ThatsMyType

DNS enumeration through targeted RFC queries.

Usage Instructions

1. Enter the path of the file containing target hostnames. This could be a list of hundreds or even thousands of domain names that you would like to resolve.
2. Select the DNS server to query. This could be a public resolver such as Google, or a private corporate DNS server that you are auditing.
3. Select the RFC type for your DNS queries. (ex: A, CNAME, PTR, TXT, MINFO, HINFO, ALL, ANY)
   • If you arent sure which option to use, the IANA DNS Parameters portal is a great place to start.
   • Results are saved in your working directory based on the type of query ran and the target resolver. (ex: resolutions-ALL-8.8.4.4.txt )
   • If the file already exists, ThatsMyType will append the existing file, so no results are lost.

Testing Methodologies

I created a spreadsheet using the IANA resources provided from the webpage above. It has served me as a good reference for testing possible DNS types. The spreadsheet is available in the docs folder here.
