Hi Maik,
Thanks for the hint.
The thing is that my FB has native IPv6 connectivity, i.e. it receives a
prefix from the provider (which changes now and then, e.g. after
disconnect).
So IMHO there is no need to assign ULA addresses via DHCP. The clients
already configure themselves correctly via SLAAC.
According to the dnsmasq manpage:
If a dhcp-range is only being used for stateless DHCP and/or SLAAC, then
the address can be simply ::
--dhcp-range=::,constructor:eth0
That's what I've used. So AFAIU the clients now configure themselves and
only ask dnsmasq (via DHCPv6) for information about the DNSv6 server.
However, I don't know if dnsmasq will add to its DNS the hostnames of
clients requesting DNS information via DHCP only (and not getting
assigned any address).
By the way: What did you set in the IPv6 address settings of your FB
("Heimnetzübersicht" -> "Netzwerkeinstellungen" -> "IPv6-Adressen")?
Best regards,
Robert

Hi Robert,
I use this parameter for IPv6 with a FB:
enable-ra
ra-param=high,60,7200
dhcp-range=fd00:cafe:beef:1:0050::,fd00:cafe:beef:1:F000::,64,2h

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 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::
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 records for local
hostnames.
Is this configuration basically correct? Or am I missing something?
Best regards,
Robert
