IPV6 and DHCP

Hi All,

One of the things that has pushed back the deployment of IPV6 on my network is the lack of DHCP server for V6 addresses from Novell. I know IPV6 does not technically need DHCP but I would like to use it as a central distribution of name server info, slp services etc. but it does not seem like it supports it.

Am I missing something? If not anyone know if it will support it in the future, if so when?

Thanks

I have heard that there is another dynamic mechanism for assigning the kinds of stuff you would normally hand out for dhcp, but unfortunately, I haven't been able to find anything on that "mechanism"

Re: IPV6 and DHCP

I investigated this a few years back and did not find anything, just got done with a MS class and looks like MS is not supporting DHCP IPV6 now so I was hoping that Novell was also, but it looks like it is lagging behind on this one.:(

Opps, meant MS is supporting IPv6 now with their DHCP server. Sorry about that. Maybe this will put a little fire under Novell to get it going.

All I am aware of is that under SLES 11 there is a separate rpm for IPv6, but I am not sure whether it fully supports IPv6 yes. There isn't any support for IPv6 management. I don't believe on OES (and NetWare for that matter) you will currently find it.

My guess is that if you do start to see it it will be with the next round of OES, but that is just a guess.

Re: IPV6 and DHCP

Did get a answer from Novell. It is not supported. According to the tech it is not something a lot of people ask for and suggested I put an enhancement request in, which I did. Also need to send an email to my Sales guy so he can push for it to be put in.

That's also what I'm seeing in my customer base. There is interest, but not to implement as there are considerations and unknowns to how each infrastructure will handle mixed IP4 IP6 networks.
Mostly, as the private networks within companies I work with suffice for plenty addressing and subsets in the IP4 networks they have setup - and although an ugly hack, NAT does the rest, 'we' are waiting for 'the internet' to lead the way, as that is where the pain mostly lays.

Not that this really adds to the thread, but I do see where the low request volume for DHCPv6 (OES integrated) stems from.

Cheers,
Willem

Out of curiosity, for the OP, what is the desired functionality provided
by DHCPv6 that you're after? Most admins want a way to give out IP
addresses, though in IPv6 the control of those (at least handing themout)
isn't that critical since the counts are insane. Neighbor Discovery
Protocol (NDP) seems to be able to take care of the allocation of required
basic network information but there could be other things I suppose.

Good luck.

Re: IPV6 and DHCP

It is mostly for the distribution of options, such as SLP, DNS and other settings. The idea of allocating defined IP's is nice as well but it is mostly the distro of options in a routed network. I am the first to admit I am not an expert in IPV6 but there seems to be the assumption that IPV6 automatically gets rid of the need to route, vlan's and other IP V4 techniques. For me I do not just use subnets/routers to limit collision domains but to also filter packets, apply QOS and to keep sensitive information separate from non-sensitive information.

From what I have seen of most routing switches there are not a whole lot ability to apply options on the routed interface besides, I do not really want to go to every route point to change a DNS option or other option I want to push out, that is where a DHCP V6 server would be great.

If there is some other option in V6 that does this that I am just ignorant of I would like to hear it, as I said I am no IPV6 expert but I have read a couple of books on it and they really just brush over the ability to grab options from the network but do not really specify how or what software can do it, only that it is possible in the protocol.

Hope that explains it.
