[Dnsmasq-discuss] IPv6 host registration in DNS

[Robert N]

Hello all,

I'm trying to replace the DNS/DHCP of my FritzBox home router with 
dnsmasq.

For IPv4 everything seems to work fine, i.e. when clients request an 
IPv4 address, dnsmasq registers their hostnames, so name resolution for 
local machines works.

But it does not seem to work for IPv6. I want the clients to do SLAAC 
but still dnsmasq should serve AAAA records for local hosts if asked 
for.
If I understood correctly, then dnsmasq will only register the hostnames 
for which it receives a DHCP request. Does this require the hosts to 
request an IP address? Or will the hostnames be added to DNS also if 
just the DNS server information is requested?

So I probably should configure what is called stateless DHCPv6:

------------------------------------
no-resolv
server=8.8.8.8
server=8.8.4.4
server=2001:4860:4860::8888
server=2001:4860:4860::8844

domain=home.example.net
local=/home.example.net/
domain-needed
bogus-priv
expand-hosts
stop-dns-rebind

enable-ra
ra-param=high

read-ethers
dhcp-option=option6:dns-server,[fd00::]
dhcp-option=option6:domain-search,home.example.net
dhcp-range=::,constructor:lan,ra-names,ra-stateless

# This will tell DHCP clients to not ask for proxy information
# Some clients, like Windows 7, will constantly ask if not told NO
# 
https://wiki.openwrt.org/doc/howto/dhcp.dnsmasq#log_continuously_filled_with_dhcpinformdhcpack
dhcp-option=252,"\n"

log-async=10
log-dhcp
------------------------------------

However, I don't get dnsmasq to return AAAA records for local hostnames.
Is this configuration basically correct? Or am I missing something?


Best regards,
Robert
