Found the Device Name MSFT 5.0 on Your Router? Unraveling the Mystery

Understanding MSFT 5.0 and Its Implications

If you've noticed the unfamiliar device name "MSFT 5.0" on your router's DHCP client list, you might be wondering what it is and whether it could be related to your Synology NAS. Let's delve into the details and set your mind at ease.

DHCP Discover-Offer Process

When a device on your network needs an IP address, it initiates a DHCP Discover-Offer process. This involves sending a broadcast message to the DHCP server (typically your router) requesting an IP address. The router then responds with a DHCP Offer message, assigning an IP address to the device.

Client Vendor Name Update

Recently, some Windows-based devices have had their traditional Client Vendor Name updated. Instead of "MSFT 5.0," some devices now display as "MSFT 5.0." This is a change on Microsoft's side and doesn't indicate any security concerns or device malfunctions.

Troubleshooting Device Name Change

If you've noticed your PC's name has changed to "MSFT 5.0" unexpectedly, you can try booting your router. If this doesn't resolve the issue, you may need to contact your internet service provider (ISP) or router manufacturer for further assistance.

Conclusion

The device name "MSFT 5.0" appearing on your router's DHCP client list is not inherently related to your Synology NAS or any security breaches. It's simply a result of a recent update to the Client Vendor Name for Windows-based devices. If you encounter any device name issues, try rebooting your router or seek assistance from your ISP or router manufacturer.
