Does hitting this command in unix have a rate limit?
$whois somedomain.com
What is the limit on this?
Solution 1:
You'll probably get rate-limited by the whois servers before you get limited by the OS. If you really need access to tons of whois records Google for "bulk whois". Here's how to request bulk whois records from ARIN: https://www.arin.net/resources/request/bulkwhois.html
