It’s network administration tool which will help them to check and troubleshoot DNS related issues. Non-interactive mode is used to print just the name and requested information for a host or domain. Interactive mode allows the user to query name servers for information about various hosts and domains or to print a list of hosts in a domain. Nslookup has two modes interactive and non-interactive. Nslookup is a program to query Internet domain name servers. Other lookup tools tend to have less functionality than dig.Ģ) Check DNS Records Using NSlookup Command Most DNS administrators use dig to troubleshoot DNS problems because of its flexibility, ease of use and clarity of output. It performs DNS lookups and displays the answers that are returned from the name server(s) that were queried.
Once changed, change the query type (Step 3) if needed then enter new a new domain (Step 4.)ĭig stands for domain information groper is a flexible tool for interrogating DNS name servers. Replace with the Name Servers you wish to use. This is useful if you are checking the records before DNS has fully propagated. You can also change the Name Servers which you are querying. NSLOOKUP will now return the record entries for the domain you entered. Now enter the domain name you wish to query then hit Enter. You may use ANY, A, AAAA, A+AAAA, CNAME, MX, NS, PTR, SOA, or SRV as the record type. Set the DNS Record type you wish to lookup by typing set type=# where # is the record type, then hit Enter. The default Server is set to your local DNS, the Address will be your local IP.

Launch Windows Command Prompt by navigating to Start > Command Prompt or via Run > CMD. You may find the need to check the status of your domains DNS records, or check the Name Servers to see which records the servers are pulling. flags: qr rd ra QUERY: 1, ANSWER: 18, AUTHORITY: 0, ADDITIONAL: 0 >HEADER<<- opcode: QUERY, status: NOERROR, id: 10403 Test "$')ĭig +nocmd $NS "$DOM" +noall +answer "$TYPE" The new script takes a -x argument for expanded output and a -s NS argument to choose a specific nameserver: dig -x #!/bin/bashĬOMMON_SUBDOMAINS="www mail mx a.mx smtp pop imap blog en ftp ssh login" I've also disabled the filtering of wildcard IPs because usually I'm usually more interested in the correctness of the setup. I've noticed that dig only shows entries already present in the queried nameserver's cache, so it's better to pull an authoritative nameserver from the SOA (rather than rely on the default nameserver). Note that subdomain enumeration is usually not exhaustive. There are some online tools that enumerate subdomains, and online tools that list all DNS records for a DNS name. You'd have to iterate through all the DNS record types, and also through common subdomains, depending on your needs. Option 3: Scrape with a scriptĪnother option is to scrape all DNS records with a script. This is a shared secret the client can send to the server to authorize the transfer. If you have control of the zone, you can set it up to get transfers that are protected with a TSIG key. You'll usually conduct a zone transfer directly from the authoritative server (the below) and often from a name server that may not be published (a stealth name server). However, these are typically restricted and not available unless you control the zone. Option 2: AXFR queryĪn AXFR is a zone transfer, and is likely what you want.
The name server does not have to return these records if it chooses not to do so (for example, to reduce the size of the response). However, it will not return child records (e.g., More precisely, you MAY get these records if they exist.
This may return A records, TXT records, NS records, MX records, etc if the domain name is exactly "". When you query for ANY, you will get a list of all records at that level but not below. The short answer is that it's usually not possible, unless you control the domain.
