Anycast usable DNS server

edited September 2012 in Help

I'm looking for a DNS server that:

*Can replicate to 3+ DNS servers
*Has IPv6 support and can bind to multiple v4 IPs
*Prefferably with Webinterface
*Must fit in sub 200MB RAM because i need around 50MB for my BGP setup

All 3 servers must hold the same zone and it cannot have problems to bind to the same IPs on ALL servers + 1 additional dedicated IP for the sync (I set up BGP on the VPS and announce a /24 + /48 v6, it should bind to 2 IPv4 of them and 2 IPv6 IPs + the normal dedicated IPv4 of the VPS for syncing, IPv6 does not matter for the sync)
It also must continue to run and sync when 1 or 2 of the other DNS go down (sync only to the DNS that are still left of course)
One VPS will be the master, others will be slave - webinterface is only needed at the master, the slaves need to continue to work when the master is down.
Webinterface can even be hosted on another, offsite, VPS if it matters.

Any recommendations?

Thanks,
William

    PowerDNS (but build 3.1 from sources)

    @Zen - yes, we are using custom PowerDNS backends is a part of our solution.

  • Have you checked out nsd?
    PowerDNS takes too much memory when compared with its alternatives.. (I'd used their MySQL backend in the past)

    On our servers PowerDNS is using around 8MB

    nsd3 - no web-interface though, but fits in about 3 MB of RAM.
