# DNS Find other nameservers: ```shell-session dig ns @ ``` Sometimes it's possible to get the version: ```shell-session dig CH TXT version.bind ``` Show all records: ```shell-session dig any ``` ### Zone transfers or Asynchronous Full Transfer Zone (AXFR) They use `TCP` port 53 ```shell-session dig axfr @ ``` If the administrator used a subnet for the `allow-transfer` option for testing purposes or as a workaround solution or set it to `any`, everyone would query the entire zone file at the DNS server. In addition, other zones can be queried, which may even show internal IP addresses and hostnames. Manual bruteforcing: ```shell-session for sub in $(cat /opt/useful/SecLists/Discovery/DNS/subdomains-top1million-110000.txt);do dig $sub.inlanefreight.htb @10.129.14.128 | grep -v ';\|SOA' | sed -r '/^\s*$/d' | grep $sub | tee -a subdomains.txt;done ``` ## Tool [DNSenum](https://github.com/fwaeytens/dnsenum) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.rtlcopymemory.com/footprinting/dns.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
