app that can record ip address

A public IP address is an IP address that can be accessed over the Internet. Private IP address on the other hand is used to assign computers within your private space without letting them directly expose to the Internet. For example, if you have multiple computers within your home you may want to use private IP addresses to address each computer within your home. In this scenario, your router get the public IP address, and each of the computers, tablets and smartphones connected to your router (via wired or wifi) get a private IP address from your router via DHCP protocol.

There are few ways to find out private ip address assigned to your computer network adapter and public ip address assigned to your router. In this tutorial i will explain easiest way to find out both private and public ip addresses assigned to your computer and router.

Finding IP address

Hello,

Thank you for writing to Microsoft Community Forums.

I suggest you to follow the steps mentioned below to find printer’s IP address:

1. Type Devices and Printers in the Windows search bar.
   
2. Select on the printer and click on
   Manage.
   
3. Click on the Ports tab.
   You will be able to find printer’s IP address under the ‘Ports’ tab.
   

Few printers also have a “Test print” option on the printer. When you print a test page from network printer, the page shows the IP address along with other details.

Note: If it is set on DHCP mode the IP address will constantly change.
The IP address is assigned automatically by your router using a protocol called DHCP.

Hope it helps.

Using Multiple IP Addresses in a Domain Network

I added an alternate IP address on the same network adapter and used this script to tell the alternate IP address that it is not the primary.

PS C:\WINDOWS\system32> Set-NetIPAddress 30.30.30.1 -SkipAsSource $true

PS C:\WINDOWS\system32> ping 30.30.30.1

Pinging 30.30.30.1 with 32 bytes of data:

Reply from 30.30.30.1: bytes=32 time<1ms TTL=128

Reply from 30.30.30.1: bytes=32 time<1ms TTL=128

Reply from 30.30.30.1: bytes=32 time<1ms TTL=128

Reply from 30.30.30.1: bytes=32 time<1ms TTL=128

This solution works fine on the same network adapter as it has the working and routable IP address.

This script will not work on a separate NIC; if it's added to the separate NIC, then the IP is disabled and has no routable address (General Failure), so I understand the fault now.

On my separate networks (network adapter A and network adapter B) I will add
mydomain.local to network adapter A's DNS suffix for this connection.
