## What it is
ksubdomain is a stateless subdomain enumeration tool written in Go that performs extremely fast DNS brute-forcing by separating packet sending and receiving without relying on system sockets. It supports verification of existing domain lists, wildcard filtering, ASN/IP summary output, and pipeline integration with tools like subfinder and httpx.

## Use cases
- enumerate subdomains of a target domain quickly
- brute-force DNS entries with a custom wordlist
- verify a list of candidate subdomains actually resolve
- filter out wildcard DNS responses during enumeration
- pipe subfinder results through ksubdomain and httpx for live-host discovery
- summarize discovered domains by ASN and IP ranges
- test maximum local packet sending rate
