    dns cluster or each server's own dns


    do you host all the dns on the dns cluster ?
    or each server have their own dns ?

    if each domain only put all the websites data/service on one server,
    i think it is non-necessary to host the domain on dns cluster,
    because if the web server fail,
    all the service can not show even if you host dns out out the server.

    and i ever find certain registrar's dns under ddos,
    and all the domain forward/sub domain/a address record setup on their dns are fail,
    all ns1/ns2/ns3/ns4 under attack,
    if all your client's domain host on it and can not work,
    i think it is big issue at all...

    but setup separate dns for each server,
    i will need to waste more ip i think,
    becuase at least you need two ip as dns for each server.

    for your experience,do you recommend which one way?

    A possibility is having various servers outside of the cluster, but all linked through DNS.
    You could even hire a few cloud VPS to run DNS servers on.

    if there's any chance of DDoS, then use own NS's per every physical server.

    If you do not expect to have any DDoS attack, I recommend one dns-server not to create dns instances.

    If DDOS is such a big issue you might address it first before thinking of DNS and clustering.
