Thread: About dig output

  1. About dig output

    Hi,
    I have some questions about the output reading of "dig" utility.

    When I executed "dig @202.42.239.6 mydomain.com. any", the system
    gives the output consists of a word "AUTHORITY: 2" but sometime it
    stated as "AUTHORITY: 0".

    Could somebody explain what is meant by "AUTHORITY: 2" and "AUTHORITY:
    0"? What is the implication? Thanks.

    It's simply the number of entries that appear under the different "sections"
    of the dig output. For instance, "AUTHORITY: 4" means that there will be 4
    entries under the ";; AUTHORITY SECTION" of the dig output: e.g

    ;; AUTHORITY SECTION:
    excite.com. 130950 IN NS dns4.imgfarm.com.
    excite.com. 130950 IN NS dns5.imgfarm.com.
    excite.com. 130950 IN NS ns1-75.akam.net.
    excite.com. 130950 IN NS ns1-95.akam.net.
    ^ note: 4 entries

    The same is true for the "QUERY: x", "ANSWER: x", and "ADDITIONAL: x"
    fields. It's a summary of the number of responses from each section of the
    dig query.
