IPv6 Support in DNS service

Hi,


I have setup DNS (server) Service in the Lion Server and have populated all the necessary zones as well as DNS records for IPv4 ip addresses to the devices within the local infra. However, when I tried to create DNS records for IPv6 ip addresses, it will prompt the error "xxxx:xxxx:xxxx::xxx" is not a valid IPv4 address".


Does this means that the DNS (server) Service in Lion Server does not support IPv6?


Is Lion Server fully ready for IPv6?

Additional Info:


Just in case some forumer is puzzled over the fuzz about IPv6 (saw in another thread), here is some additional information to quench the curiousity thirst.


In the location where I reside in, there is a large national initiative pushing out FTTH national-wide. And concurrently, there is another not-as-large initiative pushing out IPv6 but with focus mainly on business connections (incentives provided to switch over to IPv6 offerings). However, there are some RSPs of the FTTH initiative that included the IPv6 offering when rolling out FTTH connections (both business and even for residentials).


Thus, IPv6 is slowly increasing momentum to replace IPv4 as a national-wide standard for business connectivity and will cascade to residential connectivity though may take another half-decade or decade to fully switch.


In summary, the FTTH connection I have, offers IPv6 and I am just planning ahead while in the mist of full revamp/swing of local infrastructure towards Apple's Mac OS & iOS platforms. Thus, it doesn't make sense that the fiber internet connection I am using has a public IPv6 address and yet the internal infrastructure cannot fully support IPv6.

Mac OS X server uses the open-source BIND software as its DNS server. Unfortunately the Server.app and Server Admin utilities for configuring this do not provide a means to configure IPv6 records. As the underlying BIND software does support this it would in theory be possible for you to do this manually by editing the BIND configuration files.


My suggestion therefore would be to research how to configure standard BIND software for IPv6, you are probably best looking at Linux based examples.


On a different topic, Apple's DHCP server is a heavily modified version of bootpd and does not support IPv6 at all. Apple's web-server is Apache and should support IPv6.

Mixed sentiments.


It's glad to hear that the underlying BIND (DNS Server) supports IPv6. However, having to manual configure via CLI means it will break the link with the GUI (Server.app & 'Server Admin' tool).


And without DHCP Server supporting IPv6, it just makes the infrastructure a half-baked one.


Guess I have to re-evaluate if Lion Server is indeed the right choice for the ongoing redesign of my infrastructure to upgrade and with slight future-proof.

I would tend to agree, I have previously sent Apple reports saying they need to fully support IPv6 in their server software (they already do fully support IPv6 for their client operating system).


You can install an open-source dhcp v6 software such as dhcp6s or ISC dhcp 4.1, also nothing prevents you running the dhcp server separately to the Mac server, so a suitable Cisco router would also do the job.
