nslookup returns the original device name

[mikicho]

I set up names for my devices in the "Network Map", but when I do nslookup 192.168.50.136 192.168.50.1 I get the real device name.
How do I instruct my Asus router to display the device names that I have configured?
Model: RT-AX58U
Firmware version: 3.0.0.4.388_24762

names for my devices in the "Network Map"

These names are not related to DNS records.

when I do nslookup 192.168.50.136 192.168.50.1 I get the real device name

This is normal
NSLOOKUP does not output the real name
NSLOOKUP does not output the name from the ASUS Network map
NSLOOKUP outputs an A-type DNS record in local DNS registry (on router)

The A-type record is made by the local computer (if it wants to) in order to register itself in local DNS registry

But yes, the name for DNS registration is the real name of the computer

To change the name in the DNS registry, you need to rename the computer

Thanks for the detailed answer!
I want to manage all the device names in the router instead of changing them on each device.
Is ASUS able to do this as a DHCP server?

If you make IP reservations in DHCP server you can add host names.

Oh, so I have to set the IP manually for the router (DHCP server) to publish the custom client name I put in the Network map?

 

[Tech9]

Client name in Network Map is unrelated. You can have Desktop PC1 as client name with dpc1 as host name. You can change the client name after, the host name will remain the same to whatever was set in DHCP server.

Oh I see..
This process is a bit cumbersome because I have to manually set the IP and enter the name twice. However, it's not a major issue.
Thanks!

I guess, you don’t need to call by host name all the clients on your network.
