Dnsmasq local hostnames with IPv6

[Nazar78]

Hi all,

I have the RT-AX86U 386.3_2, recently configured with IPv6 Tunnel 6rd, DHCP and RA enabled but I have issues resolving IPv6 in clients hostnames.

Strange is querying the router's hostname does return IPv6 but not the rest of the clients hostnames:

C:\Users\nazar>nslookup RT-AX86U
Server: RT-AX86U.RT-AX86U
Address: 192.168.1.1

Name: RT-AX86U.RT-AX86U
Addresses: 2400:d803:XXXX:XXXX::1
192.168.1.1

C:\Users\nazar>nslookup MEG-Trident-X10
Server: RT-AX86U.RT-AX86U
Address: 192.168.1.1

Name: MEG-Trident-X10.RT-AX86U
Address: 192.168.1.3

Below is my default dnsmasq.conf, I've tried changing the dhcp-range from ra-stateless to ra-names then restarting the daemon:

pid-file=/var/run/dnsmasq.pid

How can I have IPv6 returned in the local clients queries without putting static names in the host file or using address=/foo/bar? Appreciate any advice, thank you.

here is an example line for use in dnsmasq.postconf

pc_replace "dhcp-range=lan,::,constructor:br0,ra-stateless,64,600" "dhcp-range=lan,::2,::500,constructor:br0,slaac,ra-names,64,600" $CONFIG

Thank you very much! After setting this I can start to see the IPv6 in the lookups. I was looking for a solution for quite some time before posting. Thank you again.

Glad it worked.
