You dont have to settle for the two extremes of tight-lipped and garrulous.

What is authority section in dig. DIG is more advanced than older tools such as nslookup and host commands. Authority contains the authoritative zone name for the response and the zone servers. This comment is printed by default.

You can toggle this section of the output using the noauthority option. In the question section dig reminds us of our query. First all resource records in the response contain TTLs no matter which section authority answer or additional theyre in.

The default is to display it. As mentioned on this answer the docs say. This displays the DNS name server that has the authority to respond to this query.

It is an acronym for Domain Information Groper and its intended to query the DNS of a given server and allows to know the answers from the queried domain servers. The AUTHORITY section tells us what servers are the authority for answering DNS queries about the queried domain. The subsequent fields Query Answer Authority and Additional provide the count of results for the DIG that was performed.

Noall Set or clear all display flags. The dig command allows you to selectively include or exclude sections from the results. 5DIG output have so much information than any other tool such as QuestionAnswerAuthority sections which we are going to discuses in this post Usage1.

Dig is a network administration command-line tool for querying the Domain Name System. In looking at the output of my own servers I see data in authority and additional sections. The dig command is helpful for troubleshooting DNS problems but is also used to display DNS information.

The rDNS lookup is performed using nibble format. If yes then when generating responses the server will only add records to the authority and additional data sections when they are required eg. In Answer the exact record for your query dig does an A by default if you do not specify anything in Authority you see what the recursive has learnt.

The IN means this is an Internet lookup in the Internet class. Ttlid Display do not display the TTL when printing the record. Second whether theres an additional section has nothing to do with whether the servers authoritative or not and just to complicate things a single DNS response can contain a mix of authoritative and cached data.

IN A The question section reaffirms what you went looking for - in this case DIG went. Answer Display do not display the answer section of a reply. That server may choose though to answer the query from a cache.

When a specific name server is not specified in the command invocation it uses the operating systems default. SOA specifies authoritative information about a DNS zone including the primary name server the email of the domain administrator the domain serial number and several timers relating to refreshing the zone. For a negative recursive response RDRA1 NXDOMAIN or NO DATA Response section is empty.

In looking at data from the output of those dns servers I do not. It stands for Domain Information Groper and it collects data about Domain Name Servers. The following query options will remove that section from the results.

The Authority section indicates the servers that are the ultimate authority for answering DNS queries about that domain. It can operate based on command line option and flag arguments or in batch mode by reading requests from an operating system file. Using DIG in basic form.

Lets see how the command works and how to understand its output. Nocmd Toggles the printing of the initial comment in the output identifying the version of dig and the query options that have been applied. The reason for this section is that you can query any DNS servers to answer a query for you.

This guide will help you understand and use the Linux dig command. This dig parameter will automatically perform a lookup for the traditional IP address name such as 9420192in-addrarpa and set the query type and class to PTR and IN respectively for the IPv6 addresses. Next dig shows the header of the response it received from the DNS server.

This displays the ip address of the name servers listed in the AUTHORITY SECTION. Dont show comment lines. Dig is useful for network troubleshooting and for educational purposes.

Authority section contains an SOA record with the Negative Cache TTL as parameter cf. The default query is for an Internet address A. The dig command in Linux is used to gather DNS information.

You can easily find out SOA start of authority record using command such as dig or host under UNIX and Linux like operating systems. The authority section tells us what DNS servers can provide an authoritative answer to our query. I suspect that the extra authority section is a result of that server not using the minimal-responses option.
