside world.
For example, the actual IP address of my local computer right now is 192.168.1.17 which is a local IP address on my home network. But, when I ask a server out on the internet what my IP address is using a service like http://whatismyipaddress.com/, then it reports the actual public IP address that Comcast has assigned to my router which is 67.180.86.xxx. When I make a connection to the internet from my local computer, that connection goes first to the router where the router uses NAT (network address translation) to map this connection between my private IP address on the home network and a particular outgoing TCP connection from my public IP address. When packets flow back on that connection, the router forwards those packets to my private IP address on the home network.
I know that it is possible. Tor broswer, block JavaScrip beacause they can obtain real public IP address of client. And I would know how to JavaScript can obtain ,the real public IP adress, whereas user use a proxy server.
How can I get the IP address (elastic IP) of the current Node.js host/server on Amazon EC2?
Calling req.connection.address() is useless because EC2 uses an elastic IP. In fact, the IP that shows up using the ifconfig command is not the same as the IP which was used to access the server from outside (which is what I need). How can I get the elastic IP automatically?
From within the instance, you can query for metadata about the instance by sending requests to http://169.254.169.254.
More information can be found here: http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/AESDG-chapter-instancedata.html
You can use DescribeInstances in the API as per the documentation using the filter ip-address to get the public IP of your instance.
Reading about headers and about elastic IP's, I would suggest that headers['REMOTE_ADDR'] gives the address you're looking for (unless behind a load balancer).
Can anybody let me know the logic they use to get the IP?
The server has to know your IP address to send you a response. That is how the internet works. Presumably they store the IP address for the last account activity in a database somewhere.
When your browser connects to their web site, their HTTP server determines the IP address from the connected socket. That IP address is supplied to Google's web application framework, which stores the IP address in some kind of data store, so that it can be retrieved later. I can't give you much more detail, since I don't work for Google (and even if I did, I probably wouldn'couldn't).
request.getRemoteHost();
this method in the request object will return the ip address of the client.
