    Wink dns reverse lookup for dns hosting


    Hi,

    I have two DNS servers in my office. One is configure to be the primary DNS server and the other one, secondary DNS server. In my company, we do things like DNS hosting for our customer should they need to have their Domain Name hosted. We normally used the Primary DNS server to do hosting for our customer.

    It apprears that i could only configure a "forward lookup query" for my customer's Domain Name zone file. and it works! No problem with that. My DNS is also configure properly, no trouble with that as well. Now, i got one question. For all those mail servers out there in the internet that would require a "reverse lookup" query for validation purpose, it would not work with my current setup. Cause the abvious answer is that the "reverse lookup" can only be done for my DNS servers and their zone files. But not for our customer's zone files. Should our customer requires should feature i.e: "reverse lookup" query for their zone files, is this feasible?

    Please help....... Thanks.

    This is how things would work:

    Some example zones your primary server (1.2.3.4) may be hosting:

    yourdomain.com
    4.3.2.1.IN-ADDR.ARPA

    customer1.com (2.3.4.5)
    5.4.3.2.IN-ADDR.ARPA

    customer2.com (3.4.5.6)
    6.5.4.3.IN-ADDR.ARPA

    Example zone contents:

    [yourdomain.com]
    @ SOA ns1 admin (...)
    @ NS ns1
    @ NS ns2
    ns1 A 1.2.3.4
    ns2 A 1.2.3.4

    [customer1.com]
    @ SOA ns1.yourdomain.com. admin (...)
    @ A 2.3.4.5
    @ NS ns1.yourdomain.com.
    @ NS ns2.yourdomain.com.
    @ MX mail
    mail A 2.3.4.5

    [5.4.3.2.IN-ADDR.ARPA]
    @ SOA ns1.yourdomain.com. admin (...)
    @ NS ns1.yourdomain.com
    @ NS ns2.yourdomain.com
    @ PTR mail.customer1.com.

    [customer2.com]
    @ SOA ns1.yourdomain.com. admin (...)
    @ A 3.4.5.6
    @ NS ns1.yourdomain.com.
    @ NS ns2.yourdomain.com.
    @ MX mail
    mail A 3.4.5.6

    [6.5.4.3.IN-ADDR.ARPA]
    @ SOA ns1.yourdomain.com. admin (...)
    @ NS ns1.yourdomain.com
    @ NS ns2.yourdomain.com
    @ PTR mail.customer1.com.


    As you can see, since it is not your IP addresses that are being used by your customers, there's no conflict in the reverse lookup zones. However, do you also host websites for your customers? That may throw a nasty wrench into the works.
    Send me a private message if you would like me to setup your DNS for you for a price of your choosing. This is the preferred method if your DNS needs to be fixed/setup fast and you don't have the time to bounce messages back and forth on a forum. Also, check out these links:

    thanks


    Hi,

    Thanks for that prompt reply. It make sense now We do have web hosting for customer as well, however it's being hosted on a different server.
