Re: [Dnsmasq-discuss] DHCP mangling IP address, host name
Hello, > I'm getting a confusing result with my DHCP server part. > dhcp-host=00:25:f6:03:2a:5d,iris,192.168.0.10/24 Probably hostname and ipaddr needs to be exchanged.

Is a multi homed machine not a usefull scenario in IPv6? This would avoid unnecessary routing (as in IPv4).

[Dnsmasq-discuss] localise-queries and IPv6
Hello, I've added entries for a multi homed machine to the hosts file. For IPv4 i get one address localized to the caller, for IPv6 i get a list of all addresses. The man page notes for localise-queries 'Currently this facility is limited to IPv4.' Is there any technical reason for this behaviour or is there just 'a bit work to be done'?

It's like the NATed private IPv4 addresses i use locally. The delegated prefix is only for outside connections.

Re: [Dnsmasq-discuss] define IPv6 prefix for host-records
Hello Simon, > How do your machines get their IPv6 addresses, and specifically, their > changed IPv6 addresses after the prefix changes.? With RA/SLAAC, i have a dibbler client running receiving the prefix via DHCPv6 and distributing it via RA. Can dnsmasq be configured to run as DHCPv6 client too? > If you're using DHCPv6 with dnsmasq as the server, At the moment not, i'm using dnsmasq vor DHCPv4 and DNS I have no DHCPv6 server running (neither dnsmasq or dibbler or something else) > then something like this is already available: if you have a dhcp-range line > which > has the constructor: keyword, then you can have IPv6 addresses in > dhcp-host lines which have zero network part, and the relevant prefix > will be substituted in. I've seen this which pointed me to the proposed syntax.

[Dnsmasq-discuss] define IPv6 prefix for host-records
Hello , i'm using dnsmasq to deliver IPv6 DNS entries. The IPv6 prefix i get dynamicaly from my ISP after dialin (pppoe), but this changes on every reconnect (which is at least once a day). When the prefix changes every IPv6 host in /etc/hosts dnsmasq.conf files has to be changed to cause dnsmasq to deliver the IPv6 address containing the new prefix. (I didn't find a posibility to configure dnsmasq to do this automatically) I would like to suggest to add an "constructor:" option to --host-record like: --host-record=[,],[],[][,constructor:][,] Where [] contains only the host-/local-network part and [constructor:] will add the prefix from e.g. --host-record=myhost,10.1.2.3,::0123:4567:89ab:cdef,constructor:eth1 for adding the /64 prefix of eth1 Regards Carsten pgpyqUwxzxzcl.pgp Description: Digitale Signatur von OpenPGP ___ Dnsmasq-discuss mailing list Dnsmasq-discuss@lists.thekelleys.org.uk http://lists.thekelleys.org.uk/mailman/listinfo/dnsmasq-discuss
