Bypassing WHOIS Rate Limiting and Alerting on Fresh Enterprise Domains

WHOIS data is a prime resources for identifying apex domains owned by a company. Unfortunately that data is typically locked up behind rate limited systems, third party APIs, or expensive bulk purchases. We developed whoiswatcher to run in serverless cloud (where we have clocked it at 1-1.5MM domains per day) or by using IPv6 proxying (can hit 150-200k domains per day with a small VPC). This makes it a perfect candidate to build a WHOIS dataset, review historic WHOIS records, and alert you on fresh enterprise domains. We will demo all this and more!
