Names such as what you are seeing are often the result of a reverse DNS lookup using the IP address.

many times a home router will cache DNS names associated with an IP address. If the IP address is a DHCP assigned IP address, it is possible the local router has outdated cached information.

Hello, Bob.

I found the reason and how to fix it.

My current DHCP IP registered to DNS server.

And it can check NetBIOS name of WINS tab in WIFI setting window.

I fixed my hostname to NetBIOS after clearing the mapping list at DNS Server.

It is displayed by IP, now.

Thanks.
