###### This script will attempt a [Zone Transfer](https://en.wikipedia.org/wiki/DNS_zone_transfer) on all of the [Root Nameservers](https://en.wikipedia.org/wiki/Root_name_server) and [Top-level Domains](https://en.wikipedia.org/wiki/Top-level_domain) *(TLDs)*.
|
||||
|
||||
## Expectations & Legalities
|
||||
Please set realistic expectations when using this tool. In contemporary network configurations, AXFR requests are typically restricted, reflecting best practices in DNS security. While many nameservers now disallow AXFR requests, there may still be occasional instances where configurations permit them. Always exercise due diligence and ensure ethical use.
