Archer C7 Looking up DHCP results via DNS

Model :

Hardware Version :

Firmware Version :

ISP :

My router's on 192.168.7.1, and has DHCP enabled, with 192.168.7.1 as the DNS server.

If I log into the router and look at DHCP client list, I can see that for instance watson has been assigned 192.168.7.100

However if I use nslookup to look up either watson or 192.168.7.100 it fails with "non-existent domain"

Am I doing something wrong, or is there no way for the router's DNS server to return information on the DHCP-assigned ips?

thanks

I think the DNS should be an external IP address shouldn't it ? , not your Router.... eg from your ISP or Google's Public ones eg 0.0.0.0 or 8.8.8.8

The router's DNS is set to 8.8.8.8.

But the DNS address all the dhcp clients are told to use is the router's address, because I assumed that the router's DNS server would check its DHCP client list first, and if it couldn't find a result, forward the request on to 8.8.8.8.

However all that seems to happen is that the router ignores the list of DHCP clients goes straight on to asking 8.8.8.8
