What are you doing to prevent others using you as a whois proxy?

Alternately, how are you planning to evade the (rather restrictive) rate limits which whois servers impose?

it's a goal to use the advertised IP blocks of cloud providers where possible, with whois simply as a fallback.

Will happily accept patches for other providers.

You realize that the majority of IPs submitted may not be from a known cloud provider/test suite, and so you're still dealing with the rate limiting from falling back for most requests?

I built this library to track signups for an application that has a fairly low request rate.

if you need a higher request rate 🤷 ¯\_(ツ)_/¯ pitch in and help add support for a wider variety of cloud providers.
