You should consider adding DNS checks prior to WHOIS. Whois is unreliable and you can be quickly blocked, doing a quick SOA DNS request can help reduce your WHOIS queries when the domain definitely exists (no SOA is not enough to confirm domain is unregistered but existing SOA is enough to confirm a domain is registered)
- indigodaddy 1y agoSo only do a whois when no SOA exists. That's clever.
- Brandutchmen 1y agoYeah! Excited to have a short circuit.

- Brandutchmen 1y agoThis is good to know! I'll migrate this over to RDAP
- Brandutchmen 1y agoI switched out whois with RDAP as the primary. It now goes RDAP -> DNS check -> whois. Much faster, too. Thank you again for this!
- Brandutchmen 1y agoGood advice! DNS check -> RDAP seems to be the right way to take this.
