GoWC

A fast & accurate tool to clean wildcards from Massdns output file.
This is not a wrapper. A wrapper will have massdns's parameters fixed inside, what is not my style. Massdns should be used in flexible way.
Generally, algorithm is based on puredns, but there are few changes to make the algorithm more accurate and faster.

GoWC, first it will ask for NS of target domain (Ex. ns1..com, ns2..com). Then, belong with Google & CloudFlare DNS, these NS will be used to clean wildcards faster and more accurate. Why? Because sometimes, ns1 (of target) could accept wildcard subdomains, but ns2 doesn't that lead to False Positive. This tool will solve all these problems.

What's new

• With GoWC v1.3.5, wildcard subdomains will be cleared faster, and more accurate. You now can set some more options:

  -s, --timeout= Timeout in seconds (default: 5)
  -q, --qps=     Queries per second (default: 10000)
  -r, --retries= Max retries each failed query (default: 1)

• All progress info just be printed to stderr. Only valid subdomains will be printed to stdout.
