There are times when an IT admin has to set up multiple IP addresses to the same network adapter. Setting up multiple IP addresses in scenarios like hosting various SSL sites, speed up traffic exchanges can help in avoiding being blacklisted in the SPAM filters, and so on. So in this post, you will be guided on how exactly you can assign multiple IP addresses to the network adapter in your Windows 10 computer. There are several ways to assign multiple IP addresses in a network adapter. You can do it using the Network Adapter settings or using the Netsh utility, as well as the Windows PowerShell utility. To get started, refer to each one of the options provided below.

Option 1 – Assign multiple IP addresses via Network Adapter settings

• Go to Settings first and from there, select Network & Internet, and then click on the Change adapter options. This will show you a list of both the physical and virtual network adapters in your computer.
• Next, double click on the Ethernet adapter where you want to assign the multiple IP addresses and then click on the Properties button.
• After that, you should see the Ethernet properties where you have to select the “TCP/IPv4” or “TCP/IPv6”.
• Once done, click on the Properties button and then select the “Use the following IP address” option under the General tab.
• Now you have to add an IP address, subnet, and default gateway to the network adapter and then click on the Advanced button.
• This will open the Advanced TCP/IP settings where you have to click on the Add button so you can add an IP address. From here, you can keep adding multiple IP addresses to the network adapter. You also have the option to add multiple gateways or DNS IP addresses.
• Once done, if you execute the “ipconfig” command, you should see all the secondary IP addresses listed.

Option 2 – Assign multiple IP addresses using the Netsh command

Another way to assign multiple IP addresses to your network adapter is via the Netsh command.

• In the Start Search, type “command prompt” and from the search results that appear, right-click on Command Prompt and then select the “Run as administrator” to open it with admin privileges.
• If a User Account Control or UAC prompt pops up, just click on Yes.
• After that, run this command: Netsh int ipv4 add address name="Local Area Connection" 192.168.100.100 255.255.255.0 SkipAsSource=True

Note: You have the option to set “SkepAsSource” since it depends on your needs using the Netsh command. When it is configured as true, the IP address won’t be used by the OS for outbound connections.

Option 3 – Assign multiple IP addresses via Windows PowerShell

• Tap the Win + X key combination and click on the “Windows PowerShell (Admin)” option.
• After opening Windows PowerShell as admin, use the NetIPAddress command so you can add more IP addresses. Execute this command: Get-NetIPAddress | ft IPAddress, InterfaceAlias, SkipAsSource
• Next, assign an IP address to a network adapter by executing this command: New-NetIPAddress –IPAddress 192.168.100.100 –PrefixLength 24 –InterfaceAlias “vEthernet” –SkipAsSource $True
• Now to modify the “SkipAsSource” parameter, use this command: Get-NetIPAddress 192.168.100.100 | Set-NetIPAddress -SkipAsSource $False

High Efficiency Image File Format (HEIF) is a container format for individual images and image sequences. The standard covers multimedia files that can also include other media streams, such as timed text, audio, and video. A HEIF image using High-Efficiency Video Coding, HEVC, requires only about half the storage space as the equivalent quality JPEG. HEIF also supports animation and is capable of storing more information than an animated GIF or APNG at a small fraction of the size. HEIF files are a special case of the ISO Base Media File Format (ISOBMFF, ISO/IEC 14496-12), first defined in 2001 as a shared part of MP4 and JPEG 2000. Introduced in 2015, it was developed by the Moving Picture Experts Group (MPEG) and is defined as Part 12 within the MPEG-H media suite (ISO/IEC 23008-12). HEIF was adopted by Apple in 2017 with the introduction of iOS 11, and support on other platforms is growing.

HEIF files can store the following types of data:

Image items

Storage of individual images, image properties, and thumbnails.

Image derivations

Derived images enable non-destructive image editing and are created on the fly by the rendering software using editing instructions stored separately in the HEIF file. These instructions (rectangular cropping, rotation by one, two or three quarter-turns, timed graphic overlays, etc.) and images are stored separately in the HEIF file, and describe specific transformations to be applied to the input images. The storage overhead of derived images is small.

Image sequences

Storage of multiple time-related and/or temporally predicted images (like a burst-photo shot or cinemagraph animation), their properties, and thumbnails. Different prediction options can be used in order to exploit the temporal and spatial similarities between the images. Hence, file sizes can be drastically reduced when many images are stored in the same HEIF file.

Auxiliary image items

Storage of image data, such as an alpha plane or a depth map, which complements another image item. These data are not displayed as such but used in various forms to complement another image item.

Image metadata

Storage of EXIF, XMP and similar metadata which accompany the images stored in the HEIF file.

As you know, storage devices are an important part of the computer system for porting, saving, and extracting data files. And for you to differentiate between storage devices on your computer system, each one of the storage devices is labeled with a unique number referred to as Disk Signature for identification. The unique disk identifier is stored as a part of the MBR or Master Boot Record. Disk signature is used by operating systems in order to identify and set apart different data storage devices and hard disk drives in the computer for data access. These days, Disk cloning has become a regular practice in upgrading to larger hard disk drives. Drives are cloned in order to produce a similar copy to use both the original drive and cloned copy together. Moreover, lots of virtualization tools are being used to virtualize the physical hard disk drives to create virtual hard disk drives and several virtual machine clones that are created with the existing virtual hard disk drives. And since these are identical copies, chances these copies may have identical disk signatures. As a result, when you use both disks that have identical signatures at the same time you run into the Disk Signature Collision problem. This kind of problem does not often occur as the Windows system does not really allow two disks to function simultaneously when they have the same disk signature. When you encounter a Disk Collision problem in your Windows 10 computer, you may see the following error messages:

• The boot selection failed because a required device is inaccessible
• The disk is offline because it has a signature collision
• This disk is offline because it has a signature collision with another disk that is online

You can fix the disk collision problem by changing the disk signature which you can achieve using the command line utility diskpart in Windows PowerShell or Command Prompt or using Windows Disk Management utility. To fix the disk collision problem, you can make use of the command-line utility called diskpart in Windows PowerShell or Command Prompt to view and change the signature, or can make use of Master Boot record in the Windows Registry. You can also make use of Windows Disk Management Utility to change the signature. Simply follow the given options below to change the disk signature either way.

Option 1 – Change Disk Signature via Diskpart

• Type “command prompt” in the Windows Search bar and then right-click on the related search result and select the “Run as administrator” option.
• After that, type the “diskpart” command and hit Enter to open Diskpart.
• Next, type the “list disk” command to display all the disks available in the system.
• Next, take note of the problematic disk number with the status Offline from the list and then type the “Select disk x” command where x is the offline disk to select the offline disk. For instance, if you type “select disk 1”, it will display the “Disk 1 is now the selected disk” message.
• Now type the “Uniqueid disk” command to display the disk signature and to change the disk’s signature and set the disk online, type the “unique disk ID= (New signature)” where (New signature) is the new ID in hexadecimal. For instance, you can set the new id as “unique disk ID= 1456ACBD”.

Note: If you have given the wrong format ID, the command prompt will display the following error:

“The specified identifier is not in the correct format. Type the identifier in the correct format: in hexadecimal form for an MBR disk or as a GUID for a GPT disk.”

• After you’re done, the disk will be online, and then restart your computer.

Option 2 – Change Disk Signature via Disk Management Utility

• Tap the Win + R keys to open the Run dialog box and then type “diskmgmt.msc” and hit Enter or click OK to open Disk Management.
• Next, right-click on the disk that is marked as Missing or Offline.
• After that, select the Online command from the drop-down menu.
• Then from the selecting option Online, Windows will generate a new disk signature.
