What is obtaining ip address in wifi

Can I get the IP address of the access point to I am connected to over wifi?

Hi I am new to android programming. I am basically trying to connect to an access point and send it come commands. After connecting to it over wifi, is it possible to programatically obtain it’s IP address so that I can establish a http connection with it? So far I know that we can obtain the device IP, but not sure if the access point IP can be obtained. Please help. Thanks in advance.

@kabuko The access point I am referring to does have an IP address assigned. I can ping and connect to it. My question was if it was possible to obtain this IP from an android application. Also, the duplicate post does not answer this question.

public static String getApIpAddr(Context context) < WifiManager wifiManager = (WifiManager) context.getSystemService(Context.WIFI_SERVICE); DhcpInfo dhcpInfo = wifiManager.getDhcpInfo(); byte[] ipAddress = convert2Bytes(dhcpInfo.serverAddress); try < String apIpAddr = InetAddress.getByAddress(ipAddress).getHostAddress(); return apIpAddr; >catch (UnknownHostException e) < e.printStackTrace(); >return null; > private static byte[] convert2Bytes(int hostAddress) < byte[] addressBytes = < (byte)(0xff & hostAddress), (byte)(0xff & (hostAddress >> 8)), (byte)(0xff & (hostAddress >> 16)), (byte)(0xff & (hostAddress >> 24)) >; return addressBytes; > 

I assume you mean the outside (public) IP address of the access point that the device is connected to. If so, yes there is a simple way to get the public IP address of the access point that a device is connected to. Simply setup a script on a web server that will echo back the IP address of any client that connects to it (similar to www.whatismyip.com). Then, your device just needs to do a GET request to the script, and this will return the outside IP of the access point that the device is connected to.

thanks, but unfortunately, I will not have access to any other web server. This needs to be a standalone android app that interacts just with the access point it is connected to. Also, by IP of access point, I meant the IP that is assigned to it by a DHCP agent using which the AP can be pinged.

I am using this to get the IP address

try < for (Enumerationen = NetworkInterface.getNetworkInterfaces(); en.hasMoreElements();) < NetworkInterface intf = en.nextElement(); for (EnumerationenumIpAddr = intf.getInetAddresses();enumIpAddr.hasMoreElements();) < InetAddress inetAddress = enumIpAddr.nextElement(); if (!inetAddress.isLoopbackAddress()) < //My IP address String Ip= inetAddress.getHostAddress().toString(); >> > > catch (SocketException e)

Thanks Gaurav. The above code returns an ipv6 address when connected to wifi. So I am not able to check if this is the right address. I also tried including if (!inetAddress.isLoopbackAddress() && (inetAddress instanceof Inet4Address)), but again I don’t get any IPv4 address. The AP i am connected to does have an IPv4 address, and I can ping it from within the subnet. But this is not returning the same.

How to Find IP Address of WiFi

The internet is full of endless possibilities, and each opportunity is put into reality using the Internet Protocol (IP) addresses. This address uniquely identifies your computer amongst others online.

Since you hardly ever come across a situation where you need to find your router IP address, you’ll probably find it tricky when this does happen. However, this is a simple process, and you can perform it on various devices connected to the router.

An IP address is a unique string of numbers. All devices, including mobile phones, laptops, and cell phones, will have an IP address. The Internet needs this address so it can identify each device individually.

We’ll cover how you can find your IP address, but first, let’s discuss why you may need to do this in the first place.

Why Would You Need to Find the IP Address of Your WiFi?

IP addresses allow you to troubleshoot network problems, check router settings, and even configure the software. For example, if you wish to switch your network name or set up a new network, you will need to find your WiFi IP address. This can also help in identifying intruders.

What is a Router?

A router is a hardware device that physically connects your modem to the internet via a WAN port or cable. These tiny devices contain a CPU and memory to help you set up an internet connection. If you have access to Wi-Fi, you have already dealt with a router.

