Ip addresses connected to wifi

How to get all IP address of systems connected to same Wi-Fi network in android

Can someone tell me how to find the IP addrss of all the systems connected to same network in Android programatically. DHCPInfo class gives only the ipaddress assigned to our android device but not for the other devices connected to the same network. How to get ipaddress of other devices connected to same network?

I do not think a DHCP server is going to provide this information to one of its (connected) clients independent of the platform (Android in this case) of the client.

Since the IP V4 address range is pretty much used up by now, simply assume that every valid non-local IP V4 address is used by a device on the same network, namely the Internet. You’ll be able to live with the few exceptions. — Sorry, couldn’t resist. You’re the n-th person asking this during the last few days. Of course, this is impossible in general.

@RajeshCP Unlike the post you refer to, this question here is Android related, and the OP did not indicate that the devices run a particular app. Besides, the question is whether or not you have a cooperative infrastructure. In many places, the router of «the network» will disallow communication between network clients.

First get the host ip by this

public String s_dns1 ; public String s_dns2; public String s_gateway; public String s_ipAddress; public String s_leaseDuration; public String s_netmask; public String s_serverAddress; TextView info; DhcpInfo d; WifiManager wifii; wifii = (WifiManager) getSystemService(Context.WIFI_SERVICE); d = wifii.getDhcpInfo(); s_dns1 = "DNS 1: " + String.valueOf(d.dns1); s_dns2 = "DNS 2: " + String.valueOf(d.dns2); s_gateway = "Default Gateway: " + String.valueOf(d.gateway); s_ipAddress = "IP Address: " + String.valueOf(d.ipAddress); s_leaseDuration = "Lease Time: " + String.valueOf(d.leaseDuration); s_netmask = "Subnet Mask: " + String.valueOf(d.netmask); s_serverAddress = "Server IP: " + String.valueOf(d.serverAddress); 

Now get connected ips by this

String connections = ""; InetAddress host; try < host = InetAddress.getByName(intToIp(d.dns1)); byte[] ip = host.getAddress(); for(int i = 1; i else if(!address.getHostAddress().equals(address.getHostName())) < System.out.println(address + " machine is known in a DNS lookup"); >> > catch(UnknownHostException e1) < e1.printStackTrace(); >catch(IOException e) < e.printStackTrace(); >System.out.println(connections); 

public String intToIp(int i) < return (i & 0xFF) + "." + ((i >> 8 ) & 0xFF) + "." + ((i >> 16) & 0xFF) + "." + ((i >> 24) & 0xFF); >

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.
