DNS setup

This documentation is for legacy Kiwi Syslog Server versions 9.8.2 and older.

To view or edit DNS setup information:

  1. Choose File > Setup to open the Kiwi Syslog Server Setup dialog box.
  2. Expand the DNS Resolution node.
  3. Click DNS Setup.
  4. Under Internal IP address - Name Resolution, specify the following options:

    Internal IP address range(s)

    A list of masked IP addresses that identify your internal network address space.

    The default entries in this list are standard internal (private) network address spaces, as identified in RFC1918/3330/3927. These include IANA reserved private internet address spaces, and the link-local address range.

    10.0.0.0 - 10.255.255.255 (10/8 prefix) 172.16.0.0 - 172.31.255.255 (172.16/12 prefix)

    192.168.0.0 - 192.168.255.255 (192.168/16 prefix) 169.254.0.0 - 169.254.255.255 (link-local)

    Adding an internal IP address range:

    Enter the masked IP address in the text box directly underneath the "Internal IP address range" list, and click the "Add" button.

    IP addresses must be masked with an "x" character, the "x" signifying that any value within the range (0-255) is acceptable.

    For example, if you have an internal address space of '10.0.0.0' - '10.255.255.255', you should enter the masked IP address as '10.x.x.x'.

    Syslog host IP addresses which match any of these address ranges will be resolved according to the options which are set for "Internal IP Address - Name Resolution" only. Those host IP addresses which do not match any of the internal address ranges will be resolved according to the options which are set for "External IP Address - Name Resolution". This distinction is important - the address range list essentially acts like a filter. The filter determining whether to try and resolve an IP address on an internal network using local DNS servers or NetBIOS, or whether to try and resolve the IP address with an external DNS server, etc. Ensuring that your internal address space is setup correctly can have a direct bearing on the turn-around times of each name resolution query.

    Resolve internal addresses using NetBIOS

    If checked, Kiwi Syslog Server will attempt to resolve the internal IP address by sending a NetBIOS broadcast query to the local subnet.

    Resolve internal addresses using DNS server

    If checked, Kiwi Syslog Server will attempt to resolve the internal IP address by sending a DNS query to a DNS server.

    Preferred/Alternate internal DNS server addresses

    These entries determine which internal network address the DNS query will be sent to.

    By default these addresses are auto-detected by Kiwi Syslog Server, and depending on your network configuration may need to be altered.

    If the preferred DNS server is unavailable or cannot service the request, the same query will be asked of the alternate DNS server.

    If no alternate DNS server is available, then this address is to be left blank.

  5. Under External IP address - Name Resolution, specify the following options:

    Resolve external addresses using NetBIOS

    If checked, Kiwi Syslog Server will attempt to resolve the external IP address using NetBIOS.

    Resolve external addresses using DNS server

    If checked, Kiwi Syslog Server will attempt to resolve the external IP address by sending a DNS query to a DNS server.

    Preferred/Alternate external DNS server addresses

    These entries determine which external network address the DNS query will be sent to.

    By default these addresses are auto-detected by Kiwi Syslog Server, and depending on your network configuration may need to be altered.

    If the preferred DNS server is unavailable or cannot service the request, the same query will be asked of the alternate DNS server.

    If no alternate DNS server is available, then this address is to be left blank.