What exactly is the IP Address of a WiFi Router?

There is often confusion when it comes to the difference between your router IP and your default gateway. So let us unlock these terms for a better understanding of how to find your IP.

Router IP Address

The Router IP is an identification number for whatever device is in touch with your network. This helps the device to send and receive data in the form of packets. Every action using the internet, from browsing blog articles to watching your favorite show, involves these packets.

Default Gateway

A gateway is a node in your network which allows an inter-network connection. When your network connects to other networks, the default gateway is the IP address of the interface of your router.

What are the different types of IP Addresses?

1. Public: Internet Service Provider (ISP) assigns public IP addresses to you.
2. Private: Allows connection between all devices that you own.
3. Static: Does not change over time.
4. Dynamic: Changes over time.

Private IP addresses connect with public ones to access the world wide web. Your router uses a static public IP address from your modem and transforms it into a dynamic private IP address, which eases the task of connecting new devices to your network.

What does my IP Address Show?

Your IP address offers rough information about your geographical location. This often concerns people, but you do not need to worry about this. Since IP addresses involve a network connection, only a rough spot is indicated.

The information revolves around your ISP’s location and not your house number. Devices share Public IP addresses, so they do not direct only to you. If you’re still worried, you can always use VPN (Virtual Private Network) to secure your connection and hide your router’s IP address.

There are several VPN applications around, some of the most common being AvastSecureLine VPN and Nord VPN. They help in protecting you by making sure your internet traffic moves on a hidden path.

This path is not visible to everyone. It routes your connection through a different IP address located somewhere very far away from you. Even your VPN and internet providers will not be able to access your information and location.

What is the format of my IP Address?

Every IP address is broken into two parts – one identifies the computer connection, while the other determines the network. Therefore, your router’s IP address can be in groups of numbers four or eight, depending on the IP version.

Wifi network client and IP address, how to discover them, without monitor mode

Discovering the wifi client ip is very easy and very simple.

Even if you don’t have a card in monitor mode you can always know the wifi client ip of connected clients that your access point or wifi network has. In recent times communications and especially in homes are done wirelessly, despite this there are still a lot of devices that we have wired to the network. This large number of connected devices makes it difficult to control and track which ones are or are not connected, consuming WiFi or should not be connected.

How can we see the wifi client ip and other network devices?

Being connected by WiFi to your router or AP, you will be able to see the computers connected to the network, as well as telephones, IoT devices, etc. Acrylic Wi-Fi Analyzer is able to perform a network scan for devices With this you can not only determine how many devices and which are connected but thanks to the inventory in an immediate way identify new devices. In an easy and simple way you will be able to find out if someone is stealing your WiFi, or if there are unknown devices in the WiFi network. If you have a house connected with home automation or many IoT devices it is especially useful to see if all your devices are connected and working properly because with the inventory you can easily identify them. If you don’t know which device it belongs to in the wifi client ip list, you can look at the value of the manufacturer’s field, which usually helps a lot in case of doubt.

Why it is interesting to know the wifi client ip and devices of your wifi network.

The more information we can get from our WiFi network, the easier it will be for us to determine if there are any performance or security issues. This is especially interesting for determining if any of your children are connected to the internet when they shouldn’t, without being a parental control. Also just simply keeping track of what devices are or shouldn’t be connected. Periodically, Acrylic Wi-Fi Analyzer does a network scan for devices. This search is transparent to the rest of the network users and nothing intrusive. You will not be affected by the performance of your connection, and you will gain knowledge of your network. These network scans are made over the WiFi network you are connected to. Sso you don’t expect to see without the monitor mode, clients of other WiFi networks that are not yours.

Recommendations and good practices

• It is recommended to periodically analyze the network to see that it is in the same state in which we left it.
• It is a good practice to inventory all the devices in our network.
  • so that at any time we can identify any new device and analyze if it is a legitimate connection
  • If otherwise we have to further investigate what makes that device connected.
